I followed these instructions exactly ( http://mybookworld.wikidot.com/forum/t-147932 ) and everything works fine up until the point where I need create the RAID array using mdadm command. I get the following error
[root@MyBookWorld /]# mdadm —create /dev/md4 —level=1 —raid-devices=2 /dev/sda4 /dev/sdb4
mdadm: Cannot open /dev/sda4: No such device or address
mdadm: /dev/sdb4 appears to contain an ext2fs file system
size=972703620K mtime=Sun Feb 7 01:23:00 2010
mdadm: create aborted
I know there haven't been many response on this lately, but if anyone has any suggestions…I would truly appreciate it…..thanks!!
