3. Verify that all file system node servers have separate file systems mounted on the following
partitions by using the df command:
• /
• /local
• /stage
• /alt
4. Verify that all FSN servers have a minimum of 4 GB of free/available storage on the /local
partition by using the df command .
5. Verify that all FSN servers are not reporting any partition as 100% full (at least 5% free space)
by using the df command .
6. Note any custom tuning parameters, such as file system mount options. When the upgrade is
complete, you can reapply the parameters.
7. 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 all nodes hosting the passive Fusion Manager, place the Fusion Manager into maintenance
mode:
<ibrixhome>/bin/ibrix_fm -m nofmfailover
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 9000 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.
