3.6.0 Matrix Server Upgrade Guide (5697-7085, February 2008)

Chapter 5: Post-Upgrade Steps 39

CAUTION: Be sure to back up the filesystem on the volume before

recreating the volume. This procedure requires that you also

recreate the filesystem on the volume, which destroys all data

on the filesystem. After the volume and the filesystem are

recreated, you can manually restore the data from your

backup.

To recreate a concatenated dynamic volume, take these steps:

1. Back up the data on the volume.

2. Recreate the dynamic volume. On the PolyServe Management

Console, select Storage > Dynamic Volume > Recreate and then choose

the volume that you want to recreate. You can change or reorder the

subdevices used for the volume if desired.

To recreate the volume from the command line, first run the

dynvolume destroy command and then run the dynvolume create

command.

mx dynvolume destroy <volumeName>

mx dynvolume create <subDeviceName,subDeviceName,...>

3. Create a new filesystem on the volume. On the PolyServe

Management Console, select Matrix > Add > Add Filesystem. Select

the recreated volume on the Create Filesystems window and set the

appropriate filesystem options.

To create the filesystem from the command line, use either the mx fs

create command or the psfsformat command. See the Matrix Server

Administration Guide for details about these commands.

4. Restore the filesystem data to the new dynamic volume.

Remove Custom Setting for GcTrimLevel

In previous releases of Matrix Server, there have been recommendations

to add a registry setting for GcTrimLevel to restrict the amount of

Windows pool memory consumed by the product. In Matrix Server 3.6, a

new tunable GcTrimMax has been added that caps the maximum number

of FCBs that the product will cache (the default is 10,000). With the new

settings, the defaults should be suitable for all but the most unusual
