Hello, I have a server working on centos 5.7-64 minimal installation. I have 3 separate physical drives: 120 gb ssd, 2x 3tb disks for storage. My linux installation is on ssd disk, and I want to make raid 1 for these two 3tb disks and store data, like under /mnt/data. Can you please tell me the path how this is possible? Thanks for your help! Best regards, Here are some output of commands I ran for more data: [root at CentOS-57-64-minimal tmp]# fdisk -l | grep '^Disk' Disk /dev/sdb doesn't contain a valid partition table Disk /dev/sdc doesn't contain a valid partition table Disk /dev/sda: 120.0 GB, 120034123776 bytes Disk /dev/sdb: 3000.5 GB, 3000592982016 bytes Disk /dev/sdc: 3000.5 GB, 3000592982016 bytes [root at CentOS-57-64-minimal tmp]# df -l Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda3 113695432 1427792 106537696 2% / /dev/sda2 520136 23576 470348 5% /boot [root at CentOS-57-64-minimal tmp]# fdisk -l Disk /dev/sda: 120.0 GB, 120034123776 bytes 64 heads, 32 sectors/track, 114473 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes Device Boot Start End Blocks Id System /dev/sda1 2 2048 2096128 82 Linux swap / Solaris /dev/sda2 2049 2560 524288 83 Linux /dev/sda3 2561 114473 114598912 83 Linux Disk /dev/sdb: 3000.5 GB, 3000592982016 bytes 255 heads, 63 sectors/track, 364801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sdb doesn't contain a valid partition table Disk /dev/sdc: 3000.5 GB, 3000592982016 bytes 255 heads, 63 sectors/track, 364801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sdc doesn't contain a valid partition table
