After a bunch of updates and a restart it started working for me again. Now the issue is really with thin LVs for which I opened a bugzilla last week: https://bugzilla.redhat.com/show_bug.cgi?id=1009546 There you would see all the details (file sizes, package versions etc). I can recreate the problem 100% of the time. Please let me know if you still need any more information. Thanks, Jorge _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
