Issue

One or more aggregate are showing mirror degraded and plex offline, preventing node giveback

Cause

Any failed disk in a RAID0 plex will cause the plex to enter a degraded/offline state

Solution

  1. View details of the aggregate to identify any failed plexes:

::> storage aggregate show -r -aggregate aggr_name

WARNING

Do not to delete plex without verifying a suitable spare exists
  1. Delete the failed plex:

::> storage aggregate plex delete -aggregate aggr_name -plex failed_plex

  1. Re-establish the mirror:

::> storage aggregate mirror -aggregate aggr_name

  1. Monitor the resynchronization and mirroring status of the plex until all mirrors are reestablished and all aggregates show mirrored, normal status:

::> storage aggregate show -r -aggregate aggr_name

  1. Proceed with giveback once mirror is complete

Additional Information

Error: Aggregate mirroring would fail for aggregate "aggr1"

Internal Notes

WARNING

Validate with an EE before unfailing the disk
