So I did googling, but all I could see was failed disks.
In my case, I have RAID mirror (mdadm) with EXT4 formatted that is healthy and both drives still up and running fine.
I have 2x 1tb SSD's but they are not like for like, one is an older model, and I stumbled across another 1tb that is like for like.
So I want to swap out the unmatching SSD in this raid mirror.
IS it as easy as shutdown, pull out old SSD, turn on, and click recover and include the new SSD?
I dont need to remove the old one first or anything from OMV?
