I had a disk failure for my lvm mirror. It was between two disks. This was a failure of the primary.
I have been trying to recover the mirror but I cannot find directions as to what to do.
Seems like if I create a new partition, give it the old uuid and then try to load everything I get superblock errors.
So how do you fix up from a crashed primary mirror?
By the way, what is below is before I make a partition and create it properly with the uuid (as all the web pages say to do).
I have done that but get the file system superblock error when I mount it.
I have not done anything to the other partition but this is what I am starting with.
