The problem is you have only about 4 GB space on your volume and you are trying to clone a 95 GB lun on the same volume. Try to increase the volume space using "vol size" so that there is atleast as much space in the volume as the lun you are cloning. Then try issuing the clone command.

The command you are using makes a Thick LUN and for making a thick LUN it will try to have the space equal to the size of LUN ( Incase you try to split it, it assumes that ways).

You have 2 options :

1) increase the size of Volume - Incase you want to have a thick LUN.

2) Create a thin LUN ( space reservation - off)

option 2 is possible via the below command :

filer> lun clone create /vol/test_vol/test_lun0_clone -o noreserve -b /vol/test_vol/test_vol_qtr/test_lun0 test_vol_snap1

Cheers !

Well if it's pretty simple, you are trying to delete the Snapshot which is backing you LUN clone.

It won't allow you to do it.

If you can tell us what you are trying to achieve maybe I'll able to give alternatives.

From where I see things, you created a clone from a Snapshot and not trying to delete the Snapshot. This doesn't make much sense to me.
