RAID devices typically are named /dev/md0 for the first, and so on; or /dev/md/0 for the devfs naming scheme. (md stands for multi-disk; the software RAID driver in linux is called "md"). In any case the first raid device (md0) has major number 9 and minor 0. > Ls -l /dev .... My guess is /dev/sda is for RAID1 and /dev/sdb is > for RAID5.

See fdisk(8). This option does not do what you think it does. > May I know exact sysntax of commands to partition and create 2 > filesystems on my 7 RAID disks. Your RAID device must be divided into partitions when it is created, or not at all. The proper way to do this is to have one RAID partition, and then put LVM on it. The LVM partition can then be further divided into partitions. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
