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 ?
Thank you ,
Adrian.
