Crm cluster cannot mount drbd after switching


Here my freepbx active/passive cluster. it works on proxmox hypervisor.

After turn off master, res_filesystem_1 on the second node does not start. drbd does not mount. and services that uses drbd didnt start.

i have many errors then i show status /usr/sbin/crm_mon -1 -r -f

If i try to reset all resources

crm_resource --resource res_filesystem_1 -P 
crm_resource --resource res_mysql_mysql_fpbx -P 
crm_resource --resource res_asterisk_asterisk -P 
crm_resource --resource res_apache_apache -P 

all services start and works correctly before the next node switching.

After turned off, node cannot shutdown and say: waiting for cluster services to unload. I try to turn it off by button on vm, and it still not mount on the second node.

Then i swith nodes cat /proc/drbd show correctly Primory/secondary

Here is the crm conf

crm configure show

Solution

  • What I really seem to be missing here (according to the logs you provided) is an order and a matching colocation primitive. Both help your cluster starting services in the correct order AND on the same node. For example: res_drbd_1 first, then res_Filesystem_1.

    It could look like this:

    order o_drbd_1_before_Filesystem_1 +inf: ms_drbd_1:promote res_Filesystem_1:start
    colocation co_Filesystem_1_with_drbd_1 +inf: res_Filesystem_1 ms_drbd_1:Master
    

    (elaborate for all the other configured services)
