Hi,
2 days ago our server was frozen.
Can anyone tell me what happened with my btrfs?
Should I create a bug report or is this a known issue?
Our specifications are:
- kernel version: 3.15.2
- distribution: debian 7.5
- 2 btrfs-pools (RAID 1) with 2x3TB and 4x2TB
we get the first error messages at 22:48:
