Force a system task

[mchartier]

Little question here :

When we do some maintenance and space reclaim on some lun, the Used column is decreasing as long as the reclaim operation is running on the OS/Hypervisor side. But the Rsvd column decrease when the array run it's defrag task.

Is there a way to force that, in case of someone messed up with a lun and we need to recover some space quickly? Because until the Rsvd is not dropped, running a compact cpg will not release all the space? right?

No you can't influence the reclaim process directly and a compact CPG won't return space until 128MB contiguous regions are available.
One option is to convert a TPVV to a FPVV and then back to TPVV which will force a defrag. However you need additional space to do this.
The other option is to have some temporary sacrificial FPVV volumes which can be deleted in an emergency to free space.

Ok thanks for the reply!
