File system unmount issues
If a file system does not unmount successfully, perform the following steps on all servers:
1. Run the following commands:
chkconfig ibrix_server off
chkconfig ibrix_ndmp off
chkconfig ibrix_fusionmanager off
2. Reboot all servers.
3. Run the following commands to move the services back to the on state. The commands do not
start the services.
chkconfig ibrix_server on
chkconfig ibrix_ndmp on
chkconfig ibrix_fusionmanager on
4. Unmount the file systems and continue with the upgrade procedure.
Upgrading the StoreAll software to the 5.6 release
This section describes how to upgrade to the latest StoreAll software release. The management
console and all file serving nodes must be upgraded to the new release at the same time.
Upgrades to the StoreAll software 5.6 release are supported for systems currently running StoreAll
software 5.5.x. If your system is running an earlier release, first upgrade to the 5.5 release, and
then upgrade to 5.6. The upgrade procedure upgrades the operating system to Red Hat Enterprise
Linux 5.5.
IMPORTANT:
• Ensure that the NFS exports option subtree_check is the default export option for every
NFS export. See “Common issue across all upgrades from StoreAll 5.x” (page 154) for more
information.
• Do not start new remote replication jobs while a cluster upgrade is in progress. If replication
jobs were running before the upgrade started, the jobs will continue to run without problems
after the upgrade completes.
The upgrade to StoreAll software 5.6 is supported only as an offline upgrade. Because it requires
an upgrade of the kernel, the local disk must be reformatted. Clients will experience a short
interruption to administrative and file system access while the system is upgraded.
There are two upgrade procedures available depending on the current installation. If you have a
StoreAll software 5.5 system that was installed through the QR procedure, you can use the automatic
upgrade procedure. If you used an upgrade procedure to install your StoreAll software 5.5 system,
you must use the manual procedure. To determine if your system was installed using the QR
procedure, run the df command. If you see separate file systems mounted on /, /local, /stage,
and /alt, your system was quick-restored and you can use the automated upgrade procedure.
If you do not see these mount points, proceed with the manual upgrade process.
• Automatic upgrades. This process uses separate partitioned space on the local disk to save
node-specific configuration information. After each node is upgraded, its configuration is
automatically reapplied.
• Manual upgrades. Before each server upgrade, this process requires that you back up the
node-specific configuration information from the server onto an external device. After the
server is upgraded, you will need to copy and restore the node-specific configuration
information manually.
