I would guess that your xfsdump inventory is corrupt somehow.
Are you able to do "xfsinvutil -i"? You might also try
"xfsinvutil -C" to do some consistency checks on the inventory.

If none of that works, tar up your current xfsdump inventory
(/var/lib/xfsdump) for a backup, and then remove /var/lib/xfsdump.
You'll have to do level 0 dumps of your filesystems again, but at
least this should get you back to a point where dumps work.

Also, please send me the tar file containing your inventory files.
This could be useful in trying to debug the underlying cause of
the problem you are experiencing.

Dear Bill,

Here is an attempt to get the inventory file:
[bonomo@bob /data]$ sudo /usr/sbin/xfsdump -I > /tmp/xfsinv
xfsdump: inv_stobj.c:1260: stobj_copy_invsess: Assertion `off' failed.
Abort
[bonomo@bob /data]$ cd /
[bonomo@bob /]$ sudo /usr/sbin/xfsdump -I > /tmp/xfsinv
xfsdump: inv_stobj.c:1260: stobj_copy_invsess: Assertion `off' failed.
Abort
[bonomo@bob /]$

The dump command used is:

/usr/sbin/xfsdump -e  -l <level> -f /dev/nst2 <partition to be dumped>

Thank you!

Could you send "xfsdump -I" output as well as the xfsdump command args
that you used? Looks like a problem with the inventory code, or maybe
your xfsdump inventory has become corrupt.

Hello!

Recently, my system (which uses xfsdump 2.2.25
from the Fedora Core 4 distribution) started
failing with this error:

xfsdump: inv_stobj.c:1260: stobj_copy_invsess: Assertion `off' failed.

This occurs immediately after the assignment
(or non-assignment) of a dump label immediately
upon the execution of xfsdump, which halts/crashes/
aborts immediately after reporting the error.

Do you have any idea what would cause such an error?
It seems to have arisen spontaneously, but something
must be causing it.

Thank you.
