The issue is the snapraid process is trying to create a lockfile in /var and your user doesn't have permissions to write there. You could chown those files to your user and get past that error message. Some underlying commands like snapraid smart won't work without elevated permissions.

It's a permissions error. Are you trying to run snapraid as a non-root user (your user probably doesn't have permissions to write to /var)?

The one person that tried to help, you crapped on. No one else has documented it so far. Try it yourself, and share your findings.

Since this is a new build, have you run a memtest on the RAM to confirm that it's working properly? Faulty memory can cause all sorts of errors like these.
-
Great news! I am happy to help. Good luck on your journey to learning more about the great combination of SnapRAID and mergerfs!

This is an issue with your create mode in mergerfs, and is not related to SnapRAID. Since you didn't define a create policy in your mergerfs mount line in /etc/fstab, it is defaulting to a path perserving create mode. I would suggest you umount /mnt/storage, then add this to your mergerfs mountpoint in fstab. This is not path perserving and will use the disk with the most free space. category.create=mfs Then, remount. Since you already have moveonenospc enabled, that should be all that it takes to...

Just wanted to interject into this thread quickly. UhClem, the time and effort you have put in to support Allan is incredible. People don't get paid support as competent and thorough as you have been giving. Well done!
-
Hmm... Leifi really knows SnapRAID, so I wouldn't want to contradict previous advice that appears to have worked, because Andrea even contributed to the conversation. I've never done a restore like this, so I can't speak to it. I know that replacing the disk works as I've done that a few times over the years.
-
Hello :) You can't perform a restore to an existing disk in your array (meaning you can't name the same disk twice like /mnt/data/disk18 in this case). You will need to replace disk d05 with a new, formatted, and mounted disk to properly perform this restore. I'm honestly surprised it even let you do this in the first place without throwing an error (I guess it threw 18 files worth of errors). I wish I had a cheaper answer (I hope you have an extra disk or two at home), but put in a new disk, and...

You just need to download the latest tar, unzip and install. This should do it. Please make sure that after you run make check that it says it completed with no errors before you run the make install command. sudo -i wget https://github.com/amadvance/snapraid/releases/download/v11.3/snapraid-11.3.tar.gz tar xzvf snapraid-11.3.tar.gz cd snapraid-11.3/ ./configure make make check make install You can verify that it updated like this. snapraid -V I hope that helps.

-
Can you provide the exact error? That sounds like just a standard SMART error alert. SnapRAID only works on the disks that are mentioned in your snapraid.conf file.
-
It is impressive, but you can do it pretty easily with enterprise hardware. Either buy a SAS can with external ports and use a JBOD chassis or just buy one server that can hold 45 or 60 drives. There are actually a lot of solutions that accomplish this. Here is one example of many :) https://www.ebay.co.uk/p/HGST-60-Bay-4u-Sas3-JBOD-LSI-HBA-QSFP-to-Mini-SAS-Cable-High-Density-Storage/4007757229?thm=1500
-
This is correct. All of my HGST He6/8 SAS/SATA drives can each read and write over 200MB/s. That is the disks' limitations, not the controller. With 8 SSDs attached, you could max the controller out.
-
Power draw would be the main reason to upgrade. That will draw alot of watts just idling, and 24/7 x whatever you pay per kWh, can add up quickly. Also processing power, if you plan on using this for anything other than just a fileserver (Emby, Plex, etc.). The E5410 only has a passmark score of 3272, which is very lame by modern standards. Another issue is PCIe bus speed. That era of CPU and motherboard only supports PCIe 1.0. So, it is servicable, but you will likely want to upgrade in the near...
-
I use (3) Dell H310 controllers flashed to IT mode. These are all PCIe x8 controllers and support 6Gpbs per disk x 8 disks per controller. What's equally important is the disk that is hooked up to the controller. I use a mix of 6 and 8TB HGST He Ultrastar disks (some SAS, some SATA) that can all read well in excess of 200MB/s each in real world use (not synthetic benchmarks or small dd reads/writes).
-
It looks like a decent deal. That hardware is very old (CPU, motherboard, RAID controller, RAM), but the case, SAS2 backplane, and two platinum PSUs are all very nice. Since barebones 846's with SAS2 backplanes seem to be around $399 (US eBay) without drive caddies and with less efficient PSU's I think it's a pretty good deal. I'd see if I could negotiate with the seller them knocking off at least $50 and they can keep all the old parts and just sell you the case and PSUs. They almost certainly will...
-
As Andrea mentioned, I have all my disks connected via SATA controllers. I see typically around 1,900 MB/s when all my disks are involved (21 data disks and 3 parity disks).
-
I use the Norco 4224 at home and the Supermicro SC846 at the datacenter. The Norco's build quality is not as robust as the Supermicro, but it is WAY easier to make quiet which is a big factor for home use. I picked mine up when they were selling new for $299. If you go the Supermicro route, make sure you buy either a TQ model or one with a SAS2 backplane (BPN-SAS2-846EL1) if you want to support disks larger than 2TB.

Hello, Please try again on the form (Contact Form 7 needed an update. Or, if it's a question about a particular post, please ask the question there. That way others can benefit from your question and any resulting conversation. Thanks!

lol. Curse this old brain of mine.

Thanks! That's how I "assumed" it worked, but I didn't want to assume :)
-
Hello, I have a array with dual parity using (2) 4TB disks for each parity level. The data disks are all 8TB disks. I have picked up a couple of new 8TB disks, and I would like to use these for my parity disks instead. Can I easily switch back to single parity disks, or do I need to rebuild. I'm doing this, becuase I need to free up the two additional bays in my 24 bay case for some extra disks. Thanks!
-
Good! I was afraid I was going to come off as a jerk. I totally understand the money component. You already have a case, so why change? I would definitely consider buying some new SATA power splitters as those molded ones have been known to cause some nasty fires.
-
That's creative, but the two loss disks and the mass of cables is terrifying to me. Hopefully, you aren't using molded SATA power splitters(risk of fire). Those splitters look like they are molded. Here's how to indentify them https://www.youtube.com/watch?v=TataDaUNEFc You've spent lots of money on hardware, so why not spend money on a proper 24 bay, hot swappable case? I picked up my two Norco 4224's for $199/each. You can run three 120mm fans in the fan wall, and everything connects with 8087...

Well, I'm glad those articles were helpful :) Although, I understand your concern for having space for the content file(s), as you mentioned, the minfreespace option is your savior with minimal effort. Just set it to 20GB+ and you will always have space for your ~2GB content files.
-
I just create one large partition on my data disks. This disks will also contain the content files. I see no reason to use LVM in a SnapRAID + mergerfs scenario. I think it just adds complexity. I have directions on my site to setup SnapRAID and mergerFS if you are interested. https://zackreed.me/setting-up-snapraid-on-ubuntu/ https://zackreed.me/mergerfs-another-good-option-to-pool-your-snapraid-disks/

Or if you use Docker, you can build it and then completely clean up afterwards without installing build tools on thehost https://github.com/IronicBadger/docker-snapraid

Does SnapRAID require "real hardware" access to function, probably not (although, things like drive spindown, SMART, etc. won't work without it). If you are going to virtualize your NAS, I would definitly suggest passing through an HBA(s) to your Ubuntu VM. I have personally used both ESXi and Proxmox in this exact scenario with Ubuntu VMs with SnapRAID and both worked well. I personally love Proxmox for my home hypervisor. It's free, simple to use, and has a nice Web GUI built-in, and provides a...
-
Your SMART data looks clean, and you have no UDMA errors, so it's not a cable. I didn't understand it was the same file every time causing this issue. That would typically mean that something is accessing it during a sync causing it to appear to be changed. What type of file is it? Have you tried moving it out of the array and syncing (removing it from SnapRAID), then move it back and re-sync?
-
What does a full smartctl tell you about the disk? This sounds like either a failing disk, bad cable, or backplane (if you have backplanes). smartctl -a /dev/sdl
