I doubt it. Restore your backup. (And meditate on
the wisdom of those that have recomended it...).
The IO error is worrying though, it should _not_ happen.
Have a look into the system error log to see if this is
some lower-level error. It may also be some problem
with your LVM setup. (I cannot help there, in my opinion
LVM is too complicated and causes more trouble than it
has benefits.)
