Snapshot operation failed: No space left on device.

BUT


de-ham-san1> snap create vol1 test
de-ham-san1>

Re: Snapshot - No space left on device -

My first guess is that vol2 contains LUNs with reserved space and that there is not enough space in the volume to create a new snapshot and still keep the reserved space.

there are no differences... or?

Re: Snapshot - No space left on device -

I suggest opening a case with Netapp on this.
