March 25, 20215 yr ~10 days after I had the previous BTRFS cache drive corruption I just ran into the same thing. Beyond me trying to replace the NVME drive, any other suggestions? It seems like the issue starts after heavy NVME loads.... ie. I copied ~700gigs worth of file to NVME then deleted then shortly a few hours later.... Copying was done around 15:30 (see log) tower disconnected from "PC-LAN" (9d 4h 48m connected, 31.3 GB)11:09 pm 03/23/2021 (from Uqibiti log) Diagnostics are from 14th after I reformatted cache drive last time. I can power cycle, as right now the server is on the screen as in the picture. Last time I ran full hardware diagnostics to include memtest86. Found no issues. Advice, suggestions.. anything at this point as it is driving me crazy, lol. syslog tower-diagnostics-20210314-0853.zip
March 25, 20215 yr Community Expert Reoccurring filesystem corruption without an apparent reason suggests an underlying hardware issue, start by running memtest.

I think the 1st time (2 weeks ago) I ran the memory testing from the unraid flash drive boot. Just created a fresh Memtest86 USB and running a new test now. Also, this issue occurred when I was watching something on Plex with my phone. I had it set to play Original quality so no transcoding. Only changes I did this year were adding PiHole docker sometime in February. (Plex, SABnbzd, Sonarr only other dockers) Since last cache drive format I did the following: PLEX TRASNCODING TO RAM https://forums.unraid.net/topic/35878-plex-guide-to-moving-transcoding-to-ram/page/12/ mount -o remount,size=20G /dev/shm Beyond that server is mainly for storage. Never more than 2 streams and that's very rare. All activity is local.
April 16, 20215 yr Author Update. Replaced NVME HD and have been up for 19 day until today's crash/freeze. No corruption. syslog (4) tower-diagnostics-20210416-1744.zip
June 11, 20215 yr Author Just an update on this issue. Took a lot of testing..... didn't help that my son yanked the power cord out so I had to run stability check again. Either way I was over 30 days with no any kind of BTRFS corruption or other issues.... (well, besides the version not available for dockers...) The only thing I shut off is the pihole template docker that was residing on my appdata folder on my NVME. I haven't brought it up there since I don't really need it and was only testing. So.., leaving this here just in case somebody runs into this weird issue.
