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

Wow! Those are some old versions!

Just “drbdadm disconnect all” on the Primary node before the maintenance and “drbdadm connect all” afterwards. All else is magic!

Subject: [DRBD-user] Fwd: how to place secondary node in maintenance mode

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)
