<div dir="ltr"><br class="gmail-Apple-interchange-newline"> Hi,
<br>
<br>i've a problem with drbd9 and auto-promote.
<br>
<br>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.
<br>
<br>mount: /dev/drbd1000 is write-protected, mounting read-only
<br>mount: mount /dev/drbd1000 on /mnt failed: Wrong medium type
<br>
<br>In /var/log/messages I can see the following message
<br>
<br>Sep 27 08:27:21 drbd02 kernel: drbd testvolume: Auto-promote failed:
Multiple primaries not allowed by config
<br>
<br>I'm using a three node drbd 9 cluster with linstor for management.
<br>The strange thing about it is that the existing volumes are still
working with auto-promote, just new volumes have the problem.
<br>
<br>I build a new cluster for testing, with the same result.
<br>
<br>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.
<br>
<br>I'm thankful for every hint !
<br>
<br>Best regards,
<br>Michael
