This is a sample of one of the failures.  Clearly the filesystem gets
created and  the subsequent mount fails because of a copy of files from the
skeleton directory to the expected home directory that basically creates a
file in place of where the system expects a mountpoint directory.

Now this does not happen every time but happens with increasing frequency as
the number of created filesystems increases.  I cannot confirm readily as I
have blown away the pools, but I think I end up with only about 4500
filesystems out of 8200 or so that should be created once the script ends.

Another datum that may be relevant is that the block devices in the pools
are actually iscsi volumes served from several linux openfiler systems over
a private gige network using jumbo frames.

I just updated the system to snv_111a so at some point I'll recreate the
pools and try again, however we are in the middle of a building move so I
might not get to it until later in the week.

I really appreciate any pointers.

Regards, Alastair
