Hi,
I have a btrfs volume in RAID0 across 2 SSDs which has (for no apparent reason)
become corrupted. Although I am able to mount the partition, there are several
messages displayed in the kernel log when doing so.
I have copied the files off the file system, but would like to know if they can
be relied upon or not (and if not, which ones are corrupt). I would also like
to know if the file system itself is recoverable, or should be erased entirely
and replaced.
I have tried 'btrfs check --repair' and btrfs-zero-log to no avail. The SMART
data for both drives suggests there are no issues with the hardware.
Thanks in advance.
