I see the same thing here. I'm in the middle of an install so I create |
20 |
/dev/md3 to build my RAID1. I build it, install, chroot, do the work, |
21 |
install grub, reboot and it's md126. The problem is that the machine |
22 |
name changes between the install and the reboot. |
23 |
|
24 |
The change apparently has something to do with a decision to only |
25 |
assemble Version 1.+ superblocks with the right name when the name |
26 |
field matches something in the superblock. |
27 |
|
28 |
Apparently you can set up the naming as you wish using |
29 |
|
30 |
mdadm --update=homehost |
31 |
mdadm --update=name |
32 |
|
33 |
but I don't feel confident enough yet to do it. |
