+ <note>
+ <para>This is optional for the MDT side only. The CATALOGS record the
+ llog file handlers that are used for recovering cross-server updates. Before
+ OI scrub rebuilds the OI mappings for the llog files, the related recovery
+ will get a failure if it runs faster than the background OI scrub. This will
+ result in a failure of the whole mount process. OI scrub is an online tool,
+ therefore, a mount failure means that the OI scrub will be stopped.
+ Removing the old CATALOGS will avoid this potential trouble. The
+ side-effect of removing old CATALOGS is that the recovery for related
+ cross-server updates will be aborted. However, this can be handled by LFSCK
+ after the system mount is up.</para>
