Out of curiosity, if/when i try to format, is there a preferred format type i should use? This is a 3TB Spinny drive (Seagate Desktop drive i believe). Cheers.

Alright, let me give some more context. I HAD a diffeernt windows server im now moving ton unraid + VM (windows). the old windows server had a secondary drive which had my downloads and some data files etc. I was hoping that i could plugin this secondary drive into the new VM and still keep the old files that were on it. I was initially intending on creating a folder saying "backups" and chuck everything in there and later (when i have more time) just delete what i dont need and clean things up, but the permission issue did not allow me to do so. So now, im trying to copy everything into the main Raid (this is going to take a long time) so i can format and hope that i dont get the same permission issue. So essentially, i wanted to do the "cleanup" process later rather than sooner. Ah well, just means my plans will be set back by a day or so.

Hey guys, can someone please help me with something regarding Unassigned Devices. Im new to unraid, and pretty noob at these things. I installed Unassigned Devices, added 2 devices that are not in the main raid (ssd and a normal drive). The SSD is freshly formatted, but the normal drive still has the old data in it (ntfs). Both drives get picked up by UD and manage to mount them and the tick for "share" works as expected. Once shared, im using another PC to browse to the drives/folders. When i do so, i can add/modify files on the SSD but not on the Spinny drive "permission denied" (i tried moving some files, i tried adding a file to the root, etc). Is this expected behaviour or am i doing something wrong? Im using Windows 10 to make these edits. Im trying to move some of the data out of the spinny drive so i can format it, maybe that might fix it. Also another question i have is, if there is a way to share one of the disks with the VM running on the same unraid install without having this drive exposed on the network? So, sort of restricted access just for the VM. I have a W10 VM installed in the same unraid, and the VM is installed in the unraid arrays cache drives, i just want to pass through this spinny drive into the VM as a secondary drive.

Awesome, thanks so much. I also came accross clodflare and dyndns docker too, not sure how good that is, maybe i can give it a try (i use cloudflare to manage dns for all my domains, so might be ideal if i can use a subdomain of one of my own domains rather than a free one). Will give this one a go too

Hey Guys, I have unraid running at home in a box. I was wondering, if there is a way to get a domain/subdomain that gets updated any time my home network ip gets changed? Im happy to use my own domain name or some other free service that offers free subdomains. So at the end of the day, i want to be able to type myunraid.example.com to automatically map to my home external ip address. Is there any plugin or docker app that can do this? Cheers.

Hmm, its a little annoying that i have to choose between either 2 ssds or 2 hdds. Out of curiosity, what if i chose to have 2 ssds with slightly different capacity and slightly different sizes. Lets say 450MB/s vs 500MB/s and 240GB vs 250GB. Would that cause any issues?

Here's a link to the thread about cache pool speed and size: http://lime-technology.com/forum/index.php?topic=49047.0

Hey Guys, So here is what i know about the cache pool. Its by default using btrfs (i dont know much about this) and uses something similar to raid 1 (mirror). The unRaid cache pool accepts multiple drives (im unsure if there is a limit). So i have few questions regarding this. i have couple of SSDs sitting around and couple of spinny disks as well. And im hoping to use as many as i can as my cache to maximise the speeds and capacity of my cache pool (as the unRaid main data pool is far too slow for normal writes). Anyway, for sake or argument, lets say i have 2x 240gb SSDs and 2x 1tb Spinny Drives (WD Blues). 1. Given the above drives, is it wise for me to add all 4 drives into the cache pool, or should i only add either the 2 ssds or the 2 spinny drives? 2. If its fine to add all 4 drives to the cache pool, then what sort of capacity would i get as a result for the cache? 3. If its fine to add all 4 drives to the cache pool, then what sort of SPEEDs would i expect from the cache pool? (lets say individually the SSDs can do 500MB/s and spinny drives can do 100MB/s). Thats all for now, Thanks in advance

Actually, i feel this question deserves its own thread. Others might benefit from it, let me create one and i will link it here if any of you want to contribute.

@gundamguy, thanks for the link So, what would happen if i plug in 2x 240gb ssds and 2x 1tb spinny drives and add them all to cache pool. What would i end up with?

i dont quite get the options in the calculator, but i will google around a bit and take your word for it. Either way though, if you have a 100gb drive and 200gb drive in btrfs and the drive pool states 150gb usable, then if you use all the 150 gb, and somehow lose the 200gb drive, then you would need some crazy sorcery or time travel to be able to get back the data (atleast the missing 50GB). So, i dont quite understand the logic of this btrfs thing. Has anyone tested this? So your cache pool is safe as long as your largest drive, and if that dies, then all is lost. Do you by any chance have a link to this "unassigned devices plugin"? i will google shortly, but incase if i end up with something old/incorrect might be a great if you have a link and if you know of it. If i want to pass through a separate HDD (one that is not in the raid/cache) to my VM, is this what you use? I was told in another thread that you can pass drives into your VM without having to have the drive as a part of the raid, i just wasent told how i do that.

It's not 360GB because it's the default settings for cache pools is as a RAID 1 not RAID 0. The original point of adding BTRFS and cache pool capabilities was to add redundancy for cache drives so data sitting on the cache drive was protected from drive failure. You can change it to a RAID 0 pool if you want though. Ah, that makes sense. Hmm, if its raid 1, then shouldnt it say 120GB though (size of the smallest drive)? Where would i change this Raid 1 -> Raid 0 setting? Also, out of curiosity. I plan on installing couple of VMs (windows) on this machine (which will run purely on the cache). I do like the Raid 1 Redundancy for the cache for the main data drive pool, but its not necessary for the VMs. Is there any way for me to add a seperate drive for the VMs that is outside of the main cache pool? Also, what happens if i add few drives to the cache pool while it remains in Raid 1. Say 2x 240GB SSDs and 2x 1TB Spinny Drives. What sort of a cache pool monstrosity would i get, and what sort of pool size would it be?

Hey all, Im new here and new to unraid. Just got setup, i just have couple of questions on best way to do couple of things. So, this thread is about, what is the best process to replace a drive. First of all, there are 3 types of drives: Parity Drive Data Drive Cache Drive And there are 2 types of "replacement": Drive Swap: Swap out one drive (old existing) for another (new). This could be either due to drive upgrade or due to drive failure Drive Remove: This is only applicable for Data and Cache drives only, but suppose it might make sense for Parity in 6.2.x. But this is when you say you have 5x4tb data drives (20tb) and only using 10tb of data. So you can technically safely remove 2 of the data drives (probably not at the same time) and still have 2TB remaining. This could either be because of downgrading the raid or downgrading due to drive failure So, now that the scenarios are out of the way. Can someone explain what the best way to do the following: 1. Parity Drive Swap (upgrade) 2. Parity Drive Swap (replace due to failure) 3. Data Drive swap (upgrade) 4. Data Drive swap (replace due to failure) 5. Data Drive Remove (downgrade) 6. Data Drive Remove (downgrade due to failure) 7. Cache Drive swap (upgrade) 8. Cache Drive remove Just to add some curve balls, lets say that i have a raid with 1 parity and 3 data drives. For the cases (3) listed above, lets say we remove 1 data drive and add 1 new data drive in its place and let the raid rebuild that new data drive from the parity. In this scenario, if another drive fails, then you potentially lose entire raid (because you technically lost 2 drives)? Is there a more safer way to do a drive upgrade/swap? Cheers, TY in advance. Please feel free to link me to any reading material.

oops, forgot to attach image Please note: my parity isnt checked yet, as im copying over 15TB of data, i will check parity once everything is done copying. Also, i have the 12 drive license, so it shouldnt have anything to do with the license restrictions.

Hey Guys, I just got into Unraid and literally just setup the drives the other day. I added 2 SSDs to my cache pool (1x 120GB Samsung 840 Pro, 1x 240GB samsung 850 Evo). So, after installing the 2 drives, and starting the raid, this is what my screen looks like (refer to attached image). Why does it say 180 GB? Shouldnt it say 360GB (120 + 240)? What am i doing wrong here? Any advice is appreciated. Cheers.

Got my self a dell h310. Now, is there any easy guides i cam follow to get this setup to work with unraid? Or any special terms i should search for when googling? TY in advance.

Any recommendation on how to keep them cool? I have seen some pci slot fans being recommended, do you guys have any specific ones you would recommend me? Also, if there any easy way to monitor the temperature so i can tell what ever im doing is cooling it well or not? ps. my pc has decent air flow, but its decent for a PC not like a server, and air usually doesnt go through the pci slots, so i would need a decent cooling solution.

Is it better? After a quick glance at Ebay, the lowest-ish current pricing i found was (prices include shipping to NZ): AOC-SAS2LP-MV8: 200 NZD => ~140 usd IBM M1015: 125 NZD => ~85 USD Dell H310: 110 NZD => ~75 USD AOC-SASLP-MV8: 80 NZD => ~55 USD Obviously, cheaper the better, but if any of these are significantly better, i can actually afford the highest one on the list. Thoughts?

So that means, either way, the motherboard sata ports are as good if not better than this one. Meaning i should saturate the motherboard ports before the controller ports unless i have a sas HDD or something.

Awesome, i will see if i can purchase it. Also curious, since there will be 8 ports coming out of the raid card, should i be connecting my drives primarily to the raid card or primarily to the motherboard? (ie, should i fill up the raid card before using the sata ports on the mobo, or should i fill up the mobo sata ports before the raid card?). Just not really sure which would be a better for performance. Also, which whould i be plugging in the parity drives, if that matters at all?

Found someone selling a Dell H310 locally. Do i need to worry or check compatibility or anything? Is there any possible issues?

Hey Guys, Im about to join the unRaid train, and i need a way to plug in all my hdds. Amongst them, i have 1x SAS 6tb drive, so i need some sort of a pci extension that can plugin some SAS and SATA drives. Hopefully looking for some cheap/inexpensive option. Can you guys suggest me some? The motherboard im using is: http://www.asrock.com/mb/Intel/Fatal1ty%20H87%20Performance/ Motherboard supports about 6 sata ports, although i will have about 8-10 drives plugged in including ssds (potentially more later). Do you guys have any experiance with something that is good value for money and works easily with unRaid? Preferably < $100? Or, is that too low? At current, the largest drive i will be using will be 8tb Seagate archives, i have 1 6tb dell SAS drive, and several 4tb WD RED's and generic Seagates. Any links to amazon/ebay would be greatly appreciated, hopefully one that can ship to newzealand without a huge cost. Cheers.

Thinking of buying one of these: http://www.cpsww.com.au/Product/Product/GetProduct?id=3 Im assuming this should work with unraid?

Does anyone know if APSUPSD support the UPS Blazer 2000? I suppose not, since its designed for APC. If i somehow get this blazer 2000 (http://www.centralion.com/download/Blazer.pdf), is there any way to get it to work with unRaid do you think?

So, if you have multiple cache drives on your raid (lets say 2x 120gb ssds and 1x 1tb WD Blue), when you are copying some files which of the following is correct: 1. unraid will randomly pick a cache drive and write to that, and when it fills, picks another cache drive and write to that untill all cache drives are filled then it writes to the main raid. 2. unraid write to all cache drives at the same time (to increase write speed). So all the cache drives will be active/spinning (like a typical raid 0?), and you essentially have the write speeds of all non-full cache drives added up. 3. Write to each cache drive, but one at a time (randomly or in some order). ie. writes packet 1 to drive 1, packet 2 to drive 3, packet 3 to drive 1 again etc. 4. you cannot have multiple cache drives, noob.
