This creates a RAID 1 device with the name /dev/evms/nodes/cluster. sbd. 5 Reboot all cluster nodes. 8. 16. 5 Deleting a Non-Mirrored Cluster SBD Partition You must delete an existing SBD partition for the cluster before you attempt to create (or re-create) an SBD partition. The existing SBD partition might have been created during the Novell Cluster Services installation, or later by using the sbdutil. 1 At a Linux terminal console of a cluster server, log in as the root user. 5 Click Delete to delete the partition and its contents, then click OK to confirm the deletion. 6 If you have more than one node in the cluster, use one of the following methods to create a new SBD partition: Section 8. 16. 3, "Creating a Non-Mirrored Cluster SBD Partition, " on page 111 Section 8. 16. 4, "Creating a Mirrored Cluster SBD Partition, " on page 112 7 Join the nodes to the cluster. Managing Clusters 113 novdocx (en) 7 January 2010 8. 16. 6 Deleting a Mirrored Cluster SBD Partition You must delete an existing SBD partition for the cluster before you attempt to create (or re-create) an SBD partition. Because it is mirrored, you delete the software RAID device instead of deleting the two partitions separately. The existing mirrored SBD partition might have been created during the Novell Cluster Services installation, or later by using the SBDUTIL or the EVMS GUI tool. 1 At a Linux terminal console of a cluster server, log in as the root user. 4 Select the software RAID 1 for the SBD partition you want to delete. 5 Click Delete to delete the software RAID and its member segments, then click OK to confirm the deletion. 6 If you have more than one node in the cluster, use one of the following methods to create a new SBD partition: Section 8. 16. 3, "Creating a Non-Mirrored Cluster SBD Partition, " on page 111 Section 8. 16. 4, "Creating a Mirrored Cluster SBD Partition, " on page 112 7 Join the nodes to the cluster. 8. 16. 7 Removing a Segment from a Mirrored Cluster SBD Partition You can remove a segment from a mirrored cluster SBD partition and keep the remaing SBD partition. The software RAID definition remains, so if you delete the remaing partition later, you must delete the software RAID instead of simply deleting the parition as with a standalone SBD partition. IMPORTANT: To get rid of the software RAID definition, you must delete the mirrored SBD partition as described in Section 8. 16. 6, "Deleting a Mirrored Cluster SBD Partition, " on page 114, then re-create a non-mirrored SBD partition, as described in Section 8. 16. 3, "Creating a NonMirrored Cluster SBD Partition, " on page 111. Beginning in OES 2 SP2, you can specify which segment to keep when you use NSSMU to remove a segment from a software RAID 1 (mirror) device. 1 At a Linux terminal console of a cluster server, log in as the root user. 4 Select the software RAID1 device for the cluster SBD partition that you want to manage. 6 Select the member segment you want to delete, then select Delete to remove the segment. 114 OES 2 SP2: Novell Cluster Services 1. 8. 7 for Linux Administration Guide novdocx (en) 7 January 2010 The RAID definition will still exist for the remaining segment of the mirrored SBD partition, but it reports that it is not mirrored. 7 Join the nodes to the cluster. 8. 17 Customizing Cluster Services Management Some portions of Novell Cluster Services management can be performed and customized by using virtual XML files that exist in the /admin/Novell/Cluster directory on Linux. The cluster-related virtual XML files (management access points) are created on each server's / admin/Novell/Cluster directory. This means that as long as the cluster is running, you can always access the cluster-related XML virtual files in the /admin/Novell/Cluster directory.
