_vern_ Posted May 22, 2021 Share Posted May 22, 2021 Hoping someone can provide some assistance with a BTRFS Scrub issue that I'm having. I noticed some errors in my log, sample below... Apr 29 03:14:55 Media-Server kernel: BTRFS warning (device sdj1): csum failed root 5 ino 545882 off 86016 csum 0x3270ca11 expected csum 0x28eadb3e mirror 1 Apr 29 03:14:55 Media-Server kernel: BTRFS error (device sdj1): bdev /dev/sdj1 errs: wr 0, rd 0, flush 0, corrupt 199, gen 0 Apr 29 03:14:55 Media-Server kernel: BTRFS warning (device sdj1): csum failed root 5 ino 545882 off 86016 csum 0x3270ca11 expected csum 0x28eadb3e mirror 1 Apr 29 03:14:55 Media-Server kernel: BTRFS error (device sdj1): bdev /dev/sdj1 errs: wr 0, rd 0, flush 0, corrupt 200, gen 0 I then ran the BTRFS Scrub and I get the following... UUID: 5b75a579-d759-43e6-809d-37b296dce574 Scrub started: Sat May 22 12:28:47 2021 Status: finished Duration: 0:06:15 Total to scrub: 173.01GiB Rate: 472.50MiB/s Error summary: csum=3 Corrected: 0 Uncorrectable: 3 Unverified: 0 DMESG does identify a file that appears to be the offender, but it's buried deep in PLEX docker and everything I have tried with it just keep showing the issue when I run Scrub. When I run btrfs dev stats /mnt/cache I get the following...I had reset the stats...it previously stated 315 corruption errors. [/dev/sdj1].write_io_errs 0 [/dev/sdj1].read_io_errs 0 [/dev/sdj1].flush_io_errs 0 [/dev/sdj1].corruption_errs 3 [/dev/sdj1].generation_errs 0 Is there a prescribed method for correcting this issue? Thanx! Quote Link to comment
_vern_ Posted May 23, 2021 Author Share Posted May 23, 2021 I probably should have added that this is occurring on my cache drive and that it's an SSD. Any suggestions on how to correct? Thanx! Quote Link to comment
