11.7 Deleting Shared Storage

Make sure to offline the cluster resource before attempting to delete either the cluster resource or the
shared storage resource.
WARNING: If you attempt to delete a cluster resource or the shared storage without first offlining
it, deletion errors occur, and the data associated with the shared storage is not recoverable.
11.8 Known Issues for Working with Cluster
Resources for Linux POSIX Volumes
Section 11.8.1, "Dismount Volumes before Onlining a Comatose Resource," on page 178
Section 11.8.2, "Cluster Services Must Be Running When Using EVMS," on page 178
Section 11.8.3, "Close EVMS Utilities When They Are Not In Use," on page 178
Section 11.8.4, "Do Not Migrate Resources When EVMS Tools Are Running," on page 179
11.8.1 Dismount Volumes before Onlining a Comatose
Resource
If a Linux POSIX volume resource goes comatose, you must verify that the volume is not mounted
on any node in the cluster before bringing the resource online again. Failure to do so might result in
corruption.
WARNING: To avoid corruption, make sure the Linux POSIX volume in a comatose resource is
dismounted from any node before attempting to online it.

11.8.2 Cluster Services Must Be Running When Using EVMS

Novell Cluster Services must be running on all nodes in the cluster whenever you make any
modifications to the cluster or cluster resources by using the EVMS management tools or the
Clusters plug-in in iManager.

11.8.3 Close EVMS Utilities When They Are Not In Use

The EVMS management utilities (evms, evmsn, evmsgui) lock the EVMS engine while running,
potentially blocking other EVMS-related actions from taking place. This affects NSS pool and
volume actions and Linux POSIX volume actions.
Do not run the EVMS management utilities when they are not being actively used. Do not
concurrently open multiple instances of the utilities. Do not open the utilities when using NSSMU or
the Clusters or Storage plug-ins for iManager.
