That looks good.  I understand the I/O error now.  It is from an attempt to
read from the missing PV.  The one question I have is, "Did you ever resize
the root filesystem?"  I suspect not, since you would have seen errors from
the missing blocks.  If you _did_, then it should be "interesting" trying
to get the filesystem back into its available space.  In any case, fixing
the LVM structure has to come first, so I say go ahead without the "--test"
option.
