Initial autosync operation takes a long time to complete for data volumes larger than 3TB (3966713)

If SmartMove is enabled and autosync is in progress, the SmartSync operation performs a difference-based synchronization, which is faster than full synchronization. However, for data volumes larger than 3TB, the SmartMove feature gets disabled if the allocated DCM plexes are not sufficiently sized. Therefore, the autosync operation performs full synchronization and synchronizes the entire volume.

Workaround

  1. To enable the smartmove feature for volumes larger than 3TB, use the following command:

    # vxassist -g <disk_group_name> addlog <volume_name> logtype=dcm loglen= <size>

  2. where, the size is a minimum of 1024 blocks.
