Public bug reported:
I forgot to specify the new MD device to mdadm when creating a new
array, resulting in an error message:
# mdadm --create --level=raid1 --chunk=64 --raid-devices=2 /dev/hdb /dev/hdc
mdadm: You haven't given enough devices (real or missing) to create this array
but also resulting in the device file for "/dev/hdb" going AWOL:
[EMAIL PROTECTED]:~# ls -la /dev/hd*
brw-rw---- 1 root cdrom 3, 0 2008-04-10 18:52 /dev/hda
brw-rw---- 1 root disk 9, 127 2008-04-11 09:43 /dev/hdb
brw-rw---- 1 root disk 22, 0 2008-04-10 18:52 /dev/hdc
brw-rw---- 1 root cdrom 22, 64 2008-04-10 18:52 /dev/hdd
Please check arguments before doing anything to files or devices :-/
2.6.2-1ubuntu2, ubuntu gutsy.
cheers,
Andras
