I am testing HA two node + NAS iscasi LUN as quorum disk
Anyway when i am turning on nodes without quorum, my cluster cant start VMS due to cman not started.

How can i fix so that cman will start even if qdiskd is offline when nodes are starting ?
Ofcourse when two nodes are booting and NAS is online, everything goes smooth

root@node2:~# /etc/init.d/cman start
Starting cluster:
Checking if cluster has been disabled at boot... [ OK ]
Checking Network Manager... [ OK ]
Global setup... [ OK ]
Loading kernel modules... [ OK ]
Mounting configfs... [ OK ]
Starting cman... [ OK ]
Starting qdiskd...
[FAILED]

Hi,
you can use pvecm expected.
but you should be very careful with this.
This what you describe is the normal behave if you have no quorum.
 
no its not the case.
There are 2 servers so 2 votes avaible.
And one quorum disk = 1 vote

So when quorum is offline, why cant servers runt their services ?

cman cant start due to qdiskd process startup failure.
It should be possible to skip qdiskd and start cnam normally.
 
Anyone knows how to solve this ?
So how can i start node1 + node2 when qdisk is failing ?

Its is only problem in service startup because it cant start cluster when qdiskd service cant start.
There must be a way to get this working. After all i have all quorum needed but quorum is not the case.
Only "service failed" is the problem that prevent cluster from start other services.
 
little update: When i turn off HA for VM, i can start it normally.
So problem is only for HA. At least i can start VM in case of quorumd failed :)

But anyway this should work anyway iwthout quorum disk enabled (in case of failure)
