Hello everyone,

 

I've been experiencing weird failures of my Unraid server. There would be these sudden shutdowns maybe once a month. I set up the syslog server, but no shutdown events are recorded.

Suddenly I noticed that when I tried to make changes to the dockers, I would get: "Execution error 403". This would not get fixed with a reboot. The next day my cache drive showed as unmountable, with the error: "Unmountable: Unsupported or no file system"

 

As of this moment, I don't have access to my cache, the cache drive showed corruption, the parity is showing as valid (checked just a couple days ago).

 

Running Unraid 6.12.6

 

Things I've tried:

Ran memtest86 3 times on the RAM, which resulted in FAILED every time.

Used the command: "btrfs dev stats /mnt/cache" which showed 1 corruption error.

Tried rebooting several times, no changes.

Tried unassigning and reassigning the pool and reboot.

Used the command: "btrfs rescue zero-log /dev/nvme0n1" which failed.

 

I do have the "appdata" folder backed up.

 

I will RMA the RAM sticks, but was wondering if there's anything else I should also do here. Any and all tips appreciated

That means any data written is suspect, as it all flows through RAM. Likely all the recovery attempts while the bad RAM was installed caused more issues and corruption. When the machine can pass a long memtest, preferably more than 24 hours, then you can start recovery efforts.
