panic BTRFS error (device sdp) in __btrfs_inc_extent_ref:1935: Object already exists [Linux 3.8.4]
Hi all,
I tried to replace a failed device in a btrfs filesystem on Linux kernel 3.8.4.
After adding a new harddisk (/dev/sdf) to the btrfs pool and removing
the failed device with "btrfs device delete missing /btrfs" the server
panicked.
We can still mount the filesystem in degraded mode, what are the
options to resolve this :) ?
