Great, I think I just needed the affirmations to tell me this isnt raid, relax, its unraid! Thank you all for sharing!!!

Hello, I come from a background of using raid prior to unraid. I know that Unraid is not raid, but with hard drives getting more "dense" raid-5 is practically obsolete due to hard drive densities and the odds of a URE during reconstruction, and many articles I've read are showing that raid-6 is heading in the same direction. I do understand that Unraid is not raid, and that it has a different way of "handling" these issues during a reconstruction if a drive was to catastrophically fail, and require a rebuild. So I guess my question is, outside of reliability of the drives in general, unraid handles URE's by simply lets say "skipping" over them during the reconstruction correct? I shouldnt really be worried about GB density with these newer drives as technically a URE during a rebuild would not cause a complete loss, but still allow recovery/reconstruction of the pool to a protected state even with some potential corrupt or unreadable data was found during a reconstruction? Has anyone here rebuilt from a parity or pool of 8TBs? What was your experience? I'm just looking at getting into 8TB drives on dual parity (im currently on single parity 4tb wd reds), and my case is starting to get full, and I need to expand, and would just like some more insight and if I really shouldnt worry so much about encountering a URE during a reconstruction with such dense drives. Thank you all for any answers you can provide, and taking the time to read this.

I know that feel, I'm a web developer myself. Thats why I offered to update that portion for you Just thought I'd offer. Thanks for your response. I got everything I needed going!!! cAdviser rocks. (So does your app!)

Thank you so much, I just read in the documentation that installing cAdvisor is recommended. You may want to amend your Documentation, as its still implied that there is a resource monitor in the application. I'd be happy to submit a pull request if you have a github for an update to the documentation.

Hi, I love the application, but I am having an issue, every where that I see a tutorial or a screenshot of the CA, there is a "resource monitor" button that is available on the upper right hand corner, my CA does not have it. I have tried re-installing multiple times and checking my settings and my CA does not look like the screenshots I have seen. Is there some hidden setting somewhere that I am missing? I really need to get to the resource monitor!

Hi all. I finally got around to pulling the trigger on my first unraid/home server. The goal of this build was to fulfill the following criteria: Run an ungodly amount of dockers 1 linux VM for my databases Hold 10 drives total Plex Redundancy Smallest package possible Parts list: Fractal Design Define Mini Black Silent MATX Mini Tower Computer Case SUPERMICRO MBD-X11SSM-F-O Micro ATX Server Motherboard LGA 1151 Intel C236 EVGA SuperNOVA 650 G2 220-G2-0650-Y1 80+ GOLD 650W Fully Modular EVGA ECO Mode Includes FREE Power On Self ... ICY DOCK 2 x 2.5" SATA/SAS HDD/SSD to 5.25" Hot Swap Mobile Rack Cage w/ 3.5" Drive/Device Bay- ExpressCage ...

Ah, this is the beauty of the smallest form with most drives. I searched tirelessly to fall upon the case I chose. It can hold 6 drives internally, and with the ICYDOCK hotswap cage, I have my two mirrored cache drives in it. That cage can hold 1 more HDD, along with the 5.25 at the top for a total of 8 full size HDDS + 2SSDs!!! I am currently in the process of pre-clearing the 3 drives im starting with. 2 drives + 1 parity. Hopefully they go off without issue. I can officially become the data hoarder I've always dreamed about. I just wanted to post this completed builds so I could get your comments/thoughts, and also just give reference for anyone trying to accomplish the same goals as I listed above. The build went absolutely smooth and went off without a hitch. Thank you all for the wealth of information here on the forums. Couldn't have done it without you!

Thank you everyone for your help. I believe that answers all of my questions.

Ok then I will be getting a SSD to use as a cache drive. I guess the LAST question I would have for this is about torrenting. After reading more on the forum, I'm looking at the WD 2TB Reds (5400RPM) instead of the 7200 Seagates. If I set up sickrage/rtorrent to do its job of finding the torrents and downloading etc, to my understanding it will exclusively use the cache drive to do all of its operations, and then move everything off the cache to the actual raid. Is this correct? The reason I ask this is I read that using low speed drives as the destination for torrent activity and other drive activity can hamper or cause issues with the torrents speed. Will getting an SSD cache alleviate this problem?

After looking at possibly upgrading to a Xeon (so that I can still get ECC support) didn't seem worth the extra money just to run a windows VM if I can run all of my services in dockers to have full access to the hardware. I have had experience using dockers in other applications so I would not be afraid in using these. You mentioned that dockers are by default installed to the cache drive. I'm planning on using 7200RPM Seagate Constellation 2TB drives, is a cache drive absolutely necessary to use the dockers? Or can I just use the raid array. I plan on having 16GB of ram in the machine, and from what I have read, RAM is used to cache the data that is being written and then once that is full the write rates will slow down (not a big deal to me, I can always find an SSD and throw it in later). My main use for this is to schedule torrenting while im asleep over a proxy, and to serve up to 2 1080p streams transcode at a time (90% of the time it will be 1 transcode stream), otherwise its just gonna be a data dump for my awful data hoarding habit. Passmark scores and the information from plex state that the i3 should be more than sufficient for my needs. Are there any recommendations you could give to this build given my use-case?

Hello all, I am in the process of building my first home NAS, and I have decided to go with Unraid. I plan on building with a Skylake I3-6300 on a SUPERMICRO MBD-X11SSM mobo with ECC Ram. The reason I really want Unraid is because of the ability to have Unraid manage the underlying storage, and to run a windows VM over it so I can configure Utorrent, Sickrage, couch potato and Plex (in an environment i'm familiar with). I have a couple questions that researching youtube/Unraid website has not clearly answered. When I provision a windows VM, my i3 will have 4 cores to assign to the windows vm (2/2), Do i have to leave a core open for the underlying UnRaid OS to operate? Meaning will I have to assign less than 4 cores to my windows VM that it will be running? (I dont plan on running any other VMs on the box). If i can assign all 4 cores to the VM will it degrade the throughput and write speeds to the provisioned storage pools that Unraid is managing? I don't want to over-provision my windows box where all the heavy lifting takes place and then choke out the underlying OS (unraid) from doing its job. Is this a valid concern? Also, I will be running on a gigabit network, will an SSD write cache be needed to saturate the gigabit network? I plan on starting with 5 HDDS with 2 as parity, will I be able to just throw another hard drive in and expand the pool? My understanding in freenas is that i would have to destroy the entire pool and reprovision it with the new HD addition. I have money burning a hole in my pocket and if I can get these questions answered I'm ready to pull the trigger on my build!! Thank you all in advance for your time!
