You are working on a fabric MetroCluster. After a site failure, the plex starts to resync automatically to the aggregate mirror of Aggr1. The plex now shows a status of resyncing. During this process, you experience a slow resync of the SyncMirror plex.
In this scenario, how do you solve the problem?
A. Add more disks to the aggregate to add more I/O capacity.
B. Destroy and re-create plex, then run a baseline sync.
C. Tune the resync speed by adding a QoS policy and limit the concurrent I/O to the aggregate.
D. Tune the resync speed using the storage raid-options command.
