Re: Kernel error during btrfs balance

[Erik Logtenberg <erik@logtenberg.eu>]

Hi,

Additionally, I cannot mount the filesystem anymore. mount gives no
error messages but hangs in state D.
dmesg shows:
[  422.323116] btrfs: use compression
Which is a good thing, but it doesn't do anything otherwise.

Thanks,

Erik.
