Sorry, its "ps -efZ", but we already know its not selinux.

Does sanlock run with the right groups?

On a working system:

$ ps -efZ | grep sanlock | grep -v grep
system_u:system_r:sanlock_t:s0-s0:c0.c1023 sanlock 983 1  0 11:23 ?
    00:00:03 /usr/sbin/sanlock daemon
system_u:system_r:sanlock_t:s0-s0:c0.c1023 root 986  983  0 11:23 ?
    00:00:00 /usr/sbin/sanlock daemon

The sanlock process running with "sanlock" user (pid=983) is the
interesting one.
The other one is a helper that never accesses storage.

$ grep Groups: /proc/983/status
Groups: 6 36 107 179

Vdsm verify this on startup using vdsm-tool is-configured. On a working system:

$ sudo vdsm-tool is-configured
lvm is configured for vdsm
libvirt is already configured for vdsm
sanlock is configured for vdsm
Managed volume database is already configured
Current revision of multipath.conf detected, preserving
abrt is already configured for vdsm

Looks correct.
