Okay I am trying to setup RAID on FC5, almost all the examples that I have found are for raidtools2, however FC5 does not have raidtools2. so i have been trying to use mdadm to do it, but I keep getting errors. So anyway I need some help in setting up RAID to work on my system. Here is some preliminary information. ################################################## 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 6540 52428127+ 83 Linux /dev/sda3 6541 13067 52428127+ 83 Linux /dev/sda4 13068 19457 51327675 5 Extended /dev/sda5 13068 13328 2096451 82 Linux swap / Solaris /dev/sda6 13329 19457 49231161 83 Linux Disk /dev/sdb: 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/sdb1 * 1 13 104391 83 Linux /dev/sdb2 14 6540 52428127+ 83 Linux /dev/sdb3 6541 13067 52428127+ 83 Linux /dev/sdb4 13068 19457 51327675 5 Extended /dev/sdb5 13068 13328 2096451 82 Linux swap / Solaris /dev/sdb6 13329 19457 49231161 83 Linux ################################################## df -h Filesystem Size Used Avail Use% Mounted on /dev/dm-6 46G 1.6G 42G 4% / /dev/dm-1 99M 9.2M 85M 10% /boot tmpfs 473M 0 473M 0% /dev/shm /dev/dm-3 49G 181M 46G 1% /home /dev/dm-2 49G 233M 46G 1% /var any other questions please ask away. I had been told to use fdisk to change the ID of the drive and to make it a "Linux raid auto detect" and then do that on the other disk. That seemed to be okay, but then that was some instructions for raidtools2. mdadm I couldn't even get past the first one as it couldn't find sda5 or sdb5, it told me to use the swap partition is there is an increased chance of data loss with RAID 0, to use a partition that does hold any important data. so as you can see I am right now floating along and I need some help. If you have a better way I am all ears.
