Hi, I did a fresh install of Sarge, updated the kernel to 2.4.26. then did: platinum:~# mdadm -C /dev/md0 --level raid1 --raid-disks 2 missing /dev/hdc1 mdadm: /dev/hdc1 appears to contain an ext2fs file system size=117218240K mtime=Wed Dec 31 18:00:00 1969 Continue creating array? y mdadm: SET_ARRAY_INFO failed for /dev/md0: File exists Anyone know why am I getting this error? This is the first time (for this install) that I'm trying to build a raid. Where does this file exist? On my system disk or on the second disk I'm trying to build the raid on?
