Hi, i've a problem with drbd9 and auto-promote.
I mount a device on Node #1 , everything is fine. But if I try to mount the same device on Node # I got the following error. mount: /dev/drbd1000 is write-protected, mounting read-only mount: mount /dev/drbd1000 on /mnt failed: Wrong medium type In /var/log/messages I can see the following message Sep 27 08:27:21 drbd02 kernel: drbd testvolume: Auto-promote failed: Multiple primaries not allowed by config I'm using a three node drbd 9 cluster with linstor for management. The strange thing about it is that the existing volumes are still working with auto-promote, just new volumes have the problem. I build a new cluster for testing, with the same result. I guess that the upgrade to CentOS 7.7 could have something to do with that behaviour, I'll check that in the next days. I'm thankful for every hint ! Best regards, Michael
