I have now managed to fix the problem. I ran vgcfgbackup, then made a copy of the backup for safety purposes. I than hand edited the original backup to remove the missing pv (pv4), the root lv and the pvmove0 lv. I then than vgcfgrestore. Everything is working.
There must be a better way of doing this. Hand editing cfg files is not safe or sensible. What have I missed?
