I guess you old configuration (other then then the new multipath.conf) is better then the defaults for now. > >>> 2.

The best way is to use git, checkout the patch, and build new rpms. git fetch https://gerrit.ovirt.org/vdsm refs/changes/50/70450/1 && git checkout FETCH_HEAD Please keep the old file and check that the diff between the old and new file match what we see in gerrit. diff -u /usr/share/vdsm/storage/monitor.py.old /usr/share/vdsm/storage/monitor.py https://gerrit.ovirt.org/#/c/70450/1/vdsm/storage/monitor.py Nir _______________________________________________ Users mailing list [email protected] http://lists.ovirt.org/mailman/listinfo/users
