Hello Everyone,

I have a query that how to get the exact used space of a volume (actual used space of a volume without deduplication), in the case of deduplication is enabled in a 7-mode.

Thanks in advance for the help..

Regards

Anil

Just use "df". This shows physically used space on the volume.

"sis status -l" is also useful to know more detail about deduplication.

Hi,

df -s <vol/volname>
df -s <volname> --- Shows space savings from deduplication as well as actual physical used capacity per volume.

sis status [-l] <vol/volname > --- Returns the current status of deduplication for the specified flexible volume. The –l option displays a long list.

Thanks
