Hi Martin,

When I changed to "failed-disk 1" it works, even if I have to use the 
undocumented special force. Thank you for your help!

Now my /proc/mdstat says:

# cat /proc/mdstat 
Personalities : [linear] [raid0] [raid1] [raid5] 
read_ahead 1024 sectors
md0 : active raid1 hda1[0] 64128 blocks [2/1] [U_]
unused devices: <none>


I have some other questions:

How do I interprete the /proc/mdstat information (I understand 
personalities, but the rest)?

At what point should I change to auto-detect filesystem tag? Before or 
after I have put a filesystem on md0 and before or after I have started to 
run the raid in non-degraded mode?

To change boot device from /dev/hdc1 to /dev/md0 I guess that I use rdev to 
update the kernel (I'm booting from a floppy for the moment - make zdisk).

What is a recommended chunk-size for partitions in this sizes:

# df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/hdc1                62193     18247     40735  31% /
/dev/hdc3               124443     33999     84018  29% /var
/dev/hdc5                62193        13     58969   0% /tmp
/dev/hdc6               616636    154956    430356  26% /usr
/dev/hdc7              5233940    201492   4766576   4% /opt


Thanks once more!

That's the hint where the problem is :-)

Error in your raidtab file; you're defining disk 0 twice and aren't defining
disk 1; make it failed-disk 1 and it should work.

The file above will overwrite /dev/hda1 and will keep /dev/hdc1 unchanged.
is this what you intended?

Bye, Martin

PS: don't know about the list config, sorry
