NSS Mirroring does not syncronize on OES Linux with multipath.

Environment

Novell Open Enterprise Server (Linux based) SP2

Situation


This only happens using multipath.
Use NSSMU to create a new cluster enabled NSS Pool and Volume.
Then mirror in using F3 from the partitions menu.
After the mirror is created you will see that it does not sync, 0% remirrored,
and Remirror Enabled is set to NO.

Resolution


If you create the Mirror this way it is necessary to manually
deactivate and reactivate the pool using F7 in the Pools menu of NSSMU.
Then it will synchronize.

This method of creating a mirror isn't used very often, usually only if an existing pool is later mirrored.
Creating it the normal way through the Raid Devices menu and the RAID-1
device was immediately in-sync at the time of creation.
