  1. Fellow Forum Members, I am buying a more powerful Xeon CPU for my Supermicro X10SRH-CF motherboard. However, I have already done the initial Parity work to setup a new UnRaid array for the first time. Is my UnRaid array going to break after I change Xeon CPUs? The old one has six cores and the new one has 12 cores. So I think it is a worthwhile upgrade. Also, if I want to just go ahead and delete my UnRaid array to build it for a second time after I install the new XEON CPU how do I go about doing that? I can't find any button that says, "Delete UnRaid Array" to do the initial Parity build process over again. Lastly, do I run the risk that doing the Parity process for a second time on the same collection of hard drives may result in an unstable UnRaid Array? Any help will be greatly appreciated.
  2. Correct. My old 20tb RAID6 Array is filled to capacity. It utilizes 10 hard drives and when I boot up this old machine all the data stored on it appears on my old Windows7 system as a single folder. In short, I need to move all 20TB of data over to my new UnRaid System build and thanks to how you mentioned to look into Krusader and Unassigned Devices this task is less of a mystery to me now. The YouTube video in the link below gave me a great insight to Krusadar: https://www.youtube.com/watch?v=I0XCFPAsWZE Before watching this video my thinking was I was going to have to CAT6 cable connect both my 20TB RAID6 machine and my new UnRaid Array to a common router and transfer the data within a network. However, after watching this Krusader video I now learned it is possible to connect both machines via a USB connection to move data between them. I have to research "unassigned drives" a bit more because I do not fully understand how to make that happen. Does using Krusader eliminate the expense of buying a 4tb cache disk and instead downgrade to a smaller size cache disk? Lastly, does anybody know a good link that shows the best way to transfer data from an old RAID6 machine over to a new UnRaid machine using Krusader and Unassigned drives?
  3. Wobblewoo, thanks for the post. Your description of how you are using a cache disk makes a lot of sense. However, what if you have 20tb of data stored in an old RAID system you need to transfer over to your new UnRaid system? Wouldn't such a task get done faster if it was done using a 4tb cache disk as opposed to 500gb cache disk? Please reply back with a post if you think there is something wrong with this reasoning. I do not claim to be an expert. I am on this forum to learn how to best build and use the new UnRaid system I am building.
  4. Thanks to all for your posts. According to the UnRaid online manual (shown below as a copy and paste) the "Cache pool mode" utilizes an untraditional RAID 1. So to answer my orignal question, the UnRaid OS does support mulitiple drives but using a hybrid form of RAID 1. In short, I hope the next release comes out soon which Tjb_altf4 says will support multiple cache pools and do what I want it to do. My reason for having two drives is because I want to keep all my docker apps contained in a single hard drive. And use the second drive as a temporary data parking place to slowly fill it up with data. Once the second drive fills up the data is migrated over to an UnRaid drive. My hope is the UnRaid OS will not reject the PCI Adapter Card installed with two NVME drives and instead recognize it for use in a Cache Disk pool. Can anybody out there confirm if setting up a Cache Disk Pool will encounter a problem if the PCI Adapter card shown in the link below is used? https://www.amazon.com/gp/product/B01FU9JS94/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Any opinions welcome. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Cache pool mode When more than one disk is assigned to the cache, this is referred to running in cache pool mode. This mode utilizes btrfs RAID 1 in order to allow for any number of devices to be grouped together in a pool. Unlike a traditional RAID 1, a btrfs RAID1 can mix and match devices of different sizes and speeds and can even be expanded and contracted as your needs change. To calculate how much capacity your btrfs pool will have, check out this handy btrfs disk usage calculator. Set the Preset RAID level to RAID-1, select the number of devices you have, and set the size for each. The tool will automatically calculate how much space you will have available.
  5. Fellow Forum Members, I know the UnRaid OS supports a single cache disk. But can it support 2 cache disks? I ask because the Cache Disk setup I am contemplating is one where Cache Disk #1 is used for docker apps to install to. And Cache Disk #2 is used as a data transfer drive to migrate files to UnRaid drives. Can the UnRaid OS support such a Cache Disk configuration? Below is a list of the hardware I'm contemplating to buy. Dual M.2 PCIe SSD Adapter Card https://www.amazon.com/gp/product/B01FU9JS94/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Cache Disk #1 = 1TB NVME https://www.amazon.com/Samsung-970-EVO-1TB-MZ-V7E1T0BW/dp/B07BN217QG/ref=sr_1_3?dchild=1&keywords=1tb+nvme&qid=1590805806&s=electronics&sr=1-3 Cache Disk #2 = 4TB NVME https://www.amazon.com/Sabrent-Rocket-Internal-Performance-SB-RKTQ-4TB/dp/B087N7HLRV/ref=sr_1_2?dchild=1&keywords=4tb+nvme&qid=1590805879&s=electronics&sr=1-2 Any opinions on this dual Cache Disk setup I'm contemplating will be welcome.
  6. Hugenbdd, Thanks for your post. I found it to be very helpful and eye opening. Your suggestion is one that makes a lot of sense. Hypothetically speaking, let's say I have the StarTech PCI adapter card installed on my bifurcated motherboard and on that PCI card I have a 1TB and 4TB NVME card installed. Is it within the UnRaid OS setup parameters to use the 1TB card strictly for the Docker apps to install to? And use the 4TB card only to perform fast data transfer operations to the UnRaid array? According to the link below making that happen is problematic. https://forums.unraid.net/topic/39561-add-second-cache-drive/ Hugenbdd, can you share if your UnRaid OS successfully recognizes two separate NVME cards as two separate cache disks? It will help me out a lot if you can expand on this matter.
  7. Thank you Squid and Whipdancer for your posts. Drive encryption makes sense to me as the possible cause to all the excessive writing going on in some cases. Today I got on the phone with Sandisk Tech Support. They pointed me to a 4tb WD Red SA500 SSD with a higher TBW that looks promising. The list below summarizes what I know so far: The 4TB "WD Red SA500 NAS SATA SSD" has a 2500 TBW and sells for $579 The 4TB "Sandisk 3D NAND" has a 600 TBW and sells for $499 The 4TB "Samsung 860 PRO SSD" has a 4,800 TBW and sells for $1,000 The 4TB "Samsung 860 EVO SSD" has a 1,440 TBW and sells for $650 The 3.84TB "Seagate IronWolf 110 Series SSD" has a 7,000 TBW and sells for $869 If going by price and TBW alone the "Seagate IronWolf 110 Series SSD" is the best SSD you can buy to use as an UnRaid cache disk. It has a higher endurance rating than the "Samsung 860 PRO SSD" and it also costs less than the "Samsung 860 PRO SSD". However, for some reason I don't understand it is slightly smaller than 4tb. Nevertheless, spending $250 on a 5TB mechanical hard drive to use as an UnRaid cache disk still seems mighty appealing to my wallet. For now I look forward to reading any opinions anybody is willing to share regarding this matter.
  8. Fellow Forum Members, Is it true the UnRaid OS and various of its docker apps eat through the Tera Byte Written (TBW) threshold of an SSD cache disk due to how it writes an excessive amount of data to the cache disk? This is a concern to me because the Sandisk 4tb SSD has a 600 TBW and sells for $500. In contrast, the Samsung 860 Pro SSD costs $1000 and has a 4,800 TBW. So the Samsung SSD has a lot longer life before it fails and is out of warranty. On the other hand, the Sandisk 4tb drive will probably burn out before its warranty runs out. Given all of that does it make more sense to just buy a 5tb mechanical hard drive for $250 and use it as an Unraid cache disk instead of a 4tb SSD? This way I don't have to worry about premature SSD failure which seems to be a problem due to how the UnRaid OS inflicts a lot of wear onto an SSD drive. And since the 5tb cache drive is going to work while I am asleep does it really matter it has half the data transfer speed of an SSD drive? Or does not opting to not use an SSD drive as a cache disk defeats the entire purpose of having a cache disk in the first place? I would be curious to know if anybody in the community is using a mechanical hard drive as a cache disk and if they are happy with it. In short, I am just trying to figure out the best possible hardware to use in setting up a cache disk for my new UnRaid system. Any opinions welcome.
  9. Thank you to all for your posts. Correct, I am a newbie as it relates to setting up an UnRaid system. And I am glad I checked before buying a PCI addon card that most likely was going to end up being incompatible with my UnRaid OS. I plan to spend more researching the details relating to the addition of a Cache Disk after the UnRaid array has already been setup.
  10. Fellow Forum Members, I have a Supermicro X10SRH-CF motherboard. I am setting up a UnRaid Cache Disk using two 2TB Crucial MX500 SSD drives setup as RAID 1. Is the SUPERMICRO AOC-USAS2-L8i card shown below compatible with the UnRaid OS? The card claims a transfer speed of 6gb/sec. For a lot more money I could buy the Supermicro AOC-S3008L-L8I which claims a transfer speed of 12gb/sec. Is the UnRaid OS capable of supporting 12gb/sec. transfer speeds? If no, then I will just save my money and buy the card with the 6gb/sec. transfer speed. If anyone has a recommendation for a better card please share. Any opinions welcome.
  11. My goal is not to use any of the remaining SATA and SAS ports I have remaining on the motherboard because I am going to need them in the future. Therefore, I need to buy a PCI SATA Controller card. Is anybody out there running a Supermicro motherboard with a PCI SATA Controller card installed? If yes, can you please share the model number of the PCI SATA Controller card you are using. I just want to buy a good card that is compatible with my Supermicro motherboard. Thank you for any help.
  12. Fellow Forum Members, My UnRaid OS is running on a SuperMicro X10SRH-CF motherboard, with 64GB of ECC RAM and a XEON processor. I need to add a Cache Disk to an existing UnRaid Server which today successfully completed a Parity Setup Process that lasted 27 hours. Additionally, all hard drives have been successfully formatted. However, I am not creating shares at this time because I first want to complete work on setting up a Cache disk. I am thinking of buying two 2tb Crucial SSD drives shown in the link below: https://www.newegg.com/crucial-mx500-2tb/p/N82E16820156175 Originally I wanted to go with two Samsung Pro 2TB SSDs but the price is crazy: https://www.newegg.com/samsung-860-pro-series-2tb/p/N82E16820147680 I need help with selecting a PCI SATA controller card that is compatible with my SuperMicro X10SRH-CF motherboard. Because I am not sure if the PCI SATA Controller card shown in the link below is going to successfully work with both my SuperMicro X10SRH-CF motherboard and my UnRaid OS: https://www.newegg.com/p/3C6-00CH-047Z5?Description=PCI SATA controller card&cm_re=PCI_SATA_controller_card-_-9SIAK7VBHX4215-_-Product Some closing questions: Are the Crucial SSDs as good as the Samsung Pro SSDs for use in a Cache Disk setup? My thinking is why spend the extra money if the specs are a close match. Is the PCI SATA controller card I am considering the best one in terms of throughput data speed, quality and compatibility with my SuperMicro X10SRH-CF motherboard? If not can someone please recommend a better one? Will my UnRaid OS be able to recognize my RAID 1 Cache Disk setup as a single hard drive? Lastly, what is the best RAID configuration to use for a Cache Disk setup? RAID 0? RAID 1? Or RAID 5? Any opinions will be greatly appreciated.
  13. Constructor, Thank you very much for your post. I honestly thought I had to start the entire parity process all over again which gave me a sick feeling. So I got 5 hours to go. After the parity process is done in five hours all I have to do is format the drives and then in theory my parity drive should no longer show that orange triangle anymore. Am I correct?
  14. Fellow Forum Members, I am in the process of setting up my UnRaid Array for the first time. I noticed a small orange triangle next to the Parity drive and it reads: "Parity is invalid. Click to spin down device" What usually causes this message to appear? And once I spin the drive down do I need to start all over again with the parity process? What is the fix to prevent this message from appearing again? Any advise will be greatly appreciated.
  15. Thank you to all for your posts. My goal is to use some kind of PCI based storage for my Cache Disks because I want to avoid utilizing the few remaining SATA ports I have left on the motherboard and use them for a later time in the future for actual data storage drives. So allow me to ask the question in a different way. Is a preferable Cache Disk setup to just buy a PCI 4SATA Port RAID controller card and add four 1TB SSD drives all in RAID setup? Is this a preferable Cache Disk setup compared to buying an "M.2 To PCIe Adapter" installed with 4 NVME cards? Are the data throughput speeds the same for both options or does 4NVME option provide a lot more data throughput? And does the UnRaid OS prefer one option over the other? And am I correct to think bifurcation support is not an issue with option involving the use of a PCI 4SATA Port RAID controller card? Bottom line, I just want to know what is the best Cache Disk setup to employ if the goal is to use a 16x PCI slot and not SATA ports on the motherboard? Any opinions welcome.
  16. Fellow Forum Members, Is the latest OS version of UnRaid compatible with "M.2 To PCIe Adapters" like the ones shown in the links below: https://www.sybausa.com/index.php?route=product/product&path=64_205&product_id=1035 https://www.newegg.com/asus-model-hyper-m-2-x16-card-v2-pci-express-to-4-x-m-2/p/N82E16815293043?Item=N82E16815293043&Description=m2 pcie ssd adapter&cm_re=m2_pcie_ssd_adapter-_-15-293-043-_-Product&quicklink=true My idea is to use these "M.2 To PCIe Adapters" as Cache Disks for my UnRaid server. The actual Cache Disks will be a set of 4 NVME cards setup as RAID. My motherboard is a Supermicro X10SRH-CF so I do not think there will be a problem with the motherboard being compatible with this device. My only uncertainty is if the UnRaid OS is going to be compatible with this hardware. Any opinions welcome.
  17. Thank you for the post Constructor. I will avoid adding dockers until I first purchase the cache disks and install them onto my UnRaid server. Does anybody have any opinions on the "M.2 To PCIe Adapter" hardware I'm considering to use. Does UnRaid support such "M.2 To PCIe Adapter" hardware for use as a cache disk? Any opinions welcome.
  18. Thank you for your post. I am using a Supermicro X10SRH-CF. It has two LAN ports and one IPMI port. From what I gather I need to have two separate CAT6 cables connected to this motherboard. It would have been cool if it only required a single CAT6 connection instead. Additionally, I updated the BIOS from 1.0b to 3.2 and the Firmware to the latest 3.82. So doing that did not give the IPMI LAN port the ability to support the IPMI software and the UnRAID OS simultaneously as I was hoping.
  19. Fellow Forum Members, My SuperMicro motherboard has an IPMI LAN port and it also has two additional plain LAN ports. When I connect a CAT6 cable from the IPMI port to my NetGear Router I am able to operate my SuperMicro motherboard BIOS remotely from a different computer that is also connected to the same NetGear router. However, trying to operate my UnRaid OS while connected to my IPMI LAN port does not seem to work. Am I correct or incorrect to think both my UnRaid OS and my SuperMicro IPMI software can both work from a single IPMI LAN connection on a remote computer? Or does it require I have an IPMI LAN connection as well as a separate LAN connection setup on my SuperMicro motherboard so I can successfully operate both the UnRaid OS and IPMI software from a remote computer? Any opinions welcome.
  20. Fellow Forum Members, Performing a Parity and hard drive initialization setup for the first time on my new UnRaid system is going to take 20 hours of waiting! For financial reasons I elected not to setup a pair of 2TB SSD cache disks at this time. Is it very difficult to add cache disks at a future date after an UnRaid array is already completely setup with all hard drives assigned and formatted? I am curious to know if it requires I wait another 20 hours for electing to postpone the addition of cache disks to a later time in the future? Or do the cache disks operate outside of the UnRaid array which means no future 20 hour wait is necessary? Lastly, for my future UnRaid Server Cache Disk setup I am considering to by an "M.2 To PCIe Adapter" like the ones shown in the links below: https://www.sybausa.com/index.php?route=product/product&path=64_205&product_id=1035 https://www.newegg.com/asus-model-hyper-m-2-x16-card-v2-pci-express-to-4-x-m-2/p/N82E16815293043?Item=N82E16815293043&Description=m2 pcie ssd adapter&cm_re=m2_pcie_ssd_adapter-_-15-293-043-_-Product&quicklink=true Is anybody in the UnRaid community using "M.2 To PCIe Adapter" as an UnRaid cache disk setup? Is this solution offer better results compared to using a pair of 2tb SSD hard drives? What I like about it is how I do not have to rely on using any of my motherboard SATA ports which I want to keep as spares. Any opinions welcome.
  21. Fellow Forum Members, I'm running my UnRaid OS using my FireFox browser and when I attempted to setup a ROOT password in the USERS section my FireFox browser warned me my UnRaid server is not secure due to how it is utilizing HTTP and not the HTTPS protocol. This warning appeared as a popup message below the password field as I was trying to type in a password. So I put the brakes on setting up a ROOT password until I understand what is going on between HTTP vs. HTTPS as it relates to setting up the UnRaid OS. Can anyone in the community please clarify if the UnRaid OS when correctly configured uses "https://Tower" or a "http://Tower"? I ask because I am getting access to my UnRaid OS relying on the HTTP protocol. However, the Firefox warning is making me wonder if I screwed up something in my UnRaid OS configuration and therefore I am incorrectly using HTTP when I should correctly be using HTTPS. Is everybody in the UnRaid community using HTTPS or HTTP? Any opinion welcome.
  22. Thanks to all for your posts. I was not aware of what a simulated sinewave UPS is about. I think the one shown in the link below is a better option: https://www.amazon.com/CyberPower-CP1500PFCLCD-Sinewave-Outlets-Mini-Tower/dp/B00429N19W However, can anyone in the community please confirm if UNRAID's APC daemon operates correctly with the CyberPower UPS connected to the UNRAID system with a USB cable? Will I have the ability to perform a graceful UNRAID shutdown with the APC daemon controlling my CyberPower UPS? Alternatively, does UNRAID offer a CyberPower UPS Daemon addon I can use instead of the APC Daemon? Any opinion welcome.
  23. Fellow Forum Members, I got a CyberPower CST135XLU UPS at Costco for $99. It has a USB Type B connection on the backside. Is this USB Type B connector a 100% assurance my CyberPower CST135XLU UPS is going to work smoothly with my UNRAID UPS settings software? If the answer is no, can anyone please recommend an APC UPS in the $100 to $200 price range that is 100% compatible with the UNRAID UPS settings software? Is the APC BR1500G a solid choice? Or does it require I buy the more expensive APC Smart-UPS C 1500VA 2U Rack mountable LCD 230V? My UNRAID configuration has ten hard drives, a 750W Seasonic and a SuperMicro motherboard. In other words, it is not a monster system. However, I do want my UNRAID system to be able to perform a soft shutdown so I can avoid going through very long parity checks caused by abrupt loss of power. Any opinions welcomed.
  24. Thanks Frank1940! You are correct about it being an old version. Why don't the UNRAID development team offer this important online documentation as a PDF? It would help tremendously because in my case I need to study the UnRaid instruction content during my lunch hour at work and I don't have access to a computer during my lunch hour. Honestly, for what they are charging us for the UnRaid software itself I think we are entitled to a portable version of the manual we can print out and carry around where ever so we can study the content without being chained to computer screen. Just my two cents. :-)
  25. Fellow Forum Members, The two dropbox links CarlosCo posted no longer work. I would be very grateful if someone in the community can post new Dropbox links containing PDF versions of UnRAID 6/Getting Started manual. Or even better, can anybody in the community please point me to a working link where I can download the PDF from right now? Thank you for your time.
