Happy to report everything went well. This is what I did,
1. Boot and make sure the faulty disk is not mounted.
2. run the following,
# ddrescue -b 500M -n /dev/sd[faulty] /dev/sd[new] rescue.log
# ddrescue -dr3 /dev/sd[faulty] /dev/sd[new] rescue.log # 2-3 times
And now I have an exact copy of my LVM and everything is back up and
running as usual. :)
Thanks for all the help everyone.
