Hi,
I'm looking at replacing my mirrored root disk with the same size disk but faster RPM.
Whats the best pain free way to do this?
Can i remove the alternate, replace with a newer drive and mirror the primary.
Then boot off the alternate and insert the second disk and repeat?
Thank you.
Solved! Go to Solution.

Re: Replace mirrored root disk with same size but faster
forgot to mention its an integrity system.
or can i just add the new disk as a additional mirror, and configure it to boot off?

Re: Replace mirrored root disk with same size but faster
Yeah i've got this document.
Just wanted to make sure its exactly the same as replacing a failed disc.
Cheers.

Re: Replace mirrored root disk with same size but faster
It would be the same as a failing attached disk (therefore you must either use pvchange or lvreduce). MirrorDisk/UX does have the ability to mirror up to 3 disks, so that is another option for you as well.
Another option is DRD - Dynamic Root Disk. This allows for the creation of a copy of your boot disk at the disk level (LVM mirroring is done at the LV level).
