First off, you should take complete disk-level backups of your remaining disks
in the VG.

If the messages are accurate, there's likely to be only a problem with lv02, 
not lv03 which you're trying to mount, so try a normal (rw) mount of
lv03 and see if the ext3 recovery copes, or else try fsck.  If you took
the disk-level backups first you can restore the disks from the backups
if fsck makes things worse and you need to try other restoration
methods.

*AFTER* you've completed extracting your data, you can use LVM2's vgreduce
to tidy up the LVM configuration, removing the lost PVs and
partially-missing LV completely. But read the vgreduce man page first
and use --test before running it for real to check it's going to do
something sensible in your circumstances.
