After a recent kernel upgrade TSM (Tivoli Storage Manager) running
under the Linux emulation of FreeBSD suddently stopped working. Whenever I start the client I end up with the following error messages:

ANS1228E Sending of object '/TSM-Backup/var' failed
ANS1063E The specified path is not a valid file system or logical volume name.

On the web I found indications that others are having problems too - see

There I found a post by Paul Mather from August 2006 (!) describing the exact same problems under 7-CURRENT that I'm now facing under 6-STABLE.

So I contacted Paul and he informed me that a patch went in for FreeBSD 6 by August 2007 that could be the reason for my problems:

Looks like the implementation formerly under 7-CURRENT has been back-ported to 6-STABLE (?)

I've already contacted Boris Samorodov (bsam <at>> and Alexander Leidinger (netchild <at> who advised me to file a PR.

To further track things down I tried with different versions of the
kernel sourcecode, i.e. cvs-ing sources with "*default date=..." -
here is what I found out:

Kernel sources as per				TSM running?
Original Installation CD			yes
2007.				yes
2007.				yes
2007.				yes
2007.				NO
today						NO

So it seems that a kernel change done between August 25 and September
1 2007 is the cause of the problem.

Please note that nothing else has been changed on the system - only
the kernel has been upgraded. Also note that I've been using TSM under
FreeBSD for years starting with 5.x and now at 6.2 without any
problems whatsoever.


Problem is 100% reproducible.
