Bug#433210: Debian-installer should include /dev/md0, /dev/md1 (plus mdadm, MAKEDEV?)
Package: debian-installer
Version: 20070308
While trying to perform some rescuing of a Debian Etch x86 system running
with root-on-md (RAID1) (plus some other partitions with md RAID5),
I tried to use the USB Debian Installer.
This was not as easy as I'd think it would be, because there's no
/dev/md0 accessible from the installer shell. I actually got mdadm
installed by starting the manual partition editor (guess I pulled in
some md installer package) but there were still no /dev/md[0-9] device
nodes around. Also I couldn't find any MAKEDEV script so creating them
were not trivial. Finally I managed to put the correct md device files
on a mountable file system and "cp -a" them into the running installer
shell.
So in summary, I'm submitting this bug report in the hopes that rescuing
md systems can be made easier with the next version of the debian
installer.
PS: I also got a whole lot of scary messages in 'dmesg' when the
debian-installer automatically tried to mount every partition to look
for the .ISO file (it tried to mount the raw devices, which are part of
undetected MD arrays). Hopefully the mounting done by the .ISO detector
doesn't un-sync the arrays (does that make sense?)
