Hello folks,

I establish a snapmirror relation ship between a source volume of size 3.0TB to destination volume 3.5TB.

when I initialize the snapmirror process it says snapmirror aborted.

Then i started creating snapshot manually but it says no free disk space on source volume I already started increasing the size of the source volume but still it tell's me no free disknspace.

please solve my issue as i have 3 lun's are carved on source volume and it is in production.

Thanks in advance.

Hi Naveen,

If you have a LUN inside your volume and use snapshots it would be prudent to set volume autosize on. Look up the command

and see what it does. Fractional reserve is a mechanism that allows to take space upfront for the LUN so that it never runs out of space.

this has been turned off now as you know, so now you need to allow the volume to grow in case it needs to. Do you use snapshots in the volume?
