How to monitor Aggregate Space when a SyncMirror is not updating
Applies to
- MetroCluster
- SyncMirror
Issue
A mirrored aggregate can run out of space if the SyncMirror is in a degraded state and the aggregate is near capacity.
Example of a degraded mirrored aggregate:
Aggregate aggr1_ClusterA_01 (online, raid_dp, mirror degraded) (block checksums)
Plex /aggr1_ClusterA_01/plex0 (online, normal, active, pool0)
RAID group /aggr1_ClusterA_01/plex0/rg0 (normal, block checksums)
