Thank you,Maybe my question was not clear enough.Let's say I have a cinder-volume with nfs as backend and I need to take down the nfs server for maintenance, can I put the cinder-volume-nfs into some sort of maintenance mode, work on the nfs server bring it back, then reactivate the cinder-volume-nfs?Regards.Le dim. 2 avr. 2023 à 13:54, Ignazio Cassano <ignaziocassano@gmail.com> a écrit :Or using the openstack command :Il Dom 2 Apr 2023, 14:46 wodel youchi <wodel.youchi@gmail.com> ha scritto:Hi,When you have multiple cinder backends, and you need to take down one of them for maintenance purposes, what is the best way to proceed?Does Openstack have the notion of : cinder backend in maintenance mode?Regards.
