Re: btrfs balance enospc

[Mark Murawski <markm-lists@intellasoft.net>]

The smart stats on the disk are fine.  The /dev/sdc messages are from me 
playing around and pulling out the drive.   btrfs fi show, shows the 
drive as missing, yet it's still trying to write to it.

Basically my goal is to remove this drive and stick it in another box 
and I can't get btrfs to move all the data off of it due to enospc.

I'm gonna try and move some data off and remove/balance again.

probably not why you're getting this failure.
