Kernel Warning Messages

vxvm:vxio:WARNING: Failed to log the detach of the DRL volume volume

◆ Description: An attempt failed to write a kernel log entry indicating the loss of a DRL

volume. The attempted write to the log failed either because the kernel log is full, or

because of a write error to the drive. The volume becomes detached.

◆ Action: Messages about log failures are usually fatal, unless the problem is transient.

However, the kernel log is sufﬁciently redundant that such errors are unlikely to

occur.

If the problem is not transient (that is, the drive cannot be ﬁxed and brought back

online without data loss), recreate the disk group from scratch and restore all of its

volumes from backups. Even if the problem is transient, reboot the system after

correcting the problem.

If error messages are seen from the disk driver, it is likely that the last copy of the log

failed due to a disk error. Replace the failed drive in the disk group. The log

re-initializes on the new drive. Finally force the failed volume into an active state and

recover the data.

vxvm:vxio:WARNING: Failure in RAID-5 logging operation

vxvm:vxio:WARNING: log object object_name detached from RAID-5 volume

◆ Description: Together, these errors indicate that a RAID-5 log has failed.

◆ Action: To restore RAID-5 logging to a RAID-5 volume, create a new log plex and

attach it to the volume.

vxvm:vxio:WARNING: Illegal vminor encountered

◆ Description: An attemptwas madeto open avolume devicebeforevxconfigd loaded

the volume conﬁguration.

◆ Action: None; under normal startup conditions, this message should not occur. If

necessary, start VxVM and re-attempt the operation.

vxvm:vxio:WARNING: Kernel log full: volume detached

◆ Description: A plex detach failed because the kernel log was full. As a result, the

mirrored volume will become detached.

◆ Action: It is unlikely that this condition ever occurs. The only corrective action is to

reboot the system.

vxvm:vxio:WARNING: Kernel log update failed: volume detached

◆ Description: Detaching a plex failed because the kernel log could not be ﬂushed to

disk. As a result, the mirrored volume became detached. This may be caused by all

the disks containing a kernel log going bad.

◆ Action: Repair or replace the failed disks so that kernel logging can once again

function.
