It could be that the issue comes from the bug in fence_legacy,
which has been resolved in the meantime. Can you try to edit that
and replace the split command (line 86) with the following (i.e.
just append ", 2"):
($name,$val)=split /\s*=\s*/, $opt, 2;
The file location should be /usr/sbin/fence_legacy.
Can you please see if that helps?
Cheers,
Dejan
