Hello Patrick, thanks for your comment.
I can't see any messages regarding dlm in the syslog. When I call
`strace clvmd -d`, the first two lines are as followed:
[root@compute-0-1 ~]# strace clvmd -d
execve("/usr/sbin/clvmd", ["clvmd", "-d"], [/* 34 vars */]) = 0
uname({sys="Linux", node="compute-0-1.local", ...}) = 0
[...]
So, obviously, clvmd doesn't use the hostnames from cluster.conf (where
it should be c0-1.external.dns.com), but the ones provided by uname.
Does anybody know how to change this behaviour? Any help is greatly
appreciated!
Regards,
Sebastian
