Nova NetApp backend LIF migrate NFS Lock reclaim
Hi Guys
We have an OpenStack Stein environment with Netapp configured as the storage backend for Nova, Glance and Cinder using NFS v4.1. We upgrade our Netapp appliances multiple times a year, when performing the upgrade we failover the IP to a different Netapp storage node. This results in every virtual machine losing R/W access to its boot disk, a reboot of the VMs is required to escape this state.
We would like the VMs to regain R/W access to their boot disks after the migration of the IP on Netapp storage node without a reboot. Can anyone advise?
Many Thanks
Did you ever find a solution for this? We are seeing a similar issue during ONTAP upgrades.
