Really the title says it all, but with more detail:
I have a RAID 10 box set up, and one of my drives has failed (/dev/sdd). I have hot swapping enabled, so I'd like to pop the failed drive out and swap it with a new one, but I obviously want to pop the right one out, or else I could really hose my array.
Are there any tricks to knowing which is the active drive, and which isn't? Can I trust that /dev/sdd will always be the same physical drive, or can the name change inside of linux?
