Hello: I use linux mdraid in openSUSE for device mirroring (raid1). When looking at array properties in /proc/mdstat and mdadm -D I see arrays like: md13 : active raid1 sdc13[2] sdb13[3] 62918468 blocks super 1.0 [2/2] [UU] mdadm -D /dev/md13 /dev/md13: Version : 1.0 Creation Time : Mon Jul 15 10:44:48 2013 Raid Level : raid1 Array Size : 62918468 (60.00 GiB 64.43 GB) Used Dev Size : 62918468 (60.00 GiB 64.43 GB) Raid Devices : 2 Total Devices : 2 Persistence : Superblock is persistent Update Time : Sun Oct 11 15:17:01 2015 State : clean Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Name : pc:13 (local to host pc) UUID : xxxxxxxxxxxxxxxxxxxxxxxxx Events : 2631 Number Major Minor RaidDevice State 3 8 29 0 active sync /dev/sdb13 2 8 45 1 active sync /dev/sdc13 As you see the array has only two devices still the "number" for the devices are 3 and 2. How could I change this to have number 0 for /dev/sdb13 and number 1 for /dev/sdc13? That is, that mdstat would indicate this: md13 : active raid1 sdb13[0] sdc13[1] Also, what exactly are the meanings of "Number" and "Minor"? Which one is the so called "slot" I see at some page dealing with mdraid? I could not find info regarding this in mdadm manual or raid wiki pages.
