Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

We have a pretty standard setup


both nodes are in sync without much issue now but during this week our DC
will perform some maintenance tasks that might incur in some connectivity
issues between both nodes.

How can put the slave node in maintenance (or any other mode) in order to
avoid any split brain situation?

I've been reading [1] and [2] but I can't find a clear answer to this.

should I just take down the service on the SLAVE node performing a *service
drbd stop* or instead disable the resource using *drbdadm down resourcename*

MASTER -> version: 8.0.16 (api:86/proto:86)
SLAVE -> version: 8.3.15 (api:88/proto:86-97)
