Hello,
While my btrfs mounts ok on several instances of my home OpenElec, but
on ArchLinux it fails with:
[174828.954975] BTRFS error (device sdc): super_num_devices 3 mismatch
with num_devices 2 found here
[174828.956969] BTRFS error (device sdc): failed to read chunk tree: -22
Note that it never had 3 volumes! Same happens with -o degraded:
[174828.860334] BTRFS info (device sdc): allowing degraded mounts
[174828.860352] BTRFS info (device sdc): disk space caching is enabled
