SBD Partitions

When you mark a device as Shareable for Clustering, the share information is added to the disk and consumes about 4 MB. This space is used in addition to the space needed for the SBD. For example, if you create a 1 GB (1024 MB) device for the SBD, 4 MB are used for the share information, leaving 1020 MB as available free space for the SBD partition.

In Step 4, added the -s option to the command and example.

Step 5 is required only if Cluster Services was initially installed without an SBD partition or mirrored SBD partitions. However, it does no harm to verify that the NCS: Shared Disk Flag attribute is enabled.
