I'm in the middle of an install so I create /dev/md3 to build my RAID1. I build it, install, chroot, do the work, install grub, reboot and it's md126. The problem is that the machine name changes between the install and the reboot. The change apparently has something to do with a decision to only assemble Version 1.+ superblocks with the right name when the name field matches something in the superblock. Apparently you can set up the naming as you wish using mdadm --update=3Dhomehost mdadm --update=3Dname but I don't feel confident enough yet to do it. c2stable ~ # mdadm --detail /dev/md126 /dev/md126: Version : 0.90 Creation Time : Tue Apr 13 09:02:34 2010 Raid Level : raid1 Array Size : 52436032 (50.01 GiB 53.69 GB) Used Dev Size : 52436032 (50.01 GiB 53.69 GB) Raid Devices : 3 Total Devices : 3 Preferred Minor : 126 Persistence : Superblock is persistent Update Time : Sat Feb 19 06:13:16 2011 State : clean Active Devices : 3 Working Devices : 3 Failed Devices : 0 Spare Devices : 0 UUID : edb0ed65:6e87b20e:dc0d88ba:780ef6a3 Events : 0.248829 Number Major Minor RaidDevice State 0 8 5 0 active sync /dev/sda5 1 8 21 1 active sync /dev/sdb5 2 8 37 2 active sync /dev/sdc5 c2stable ~ # - Mark
