BTRFS critical (device loop2): corrupt leaf

[RodWorks]

Good morning, getting this error which has kept my docker from loading.  Appreciate any help.

Docker image is corrupt, delete and recreate, possibly caused by one of the pool devices dropping offline:

Aug 23 10:20:40 Unraid kernel: BTRFS info (device sdd1): bdev /dev/sde1 errs: wr 6575101, rd 13546, flush 121230, corrupt 0, gen 0

See here for more info and better pool monitoring.

root@Unraid:~# btrfs dev stats /mnt/cache
[/dev/sdd1].write_io_errs    0
[/dev/sdd1].read_io_errs     0
[/dev/sdd1].flush_io_errs    0
[/dev/sdd1].corruption_errs  0
[/dev/sdd1].generation_errs  0
[/dev/sde1].write_io_errs    6575101
[/dev/sde1].read_io_errs     13546
[/dev/sde1].flush_io_errs    121230
[/dev/sde1].corruption_errs  0
[/dev/sde1].generation_errs  0

 

so is this a pool cache failing?  Or just do the delete and recreate and check after that?

It means one of the devices dropped offline in the past, not necessarily that it's failing, most often it's a power/connection problem.

Copy that, thank you for your time and advice.  Everything is up and running again!
