What happens to a shadow migration job if a pool is failed over in a cluster, or both system disks fail and a newhead node is required when using shadow migration feature?
A.
All data necessary to continue shadow migration without interruption is stored in the Write-Optimized
Cache.
B.
All data necessary to continue shadow migration without interruption is removed and the job starts from the
beginning.
C.
All data necessary to continue shadow migration without interruption is kept with the storage pool.
D.
All data necessary to continue shadow migration without interruption is stored in NVRAM.
Explanation:
Shadow migration implemented using on-disk data within the filesystem, so there is no external database and no data stored locally outside the storage pool. If a pool is failed over in a cluster, or both system disks fail and a new head node is required, all data necessary to continue shadow migration without interruption will be kept with the storage pool.
