I have a Centos 7 system with an mdraid array (raid 1). I removed a
drive from it a couple of months ago and replaced it with a new drive.
Now I want to recover some information from that old drive.
I know how to mount the drive, and have done so on another system to
confirm that the information I want is there.
My question is this:
What is going to happen when I try to mount a drive that the system
thinks is part of an existing array?
To put it another way: I had two drives in md127. I removed one (call
it drive1), and replaced it with a new drive. Some files were
accidentally deleted from md127, so now I want to connect drive1 back to
the same machine and mount it as a separate array from md127 so I can
copy the files from drive1 back to md127. What do I need to do to make
that happen?
Thanks,
Bowie
