Re: [libvirt] sanlock on F17



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

Also disabling selinux does not help.
