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)

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

must delete the software RAID
partition.

partition as described in
then re-create a non-mirrored SBD partition, as described in
