With snapmirror final cutover will likely take not much longer than volume remounting.

Thanks, Andrey – I’m happy that it’s not just me being unable to do that but on the other side I find it strange that a simple operation like that is not possible in cDOT…

I will try my luck with snapmirror and see if that would help me get it going – for NDMP and snapmirror I will definitely have to note the LUN serials in before and restore them manually afterwards before bringing the LUNs offline; the problem with snapmirror or ndmp is just that it’s a copy process after all so it takes some time to complete (leaving alone the fact that I would also need the space for that) and I wanted to just quickly change the presenting vFiler for our customer in a short maintenance window – seems that the maintenance window will be a bit longer now :-/

Best,

No. And if someone knows tricks how to do it - please share!

The only way is to use snapmirror (or ndmpcopy … although I’m not sure whether external ndmcopy handles LUN correctly, and there is no internal one …)

Hey there,

is it possible to move a volume from one vserver to another one on the same node and by using the same aggregate?

I can find plenty of possibilities to move a volume to a different physical node or aggregate, but not for what I want to do.

node01 -> aggr01 -> vFiler01 -> Volume01 -> LUN01

node01 -> aggr01 -> vFiler02 -> Volume01 -> LUN01

so basically, I want to „dismount“ Volume01 from „vFiler01“ and mount it on „vFiler02“ – is that possible at all?
