Hi Peter,

I suspect that you have updated the Linux kernel and you now need to install a newer DRBD kernel module that is compatible with the new kernel.

If you use the rdqmstatus command without any parameters it will return output, such as:

Node:                                   myhost.mydomain
OS kernel version:                      5.14.0-362.8.1
DRBD OS kernel version:                 5.14.0-362.8.1
DRBD version:                           9.1.16
DRBD kernel module status:              Loaded

On your system the OS kernel version and the DRBD OS kernel version probably do not match, and the DRBD kernel module status is reported as something other than "Loaded".

See Problems after upgrading RDQM at https://www.ibm.com/docs/en/ibm-mq/9.3?topic=problems-after-upgrading-rdqm

For information about how to obtain a compatible DRBD kernel module, see IBM MQ Replicated Data Queue Manager Kernel Modules at https://www.ibm.com/support/pages/ibm-mq-replicated-data-queue-manager-kernel-modules

Hi Peter,

OK, this suggests that either Pacemaker or the RDQM service is not running.

You can check the status of Pacemaker by using systemctl status pacemaker.

If you open a support case then we can investigate the problem and help you to resolve it.

Kind regards,

Jamie
