hi; um no i havent had teh same problem with my harddrives and i have them 
both teh same. did you not want to format teh other harddrive? i was just 
thinking that if you put teh same filesystem on there as you did on teh one 
with FC2 that fedora might have not have a heart attack when it tries to 
read it? really your question isnt really clear. can you get into teh fedora 
OS or is it not loading at all? i'd like to give more useful comments if at 
all possible.

Subject: Raid question

Hi,

Does anybody encounter problem configuring software RAID 1 with FC2?

I have 2 identical HDDs, the 1st one where I install FC2 and the 2nd HDD 
is

unformatted. Here is the error messages I got:

# mkraid /dev/md0

handling MD device /dev/md0

analyzing super-block

disk 0: /dev/hda, 29316672kB, raid superblock at 29316608kB

disk 1: /dev/hdc, 29316672kB, raid superblock at 29316608kB

mkraid: aborted.

(In addition to the above messages, see the syslog and /proc/mdstat as 
well

for potential clues.)

Here is error from log file:

kernel: md: could not lock hda.
kernel: md: error, md_import_device() returned -16

# cat /proc/mdstat

Any comments and help would be appreciated. Thanks.
