3.5.1 Matrix Server Administration Guide

Appendix B: Error and Log File Messages 334

Majority of membership partitions are unwritable, possibly

due to a SAN or storage hardware failure. As a result, disk

imports and deports cannot be done, and some servers may be

unable to mount filesystems. In addition, Matrix Server’s

ability to recover from a future server failure is

compromised. Such a failure would leave Matrix Server no

option but to pause some or all filesystems throughout the

matrix to preserve filesystem integrity.

The servers in the matrix cannot write to the majority of the membership

partitions. Ensure that the servers can access the membership partitions

and have write access to them. If the disks containing the membership

partitions have failed, you will need to recreate the partitions. (See

“Manage Membership Partitions with mxmpconf” on page 287 for more

information.)

Matrix unable to take control of SAN, because a majority of

the membership partitions cannot be written or are corrupt,

possibly due to a SAN hardware failure or misconfiguration

and/or because servers have been excluded from the SAN. As a

result, some or all filesystem operations may be paused

throughout the matrix. In addition, filesystem mounts and

unmounts and disk imports and deports cannot be performed.

Ensure that all servers can access the membership partitions and have

write access to them. If a membership partition is corrupt, another alert

will specify its location. See “Manage Membership Partitions with

mxmpconf” on page 287 for corrective actions.

Matrix unable to take control of SAN, because another matrix

that includes NN.NN.NN.NN currently controls the SAN.

Possibly a networking failure or misconfiguration has

partitioned these servers from the servers that control the

SAN, or possibly this matrix has been misconfigured to

share membership partitions with another matrix.

Check the matrix configuration and add the server if it is not currently a

member. If your site has more than one matrix, use mxmpconf to make

sure that this server is using the correct set of membership partitions.
