I tried a few and none seemed to work, but I restored one from before I made
snapshots and recovered from this.
I now have my system back (/usr, /var)
As for /home, as soon as I tried to access it (e2fsck, tune2fs -O
^has_journal, or whatever), the process hung in "wait_o" according to ps.
I tried to restore the VG to its state before I added snapshots, but that
only made it go away :-(
