Hi,
I'm not sure whether it's a bug in btrfs or my distro but I discovered
an odd behavior today.
My Setup:
* Btrfs v3.12+20131125
* /dev/sda – Boot OS - opensuse 13.1
* Btrfs RAID 1 on /dev/sdb1 and /dev/sdc1
I added an extra HDD with an other OS and Data on it witch accidentally
became /dev/sdc.
Btrfs got mounted at boot time without any complains but in the main
volume was empty.
Some subvolumes still had Data.
I took the extra HDD out but still no data in the Btrfs main volume.
Bfrfsck reported no error.
Some Parts on the (accidentally) /dev/sdc are now corrupt.
I would expect that btrfs would throw an error when getting in the kind
of scenario.
Regards
Ingo
