B.7.3 Troubleshooting
Linux does not allow you to umount a volume if any file is currently open. If your system is going
comatose when you try to unload the cluster, it is probably because you have open user connections
and files on the volume. You need to allow enough time for the connections to be closed before the
umount is executed.
Add the following lines between the request to stop service and deleting the IP address:
#stop service otherwise
sleep 10
ignore_error fuser -k /$MOUNT-POINT
sleep 5
Replace
/$MOUNT-POINT
with the actual path of the mount point of your iFolder data store. For
example, if the mount point is
/var/opt/novell/ifolder3/data
, add:
#stop service otherwise
sleep 10
ignore_error fuser -k /var/opt/novell/ifolder3/data
sleep 5
Tune the script until the cluster no longer goes comatose under an operational load when the unload
script is called. If the system goes comatose under a full load, increase the sleept time until the
cluster is able to successfully execute the unload instead of going comatose.
