Hi
I'm having pretty unusual disk layout
i have only 3 normal partitions ( /boot and 2x / for 2 installations)
and may be about 15 partitions which are soft raids and on the top of
them I'm having LVM volumes ( i have 3 disks)
because of that i normally recompile the kernel with built in support
for raid and lvm, but for some days i tried to boot the standard smp
kernel 2418-1mdk and it wasn't that nice
it couldn't find any VG or LV , and then i found out that my
/proc/mdstat is empty
so my question
is it possible to add in mkinitrd checking for /proc/mdstat and
/proc/lvm/global and if necessary to add the needed modules
1- RAID on / is possible and supported (except if bugged)
2- LVM on / is possible but currently not supported (AFAIK, drakx
will not allow you to do so) ; there are things like
vgcreate to do AFAIK, etc
i know that
and i didn't mention anything about / ( my / is normal partition )
the thing is that mkinitrd checks only for /etc/raidtab and not for
/proc/mdstat
so it doesn't add the raid modules and thats the cause for missing PV's
( raids) and VG's
after installing ( and booting ) the 2418-1mdk i had no raid and lvm
devices
and i had empty /proc/mdstat and /proc/lvm/global
that's what i have with raid compiled in
