Hi
Being lot more used of ZFS (I have some little difficulties weth mdadm and Linux software raid so far). After having done quite some extended searches, I could not find a clear answer at my question.
Is it like ZFS and mdadm is able to find back by himself where are drives when system boots ? In ZFS, I can physically reorganise drives in bays as I want without any problems (ZFS scans all drives existing in system at boot to find back its own drives). Is it the same with mdadm ?
I ask the question as I use mdadm for software with a server having a 24 bays half full. I use extra free bays to upgrade/replace existing drives in the RAID but it implies that drive letters are going to change if I reboot machine compared to what it was at previous boot (sdb instead of sda,....).
All documentations I have seen regarding mdadm always use the sdXX and never the stable UUID identifiers.
Thanks for your help,
Vincèn
