Hi everybody,
we are using a btrfs RAID 1 with four 2TB hard drives (WD Caviar green
and one Red) on a Debian 7.2 with Kernel 3.12.0
Last week I replaced a broken Harddrive with btrfs replace ...
After that I wanted to balance the filesystem and get a
''Speicherzugriffsfehler'' (Segmentation fault). After that I
want to
reboot the system and nothing happens, it hangs at a btrfs stack trace.
After a hard reset, the filesystem is mounted read only. I don''t know
how to get the filesystem rw ...
