Deactivate all Ceph OSDs on a node.
So, I needed to do some infra maintenance. and quickly discovered that the process of safely offlining the OSDs on a node was taking forever.
The steps we need to take are fairly simple.
ceph osd set nooutWhich gets us the response:
noout is set
Lets get to it, Shall we?
shutdown -h now
press power button
Do Maintenance here
Start node back up
Validate ceph is healthy
