Hello. First off I would like to apologize for my lack of knowledge. While there are some things I know when it comes to PC’s, I don’t know everything. So some of my terminology may not be correct. I’m simply someone who wants to have a simple NAS on a budget. I know very little of linux, and I’m willing to understand more so I can help maintain this system.
I have setup a NAS with a Thinkcentre M910Q. There is a 2.5 SSD where the OS is installed as well as a 1TB m.2 drive installed. That is where my apps, files, and datasets are. The installed apps I have are Nextcloud, Cloudflare Tunnel, Tailscale, and Jellyfin. It’s setup for simple file sharing and media streaming. Not necessarily file backups. Although I hope to expand to something better later, so that I can use this as data backup.
I’m frequency experiencing an issue. Now the first thing I want to mention, is that the M.2 is not being held down properly. And yes, I am already taking measures to try and fix this. The mini PC that I have is not meant for a standoff and screw. I have ordered a plastic push-pin which will be arriving soon and hopefully stop this issue from occurring. And yes, I do realize that this could very well be causing all these errors and what I’m experiencing. I understand that all of this may be redundant given this. I am doing what I can for now, and until I have what I need to properly secure my m.2, here is the issue.
I have alerts setup to my email. Pretty much everyday, I’ll get the error “Pool “my pool name” state is ONLINE: One or more devices has experienced an error resulting in data corruption. Applications may be affected.” Ever since I got the message the first time, I logged into the web UI to see that the CPU averages at high ~95% usage. I would reboot it to see if all of my files were corrupted. Rebooting or shutting down via the web UI wouldn’t do anything. I would forcefully shut it off, reboot, and find that all my files are safe. A notification pops up saying that all of the previous errors have been cleared.
Today that error has occurred multiple times. Seemingly with no cause, not even any heavy work loads. On top of a new error. “Pool “my pool name” state is SUSPENDED: One or more devices are faulted in response to IO failures. The following devices are not healthy: ”My M.2 Drive”.
I ran zpool status -v during one time the error occured with this as the output.
Permanent errors have been detected in the following files:
/var/db/system/update/update.sqsh
/mnt/.ix-apps/app_mounts/jellyfin/config/data/jellyfin.db-shm
Another instance of having and error and running the same command resulted in this:
(Some of the characters are not exact and I apologize for that)

mnt/.ix-apps/app_mounts/jellyfin/config/data/fellyfin.db-shm
But it’s worth nothing that I’ve had the first error happen to me many times without any apps even installed and simply using the SMB service. I have never rain zpool status before today, and it’s my first time noticing the files affected. So I’m confused to see files referenced from jellyfin. It makes me concerned for what the actual problem may be.
It has been a cycle ever since. I have seen a few people online mentioning the possibility of faulty ram. So currently I’m running MemTest86. I have previously loaded my m.2 on a portable drive on my main PC and ran CrystalDiskInfo. The drive was reportedly healthy. Not too entirely sure if only using that software was the right move or conclusive enough to determine that.
