3.1.2 Matrix Server Upgrade Guide

Chapter 4: Double Upgrade Procedures 50

Then install MxFS-Linux 3.1.2 from the product CD or the location

where you have downloaded the software.

# rpm -i <mountpoint>/mxfs-3.1.2-<xxxx>.x86_64.rpm

42. Copy your new license file to /etc/polyserve/licenses/license on the server.

43. If you did a fresh installation of the operating system, recreate mount

points for the PSFS filesystems.

44. Start Matrix Server on the upgraded server. Run the following

command:

# /etc/init.d/pmxs start

45. Re-enable the server (right-click on the server and select Enable).

46. Repeat steps 28 through 45 on each remaining server.

All servers are now running Matrix Server 3.1.2 in 64-bit mode.

If you want to enable filesystem quotas on your PSFS filesystems, first

unmount the filesystems one-at-a-time (or one export group at-a-time)

and then enable quotas. Use the following procedure to unmount the

filesystems. For more information about quotas, see “Enable or Disable

Quotas” in Chapter 8 of the PolyServe Matrix Server Administration Guide.

Unmount Filesystems on Clusters With MxFS-Linux

When unmounting filesystems, you should be aware of the following

problem, which is also documented in the release notes as defect 10742.

Before a PSFS filesystem can be unmounted, all processes must release

their references on the filesystem. The NFS server process retains these

references on exported filesystems, and prevents the filesystem from

being unmounted. To work around this problem, you will need to take

the following steps to unmount a PSFS filesystem that is being exported

from an Export Group. (This procedure does not impact other Export

Groups exporting different filesystems via the same server.)

1. Disable the Export Groups that are exporting the filesystem to be

unmounted. You will need to disable the Export Groups on each

server from which the filesystem is to be unmounted.
