29.13 Software RAID 1 Fails to Recognize a Replacement Device

If a drive fails that is part of a software RAID 1 device, your system might not recognize the replacement drive and does not begin remirroring automatically.

To recover:

  1. Reboot the system to re-scan devices and recognize the replacement drive.

  2. Unmount the NSS volumes on the software RAID device to stop the I/O.

  3. Expand the software RAID 1 device and specify space from the replacement drive as a new RAID segment. Remirroring begins automatically.

  4. Allow the remirror to complete before mounting the NSS volumes.
