It looks like you have a permission problem. The sanlock daemon needs to be able to use /dev/mapper/global-lvmlockd, but in your case it is getting an EACCES error when it tries to use that device. Check what UID/GID the sanlock daemon is running as, and that this GID is allowed to access disks. The sanlock daemon by default will try to run with UID/GID of sanlock/sanlock. I have things set up like this to allow that (the sanlock rpm will typically set this up for you): $ cat /etc/passwd | grep sanlock sanlock:x:179:179:sanlock:/var/run/sanlock:/sbin/nologin $ cat /etc/group | grep sanlock disk:x:6:sanlock tape:x:33:sanlock sanlock:x:179: You could also configure sanlock to run as root and not bother with the user/group setup. Set "uname = root" and "gname = root" in /etc/sanlock/sanlock.conf.
