Description Robert Rati 2012-03-05 15:19:24 UTC

Description of problem:
I manually mounted a NFS export at a different mountpoint (/mnt/condor-qsjs) than was in the cluster.conf, and for a different reason, and the netfs RA refused to mount the export when it tried to start the cluster service.  The logs showed:

[netfs] Device 192.168.122.176:/opt/condor is mounted on /mnt/condor-qsjs instead of /mnt/condor-schedd1
unmounting /mnt/condor-schedd1
[netfs] Calling 'umount -f /mnt/condor-schedd1'
[netfs] Sending SIGTERM to processes on /mnt/condor-schedd1
