Make sure LVM volumes are mounted inside vnodeState if the vnodes appear to exist but their LVM volumes are not mounted.  Also make sure to activate volumes cause they seem to go inactive across reboots.

Also bump the imq device limit down to 64 for now.  I still prefer to
fixup the problems with the 2.6.27 ovz kernel and change the imq setup

see.
