Going to mark this as solved - I ended up re-creating the cache pool as zfs, as I'd intended to do that for awhile anyway. Have daily backups for the Home Assistant vm, so that was easy to redeploy. Docker containers were easy to bring back as well, since the config stuff is saved (on the flash storage, I think?) Did some more cleanup also, seemed like a good time. Scrub'd and ran SMART tests. I'll still run memtest86, I just haven't dragged a monitor down to the unRaid server - but I shall. Appreciate your assistance @JorgeB - not just with this particular incident, but many of the threads I've referenced for all sorts of questions I've had with unRaid end with you providing a solution. ...I do very much hope to avoid having to reference this forum for at least a few weeks

Thought maybe it was going to last... Was still functioning around 04:00 03:00 and then by 06:00 the problem reappeared. New logs attached - I do see a ton of BTRFS errors begin right at 03:00 in the logs. 03:00 is the time the appdata backup runs. unraidy-diagnostics-20241210-0635.zip

Roger that. I'll post logs in the AM if the problem occurs again tonight. I've updated the docker containers, removed a few containers I'm not using, updated the OS, and run smart tests on the two nvme drives. Everything running great at the moment.

Recreated the pool yesterday, and same result this morning. Any further suggestions that might solve the problem?

@JorgeB and sure enough it's happened again. Attached the log in case there's anything notably different than yesterday's case. Is there a reason why the redundancy of the 2nd drive isn't allowing for things to move ahead? Should I pull the 2nd ssd and use it elsewhere? Will plan to rebuild cache pool. adding: rebuilt cache pool, will report back (or mark as solved) in 24hrs or so, when it seems the issue is unlikely to repeat. unraidy-diagnostics-20241208-0721.zip

So after looking at the logs, it seemed like running btrfs rescue zero-log /dev/nvme0n1p1 In the terminal was a good step to take, given some browsing on this forum. I then restarted the array, and things look okay. My only questions are: how might this have happenened, and should I be doing something to prevent it in the future?

Good day yall, Noticed my home assistant instance not functioning this morning, so opened up the Unraid UI and found that my brfs cache pool was reporting "Unmountable: Unsupported or no file system". I have two Samsung nvme drives in a raid1 (see attached photo). I don't think I've made changes to the server recently, although perhaps I'm forgetting... If anyone has ideas on steps to try to fix I'd very much appreciate it. unraidy-diagnostics-20241207-1555.zip

Ugh, yes, I'm a bonehead. Thank you. I must've been messing around at some point, and had changed the torrent app to look directly at cache. Much appreciated!

It's happened again - I'm assuming it's happening during the nightly mover action? Checked the server this morning, and the directory structure on cache_ssd is gone. This drive serves as a download location until the files get moved to the array overnight. This must be some sort of user error, as I'm new to unRaid, but I did follow the TRaSH guides for setting up this directory structure. Attaching diagnostics file. Appreciate any insights! tower-diagnostics-20240714-0753.zip

Followed the TRaSH guides to setup my media server, was working great for about a week. Yesterday I decided to purge some files from Qbittorrent, and deleted the contents of the /data/torrent/tv and /data/torrents/movies folder. Today I looked at qbittorrent and all the new downloads were errored, and came to realize the folders on my cache drive are seemingly gone? They seem to show up if I access the smb share via Windows file explorer, but if I open the cache drive from within the unRaid GUI the folders are not there. Files on the array are intact, with no-issues as far as I can tell. Any idea the easiest way to re-add the missing directories? I'm worried I'm going to do something impulsive that'll screw up the existing files on the array. Any thoughts much appreciated.

Have a new unRaid build going, and my processor is struggling when downloading using this container. Admittedly, this processor is a lowly n5105, so if this sort of performance is to be expected, then I'll learn to live with it (for now...). When downloading 5 torrents, the cpu usage is around 40-90%. I'm using wireguard, although I did attempt using openVPN beforehand with similar results. Thank you for any insights, much appreciated.
