Dear list,
We have an active-active cluster with vfilers. One vfiler in node-1 is having performance issues. Since node-1's CPU usage is much higher than node-2. I would like to migrate the vfiler from node-1 to node-2.
I found a feature called snapmover in vfiler manual. I found that the command "vfiler migrate -m nocopy" migrates a vfiler from node-1 to node-2 without actually copying data. This command merely changes the software disk ownership of disks that make up the vfiler and is non-disruptive. Furthermore, snapmover is now a non-license feature. Sounds too good to be true?
I want to know if there is any gotcha using snapmover. Does anybody have experiences using "vfiler migrate -m nocopy" command?
Our cluster is NetApp V3170.
Regards,
Ken Kawakubo
