Hello, I have two disks and installed FC6 via Anaconda. I expected a RAID to be setup but I'm confused about what anaconda really setup. In fact it seems (please see hereafter) that only /boot is RAID1. So is RAID fully installed ? Note: I used to previously installed (via mdadm) RAID1 under a previous FC5 so I can confirm my hardware is compatible with RAID1 Different outputs are: dmraid -r: /dev/sda: isw, "isw_cfaabdceig", GROUP, ok, 312581806 sectors, data@ 0 /dev/sdb: isw, "isw_cfaabdceig", GROUP, ok, 320173054 sectors, data@ 0 mount : /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/mapper/isw_cfaabdceig_RAIDv0p1 on /boot type ext3 (rw) tmpfs on /dev/shm type tmpfs (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) fdisk -l: Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 19189 154031220 8e Linux LVM Disk /dev/sdb: 163.9 GB, 163928604672 bytes 255 heads, 63 sectors/track, 19929 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 * 1 13 104391 83 Linux /dev/sdb2 14 19189 154031220 8e Linux LVM Thanks for any precision.
