environment:
- Red Hat AS 3 (kernel-smp-2.4.21-37.EL - custom built to probe all LUNs
on each SCSI device)
- clumanager 1.2.28
The cluster consists of 2 members running three services which simply
nfs export a number of directories to five other systems.
The cluster has been operational since February.
Following the latest upgrade (from kernel-smp-2.4.21-32.0.1.EL custom
built and clumanager-1.2.26.1-1), all services are running on one
member. When I try to locate the services, the operation fails, and the
following message pops up:
A Problem has occurred while changing ownership
of this service. Please check logs for details.
The cluster log reports the following:

==== end log extract
FWIIW, no one was logged in but me, and my current directory was not on
this filesystem.
Neither fuser nor lsof returned any process using the filesystem.
I figured the clurmtabd process may be locking it, so I did verify that
there is only one clurmtab process for that filesystem.
Any ideas/suggestions?
Kind regards,
Herta
