Binary package hint: mdadm
I installed Ubuntu 10.04 on a software (throughout the description I'm talking about softraid) raid1 array, with the alternate installer. It boots, it works, all's well.
Now I wanted to create some new raid arrays and I experience the following:
If I create it with the 1.2 superblock AND I give it a name
"#mdadm --create /dev/md1 --metadata=1.2 --name=TEST --level=1 --raid-devices=2 /dev/sda1 /dev/sdb1 -> the array is created
"#mdadm -Es | grep md1 >> /etc/mdadm/mdadm.conf" -> the array gets the name "TEST" and device name "/dev/md/TEST" and upon doesn't start.
Instead an inactive array called md_d127 (further arrays are named md_d126, md_d125) appears, in /proc/mdstat grabbing one of the components.
Trying to assemble the created array "#mdadm --assemble --name=TEST" (or --assemble /dev/md/TEST) results in a degraded array with only the other component in it.
Stopping the md_d127 array and then assembling the TEST array usually works, but last time I tried it failed.
The following device files are present in /dev (md0 has the system on it):
# ls /dev/md*
/dev/md0 /dev/md_TEST1 /dev/md_TEST3
/dev/md_d127 /dev/md_TEST2 /dev/md_TEST4
/dev/md:
TEST TEST1 TEST2 TEST3 TEST4
If I create a default raid1 (I've tried naming it too, but I guess that's unavailable, with a v0.9 superblock), or one with a 1.2 superblock, but no name given, they all get assembled upon reboot.
