I just tried to set up sanlock on F17 using the instructions at
http://libvirt.org/locking.html, but libvirtd refuses to start with
the sanlock error in the logs:
Jun 29 19:56:20 nienna sanlock[8423]: 19846 open error -13
/var/lib/libvirt/sanlock/__LIBVIRT__DISKS__
I confirmed that user sanlock can create, read and write files in
/var/lib/libvirt/sanlock
The only thing I can think of that's slightly odd about my setup is
that I'm only concerned with the local machine, so that directory is
not an NFS mount. Anybody have any thoughts on what's going wrong
here?
TIA,
Dave

Also disabling selinux does not help.

Hello Dave,
AFAIK, there are wdmd and sanlock bugs now:
https://bugzilla.redhat.com/show_bug.cgi?id=832056
https://bugzilla.redhat.com/show_bug.cgi?id=832935
https://bugzilla.redhat.com/show_bug.cgi?id=831908 (selinux enable)
https://bugzilla.redhat.com/show_bug.cgi?id=820173
In addition, for sanlock version >= 2.1-1, if you append SANLOCKOPTS="-w 0"
into /etc/sysconfig/sanlock then restart sanlock service, sanlock will stop due to a
segfault error, please see the following bug:
https://bugzilla.redhat.com/show_bug.cgi?id=831906
In fact, we need to updates docs due to sanlock configuration change, and should
append/uncomment
SANLOCKOPTS="-U sanlock -G sanlock -w 0" line in /etc/sysconfig/sanlock instead
of old SANLOCKOPTS="-w 0".
But, I haven't try sanlock on F17, maybe, it's different from RHEL6, and hope
these are helpful for you ;)
Good Luck!
Alex

Well, -13 is the EACCESS errno, so there must be some kind of permissions
problem in there, be it DAC or SELinux.
You might try strace'ing sanlockd just to be sure, and check that it
really is running under the user/group that you think it is.
