Docker/Cache goes Read Only after 1-2 weeks uptime

Featured Replies

I'm having a strange issue where my dockers/cache go R/O after about a week or two uptime. I have my dockers stored exclusively on cache.  My cache drive are 2 Sabrent 2 TB NVME drives setup in a RAID 0 pool. (So, 4tb..) One of them is connected via onboard slot and another is via an addon card.  Everything works fine after stopping and starting the array or reboot. 

Should I just roll with 1 NVME cache drive or change my cache config to have redundancy?  Quick smart tests come back ok. Diags attached.

Btrfs is detecting data corruption:

 

Jan 16 08:50:46 ZEUS kernel: BTRFS info (device nvme0n1p1): bdev /dev/nvme0n1p1 errs: wr 0, rd 0, flush 0, corrupt 52, gen 0
Jan 16 08:50:46 ZEUS kernel: BTRFS info (device nvme0n1p1): bdev /dev/nvme1n1p1 errs: wr 0, rd 0, flush 0, corrupt 56, gen 0

 

This is usually a RAM issue, start by running memtest.

Offfff. Lots of errors. Still running. Does it offer the option to save a log once completed? I'm hoping it is just one stick.

Once it detects one error you can stop, test one DIMM at a time.
