mdadm says "mdadm: /dev/md1 not identified in config file" when booting FC7
 
Hi all!

I have problems booting up my box after an upgrade attempt FC6 -> FC7 x86_64.

When booting up the system I get past Grub.

<snippet>
root (hd0,0)
Filesystem type is ext2fs, partition type 0xfd
kernel /vmlinuz-2.6.21-1.3194.fc7 ro root=/dev/VolGroup00/LogVol01 rhgb quiet

When booting up the system with FC7 rescue disc, I manage to mount /dev/VolGroup00/Logvol01 as /mnt/sysimage without any problems.

mdadm --detail for my arrays gives me:

My /etc/mdadm.conf looks like

<snippet>
DEVICE /dev/sd[a-z]*
ARRAY /dev/md0 level=raid1 num-devices=2 UUID=59e51400:e3912e0b:30aaf9db:450a3e09

As far as I see it the md arrays are doing fine and I have them specified in /etc/mdadm.conf?

Anyone out there that have an idea about the cause and resolution for my problem? I don't really know where to start... grub, mdadm, lvm?

Thnks in advance

RaffD Did you ever get anywhere with this problem, I have just upgraded FC5-.FC7->FC8 and have exactly the same problem.

Any ideas?
