There was one person that complained about fsck on gjournal but not in
the same context - he created the journal for gjournal on an existing
file system and so destroyed a part of the data. I don't think this is
related to your case.

Does gjournal complain about your drive, for example that it doesn't
support BIOFLUSH?

Also, did fsck actually do something when it was started (did it find
anything corrupted)?
