Chapter 2: HP Clustered File System Commands 17

RESILVER. The membership partition is valid but its MP list does not match

the server’s local MP list. You will need to determine which membership

partitions are correct (the partitions specified in the local MP list, or the

partition labeled

RESILVER) and resilver accordingly.

CID_MISMATCH. The Cluster-ID is out-of-sync among the membership

partitions and must be reset. See “Reset the Cluster ID” on page

20.

Active and Inactive Membership Partitions

A membership partition can be either active or inactive. (This attribute is

reported in the last field of the record displayed by the mprepair

--get_current_mps command.) The current membership partitions should all

be active. If there are old membership partitions in the cluster, you may want

to either remove them or mark them as inactive.

A cluster could have an old membership partition if the disk containing it

becomes inaccessible and you then add another partition in its place.

When the disk access problem is corrected, the old membership partition will

still be on the disk and will be marked active.

When a membership partition is active, the disk containing the partition

cannot be imported into the cluster. You may see this situation if you want to

import a disk that was previously used by another cluster. To fix this

problem, use the --inactivate_mp option (described under “

mprepair

Options” below) to change the state of the membership partition to

“inactive.” You can then import the disk into the cluster.

Sizes for Membership Partitions

HP Clustered File System stores the size of the smallest membership partition

that was created during the HP Clustered File System installation. When you

add or replace a membership partition, the new partition must be at least as

large as that original partition. For example, if you originally created 2-GB,

3-GB, and 4-GB membership partitions, any membership partitions created

later on must be at least 2 GB in size.

Export Configuration Changes

When you change the membership partition configuration with mprepair, it

updates the membership list on the local server. It also updates the lists on the

disks containing the membership partitions specified in the local MP file.
