[ceph-users] Re: changing acces vlan for all the OSDs - potential downtime ?

Hi all, I have a Ceph cluster with a standard setup : - the public network : MONs and OSDs conected in the same agg switch with ports in the same access vlan - private network :  OSDs connected in another switch with a second eth connected in another access vlan I need to change the public vlan on the first switch and the private vlan and the second switch. Although it should be a trivial operation (just change the vlan range ports in a single command), it means that all the OSDs and MONs will not be able to communicate with each other for a few seconds . (first on the public network, then on the private network).  Do you know if this very short period of downtime will mess up the cluster somehow ? Is there a best practice on how to do this safely ?
