2.3 Error Messages

This section presents error messages that can occur with CVM. Each message is accompanied by an explanation and a suggested user action.

Some of these messages can appear on the console; others are returned by vxclust.

error in cluster processing

This can be due to an operation inconsistent with the current state of the cluster (such as an attempt to import or deport a shared disk group from the slave). It can also be caused by an unexpected sequence of commands from vxclust.

Make sure that the operation can be performed in the current environment.

cannot find disk on slave node

A slave node cannot find a shared disk. This is accompanied by the syslog message:

vxvm:vxconfigd cannot find disk disk

Make sure that the same set of shared disks is online on both nodes.

Examine the disks on both the master and the slave with the command vxdisk list and make sure that the same set of disks with the shared flag is visible on both nodes. If not, check connections to the disks.

disk in use by another cluster

An attempt was made to import a disk group whose disks are stamped with the ID of another cluster.

If the disk group is not imported by another cluster, retry the import using the -C (clear import) flag.

vxclust not there

An error during an attempt to join the cluster caused vxclust to fail. This can be caused by the failure of another node during a join or by the failure of vxclust.

Retry the join. An error message on the other node can clarify the problem.

unable to add portal for cluster

vxconfigd was not able to create a portal for communication with the vxconfigd on the other node. This can happen in a degraded system that is experiencing shortages of system resources (such as memory or file descriptors).

If the system does not appear to be degraded, stop and restart vxconfigd and try again.

vol recovery in progress

A node that crashed attempted to rejoin the cluster before its DRL map was merged into the recovery map.

Retry the join again later (when the merge operation has completed).

cannot assign minor #

The slave attempted to join, but an existing volume on the slave has the same minor number as a shared volume on the master.

This message should be accompanied by the following console message:

WARNING vxvm:vxconfigd minor number ### disk group group in use

Before retrying the join, use vxdg reminor diskgroup ### (see the vxdg(1M) manual page) to choose a new minor number range either for the disk group on the master or for the conflicting disk group on the slave. If there are open volumes in the disk group, the reminor operation will not take effect until the disk group is deported and updated either explicitly or through system restart.

master sent no data

During the slave join protocol, a message without data was received. This message is only likely to be seen in the case of a programming error.

Contact Customer Support for more information.

join in progress

An attempt was made to import or deport a shared disk group during a cluster reconfiguration.

Retry later.

join not allowed now

A slave attempted to join the cluster when the master was not ready. The slave will retry automatically. If the retry succeeds, the following message should appear:

vxclust: slave join complete

No action is necessary if the join eventually completes. Otherwise, investigate the cluster monitor on the master.

Disk reserved by other host

An attempt to put a disk online whose controller has been reserved by another host will fail with this error.

No action is necessary. The cluster manager will free the disk and the volume manager will put the disk online when the node joins the cluster.

vxvm:vxconfigd: group group exists

The slave tried to join the cluster, but there is already a shared disk group in the cluster with the same name as one of its private disk groups.

Use the vxdg newname operation to rename either the shared disk group on the master or the private disk group on the slave.

WARNING: vxvm:vxio: Plex plex detached from volume volume NOTICE: vol_kmsg_send_wait_callback: got error 22 NOTICE: commit: NOTE: Reason found for abort: code=6

These messages can appear during a plex detach operation on a slave.

These messages provide information and require no user action.

WARNING: vxvm:vxio: read error on Plex plex of shared volume volume offset 10 \ length 1 WARNING: vxvm:vxio: Plex plex detached from volume volume NOTICE: commit: NOTE: Reason found for abort: code=2 NOTICE: ktcvm_check: sent to slave node: node=1 mid=196

These messages can appear during a plex detach operation on the master.

These messages provide information and require no user action.
