Hi we have the following storage model and I have checked the threshold limit for the model FAS2050 for a deduplicated volume is 2TB.
I want to increase the space of the volume beyond the threshold limit.
FAS2050 : with ontap 7.3.3
message while adding more space to the volume
vol size: Selected SIS volume size is too large; maximum is 2048g
df -s output of the volume
Filesystem used saved %saved
/vol/vol1/ 2094239660 0 0%

0% savings seems a bit low for any kind of volume. Did you run SIS on the volume at all? "sis start -s /vol/<volumename>" ?
As soon as you get more free space by deduplication, you can increase the volume size again. The number of physically allocated blocks cannot exceed 2TB. So if you save, say, 50g by deduplication you can increase the size of the volume by 50g afterwards

I have the same issue, need to increase a dedupe volume over the limit.
/vol/vol1/ 1066374992 201679956 16%
Can I stop sis when the volume is 99% full, then increase the volume?
Can anyone update me on the procedure for this action?

You can stop SIS anytime on the volume.
Then increase the size and run the "sis undo" command to make it a "normal" volume again.
PS "sis undo" is an "advanced" command (priv set advanced)

vol size gives me this error:
vol size: Selected SIS volume size is too large; maximum is 1024g.
Even after I disabeled sis the error appears. So can I do a "sis undo" before sizing the volume? Or will that trash data?
