m0t0rh3ad Posted May 30, 2021 Share Posted May 30, 2021 Hello, I've got errors that I can't resolve on my Cache pool (2xSSD Raid1). Errors from server's console - attached screenshots When I've tried to check filesystem placing pool in Maintenance Mod, I've got a lot of such messages: checksum verify failed on 4141940736 found 000000E6 wanted FFFFFFB5 checksum verify failed on 4141940736 found 000000E6 wanted FFFFFFB5 checksum verify failed on 4141940736 found 000000E6 wanted FFFFFFB5 Csum didn't match owner ref check failed [4141940736 16384] ref mismatch on [46354452480 12288] extent item 1, found 0 incorrect local backref count on 46354452480 root 5 owner 304198 offset 0 found 0 wanted 1 back 0x2776150 backref disk bytenr does not match extent record, bytenr=46354452480, ref bytenr=0 backpointer mismatch on [46354452480 12288] owner ref check failed [46354452480 12288] ref mismatch on [46458929152 32768] extent item 1, found 0 incorrect local backref count on 46458929152 root 5 owner 304202 offset 0 found 0 wanted 1 back 0x2134640 backref disk bytenr does not match extent record, bytenr=46458929152, ref bytenr=0 backpointer mismatch on [46458929152 32768] owner ref check failed [46458929152 32768] ref mismatch on [46459015168 53248] extent item 1, found 0 incorrect local backref count on 46459015168 root 5 owner 304213 offset 0 found 0 wanted 1 back 0x21348a0 backref disk bytenr does not match extent record, bytenr=46459015168, ref bytenr=0 backpointer mismatch on [46459015168 53248] owner ref check failed [46459015168 53248] ref mismatch on [46459699200 53248] extent item 1, found 0 incorrect local backref count on 46459699200 root 5 owner 304215 offset 0 found 0 wanted 1 back 0x21356e0 backref disk bytenr does not match extent record, bytenr=46459699200, ref bytenr=0 backpointer mismatch on [46459699200 53248] owner ref check failed [46459699200 53248] Please suggest something to fix these errors.

m0t0rh3ad Posted May 30, 2021 Author Share Posted May 30, 2021 Tried to use command btrfs check --repair /dev/sdk1 got a lot of messages like repairing missing dir index item for inode 1137979 then Trying to rebuild inode:304201 Moving file 'chapter4.jpg' to 'lost+found' dir since it has no valid backref and i hope right now everything will be fine because btrfs scrub status: Error summary: no errors found PS If I should do anything else please write down, thanks Quote Link to comment
JorgeB Posted May 31, 2021 Share Posted May 31, 2021 There's uncorrectable metadata corruption on the pool, you need to backup and re-format it, there are some recovery options here if needed. Quote Link to comment
6of6 Posted June 1, 2021 Share Posted June 1, 2021 Drives fail. I thought I was smart having 2x500Gb SSD for Cache. I think I'll go 1x500Gb for cache and 500Gb backup after reading this. 6. Quote Link to comment
