January 5, 20251 yr Hey! I went into my logs I noticed that I have some btrfs warnings and errors: Tower kernel: BTRFS warning (device sdb1): csum failed root 5 ino 163757 off 66686275584 csum 0x84377818 expected csum 0xe7761fe4 mirror 1 Tower kernel: BTRFS error (device sdb1): bdev /dev/sdb1 errs: wr 0, rd 0, flush 0, corrupt 1, gen 0 It seems like the issue started on november 14 and I really don't know where to start. Failing drive? Faulty memory? Can I get some pointers? (The drive is 1 year old, only written about 60 tb, rated for 2500). I don't know if it's related, but october 18 I got help to get my fs going again by copying all of the data and then reformat my cache-drive: tower-diagnostics-20250105-1011.zip Edited January 5, 20251 yr by Pedrofranken
January 5, 20251 yr Community Expert Solution Btrfs is detecting data corruption, also see some segfaults, start by running memtest.
