I ran a volume move which completed successfully in 4.5 hours, 137.7MB/s. During this time and several hours afterwards I have had users report problems with NFS mounts however the issues the users were reporting were not using the nodes or aggregates where the volume move was taking place. My question is, can a volume move effect performance elsewhere in the cluster?
Thanks @aladd for your reply. In the first example I looked at the LIF and volume being mounted were indeed on different nodes, different HA pairs in fact. So in summary, if running a volume move utilizes the cluster interconnect then all other traffic in the cluster also using the interconnect could potentially be effected. So from this do I conclude it is preferable in Linux when NFS mounting to use a LIF on the same node that the volume is located to avoid traffic using the interconnect?
This can be based purely on circumstances and your needs. We have a requirement for a 10G connection for cluster interconnect to facilitate this traffic, however depending on your environment and use of the system can have an impact.
