repeatable bug in xfsdump - dumps overwritten on tape

["Jeremy Jackson" <jerj@xxxxxxxxxxxx>]

Hi,

I think I've found the problem with xfsdump.  2.2.14 when used on completely
different hardware (IBM Netfinity - 20GB Seagate DAT) has the same problem.
2.2.11 does not.  Looking at the changelog, I see a "fix" for multiple dumps
on the same tape in 2.2.13.  This fix appears to allow infinite dumps onto
one tape, however only the first one and the last one are permanent ;-<.

This is a pretty serious regression.  It munges your backups and you won't
find out until you try to restore.

Cheers,

Jeremy Jackson
