NWRAID1 remirror messages show up in /var/log/messages.

The following messages can appear in /var/log/messages:

These are harmless messages and can be safely ignored, below follows an explanation of these messages:

The server is telling the XXXX.sbd mirror to become "enabled" on this server. This message can be seen when a mirrored NSS pool is migrated from another cluster server. 

When this request is received by the RAID (nwraid.ko) driver, it always starts a re-mirror process, just in case the mirrors were not in sync at the time of the switch. If they are in sync, it immediately finished successfully. The re-mirror process is an active process that brings a non-synchronized mirror into sync. When it is in sync, the process ends, and regular I/O will maintain the mirror.

kernel: [495218.771163] NWRAID1: Stop Remirror (start) count=0 state=4 wait=0 

The re-mirror process is done, and it is trying to finish up the process and clean up the re-mirror engines.

The re-mirror process has successfully finished, and the server is completely done with the re-sync process.

These messages are expected, and indicate a successful process. Everything is good, and the mirrors are now fully in sync on this node.

kernel: [495218.771169] NWRAID1: Remirror enabled

The mirror has successfully been "enabled" on this node.

kernel: device-mapper: ioctl: Target type does not support messages
