At this point you should still be able to use the logical volume, but there will be no mirror redundancy.

To rebuild the mirrored volume, you replace the broken drive and recreate the physical volume. If you

use the same disk rather than replacing it with a new one, you will see "inconsistent" warnings when

you run the pvcreate command. You can prevent that warning from appearing by executing the

vgreduce --removemissing command.

[root@link-08 ~]# pvcreate /dev/sdi[12]

Physical volume "/dev/sdi1" successfully created

Physical volume "/dev/sdi2" successfully created

Next you extend the original volume group with the new physical volume.
