If you are using NFS at lesat so you shouldn't need to know the file names, there is the ability to tell the NFS server to release all locks associated with a dead host. > I do an sha256 hash from /var/lib/libvirt/images/lock/MyVM.img but I > don't get the same hash code form virtlockd ? It uses the sha256 has of the filename. How did you generate your hash ? If using shell make sure you don't include a newline ie you want echo -n /var/lib/libvirt/images/lock/MyVM.img | sha256sum not a plain 'echo' as that includes a newline Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :| _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
