CheckMK appliance, Slave diskless

CMK version:
2.3.0p31
OS version:
Appliance 1.7.2
Error message:
i have upgraded my appliance to the latest version (from 1.6.7 → 1.6.8 → 1.6.9 → 1.7.0 → 1.7.2)
After that latest upgrade, i have my slave with the state; diskless and the synchronisation is inactive.

what to do to fix this ?

Hi,

i had the same issue. It comes with 1.7.3 and the ordering of the disks.
Check your disks of your appliances with lsblk - now the biggest partition is on sdb2.
Have now a look into your DRBD Config in etc/drbd.d/omd.res
On my standby node the device /dev/drbd0 was configure on disk /dev/sda2 which is not exisiting anymore. Just changed it to /dev/sdb2 and restartet the corosync service
