Hello,
I'm having trouble running mkraid with the above setup. I'm not on the
list, please be sure to email [EMAIL PROTECTED] on responses. Thanks!
Here's a bunch of diag info, feel free to ask for more:
[root@sadia rc.d]# mkraid /dev/md0
handling MD device /dev/md0
analyzing super-block
disk 0: /dev/sdb1, 36081958kB, raid superblock at 36081856kB
/dev/sdb1 appears to contain an ext2 filesystem -- use -f to override
mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
*** so, I run:
[root@sadia rc.d]# mkraid --really-force /dev/md0
DESTROYING the contents of /dev/md0 in 5 seconds, Ctrl-C if unsure!

trying to run mkraid:
