If the capacity becomes unbalanced among storage nodes due to storage node addition or removal, drive data relocation runs to optimize the capacity efficiency of each storage node by enabling capacity balancing among storage nodes.
Suspend drive data relocation in the following cases. For how to suspend drive data relocation, see Suspending drive data relocation (Bare metal). For how to resume drive data relocation from a suspended state, see Resuming drive data relocation (Bare metal).
-
To prevent performance degradation due to drive data relocation (resume drive data relocation at night when system load is light)
-
To perform other maintenance operations first (resume drive data relocation after other maintenance operations are finished)
