Hi. Has anyone successfully reclaim space? It seems for me sometimes it works and sometimes it doesnt.
We are on vSphere v6.5 and SCOS 7.3x.
I know the automatic UNMAP will not work because of the supported block size the auto unmap needs and Compellent doesnt use.
But the cli esxcli storage vmfs unmap should work right?
So I had a 2TB volume which I emptied of a single VM awhile back. So VMware reported 2TB of 2TB free.
Compellent shows 160GB that was sitting on Tier3.
We have 2 replay profiles on each datastore. 15min with 1hr expiration. And 24hr with 48hr expiration.
So earlier today I tried to reclaim it instantly, and this should work.
ran the unmap command from a hypervisor
Took a manual snapshot of the datastore
Then expired all other snapshots
At this point the space should have been reclaimed right?
