I try to use "service qdiskd start", but it failed:
[root@as-2 ~]# service qdiskd start
Starting the Quorum Disk Daemon: [FAILED]
[root@as-2 ~]# tail /var/log/messages
...
Feb 26 09:19:40 as-2 qdiskd[14707]: <crit> Unable to match label
'testing' to any device
Feb 26 09:19:46 as-2 clurgmgrd[4032]: <notice> Reconfiguring
Here is my qdisk configuration, I copy it from "man qdisk":
<quorumd interval="1" tko="10" votes="1" label="testing">
<heuristic program="ping 10.56.150.1 -c1 -t1" score="1"
interval="2" tko="3"/>
</quorumd>
How to map label to device. Note: I did not have any shared storage.
