Error / Incident
There seems to be 0 or more than 1 DRBD primaries, that might mean many things:
- If there's 0 primaries -> the cluster is not working, and one of the nodes might have to be forced to become primary
- If there's >1 primaries -> there's a split brain, one of the nodes should be stopped and rejoined as secondary
You can go to both of the nodes and see the current drbd status by running:
root@labstore1005:~# cat /proc/drbd version: 8.4.7 (api:1/proto:86-101) srcversion: F7D2F0C9036CD0E796D5958 1: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate B r----- ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0 3: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate B r----- ns:0 nr:385762660 dw:385762660 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0 4: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate B r----- ns:0 nr:1229421488 dw:1229421488 dr:1471404 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0
This is how it should look if it runs ok, you can see that there's 3 drbd resources, all connected, for with this node is Secondary and the remote node is Primary, and both of them are UpToDate.
