Stop all client I/O to the cluster or file systems. On the Linux client, use
lsof </mountpoint>
to show open files belonging to active processes.
8.
On the active Fusion Manager, enter the following command to place the Fusion Manager
into maintenance mode:
<ibrixhome>/bin/ibrix_fm -m nofmfailover -P -A
9.
On the active Fusion Manager node, disable automated failover on all file serving nodes:
<ibrixhome>/bin/ibrix_server -m -U
10. Run the following command to verify that automated failover is off. In the output, the HA column
should display
off
.
<ibrixhome>/bin/ibrix_server -l
11. Unmount file systems on Linux StoreAll clients:
ibrix_umount -f MOUNTPOINT
12. Stop the SMB, NFS and NDMP services on all nodes. Run the following commands on the
node hosting the active Fusion Manager:
ibrix_server -s -t cifs -c stop
nl
ibrix_server -s -t nfs -c stop
nl
ibrix_server -s -t ndmp -c stop
If you are using SMB, verify that all likewise services are down on all file serving nodes:
ps -ef | grep likewise
Use
kill -9
to stop any likewise services that are still running.
If you are using NFS, verify that all NFS processes are stopped:
ps -ef | grep nfs
If necessary, use the following command to stop NFS services:
/etc/init.d/nfs stop
Use
kill -9
to stop any NFS processes that are still running.
If necessary, run the following command on all nodes to find any open file handles for the
mounted file systems:
lsof </mountpoint>
Use
kill -9
to stop any processes that still have open file handles on the file systems.
13. Unmount each file system manually:
ibrix_umount -f FSNAME
Wait up to 15 minutes for the file systems to unmount.
Troubleshoot any issues with unmounting file systems before proceeding with the upgrade.
