Hey Guys,

Here is the repair log from right after the corruption happened. ÂThe repair was successful.

Oh, ok. ÂThe logprint I'm looking for would have to be taken immediately after
the forced shutdown. ÂSorry for the confusion.

It's great that you have this. ÂAnd an interesting repair log. ÂThe good news
is that it doesn't look like the corruption that xfs_repair doesn't fix, the
bad news is that I don't recognise it. ÂIf you wouldn't mind posting the repair
log to the list, I think that would help. ÂAt least it would get some more eyes
on it.

Thanks much,
