Subject: write time tree block corruption detected
Date: Fri, 17 Jan 2020 03:21:24 -0500 [thread overview]
Message-ID: <5c4a4a6e021fcaf8f608c247a572e95b@bllue.org> (raw)
I've been running 5.4.8 for 10 days and this popped up:
[917767.192190] BTRFS error (device dm-19): block=21374679056384 write
time tree block corruption detected
[917767.193436] BTRFS: error (device dm-19) in btrfs_sync_log:3104:
errno=-5 IO failure
[917767.193438] BTRFS info (device dm-19): forced readonly
This was a btrfs filesystem created on 5.4.8 with two 4kn drives, each
with a single whole disk dm-crypt partition. The fs was created with
mkfs -O no-holes -d single -m raid1 and mounted with
clear_cache,space_cache=v2.
After that issue, I tried to update my backups, but it didn't go very
well:

Fortunately, after a reboot, everything appears healthy, no file
corruption that I can observe, but I'm still running some checks.
I'm not sure what the write tree is or if this is related to the read
tree issues mentioned on the mailing list, any advice/pointers would be
most appreciated. One thing I can note is that I've started to write
heavily to this filesystem via nfs export (the nfs client happens to be
a vm on the same machine, fwiw).
