My appologies if this has been addressed before.
I have an NFS volume on my FAS2240 that does not reclaim disk space when I move a VM off via Storage vMotion. All other volumes do.
Move 40GB VM from Saphire_Datastore to Gold_Datastore.
Volume free space prior to move:
Saphire - 108GB Gold - 328GB
Volume free space after move:
Saphire - 108GB Gold 290GB
I am relatively new to both VMware and NetApp storage, so I am unsure what direction to take. I have looked online, but most of the leads I have located relate to deleting VMs or reclaiming snapshot space.
Update: I just noticed in OnCommand System Manager that there are a group of tabs at the bottom of the Volume pane. The Saphire volume has 423GB of Snapshot data even though I have left the snapshot space at the default 5%. I guess it is safe to delete the larger snapshots, but I wonder why they would be so big in the first place. One snapshot is 256GB at was taken at 4:00 p.m. yesterday. It just happens that I was migrating a 250GB VM from Saphire to another datastore at about that time. Has anyone seen this type of behavior?
you don't want snapshots just go to the volume resize and
Snapshot reserve (%):00,
Then it will show, total allocated space as volume space.
Snapshot is working on copy on first write technology,so what ever may be updates happen it will take as snap that's why when you migrate the 250GB VM its taken entire snap.
Was this ever answered?
We have about 50GB of files that were deleted from a VOLUME over a month ago. THe problem is that none of the space seems to have been reclaimed. This is a netapp 250 running ontap 7.2.xx. It is used as an nfs server for a couple of Solaris boxes in out network
yes they do use snapshots. Weird thing is when on the solaris hosts I do a du-h command on the .snapshop dir and it seems like it's as big (168GB) as the volume itself
