Snapshots don’t
dedup, wait a bit and see what it looks like once all the older snapshots have
timed out. Deleting them manually should work but it can take quite a while to
claim the freed space back if you’re filer is fullish.

Subject: CIFS volume deduplication
Hi everyone,
We
have a NetApp Filer 3040 running 7.2.6.1. We have configured Dedupe on a
few volumes with ESX VM’s and have saved about 15-25% disk space.
Last week, we ran it on our CIFS Volume (Homedir, Shared Drives, etc), which is
950Gigs, but we only saved about 700 megs.
These are the following commands we used to start the deduplication...
sis on VOL
sis start -s VOL
It took about 8 hours to scan the volume. Afterwards, "df -s"
showed that it saved 0%.
Netapp suggested that I wait for the old snapshots to delete, but it still
didn't help.
Does anyone have any ideas about this ?
Thanks
Matt
