Config a new software RAID 1 (Fedora 6)
Dear All:
I currently install fedora 6, that is working great. The problem is I bought a new sata hardisk (same size same brand), and want to do a software RAID 1. How can I do it?? I am stuck in there~~ This is my existing config [root@testmail postfix]# df -m Filesystem 1M-blocks Used Available Use% Mounted on /dev/mapper/VolGroup00-LogVol00 293613 3420 275038 2% / /dev/sda1 99 11 83 12% /boot tmpfs 502 0 502 0% /dev/shm -------------------------------------------- [root@testmail postfix]# fdisk -l Disk /dev/sda: 320.0 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 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 38913 312464250 8e Linux LVM Disk /dev/sdb: 320.0 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 38914 312571223+ 8e Linux LVM Disk /dev/sdc: 2048 MB, 2048728064 bytes 64 heads, 63 sectors/track, 992 cylinders Units = cylinders of 4032 * 512 = 2064384 bytes Device Boot Start End Blocks Id System /dev/sdc1 1 992 1999749+ 6 FAT16 Thanks for your help~~~ |
RAID1 morror in fedora
You are going to configure RAID1 morror volume based on software.
There are 2 utilities avalible to accompalish this. 1. mdadm which in inbuilt tool with redhat and fedora systems. 2. raidtools third party tool to configure software based raid. I recommend you to use mdadm, beacuse it is easy to configure and stable. I assume that you have two hdds like sda and sdb create exactly same new partitions on both hdds. so it will come to dda3 and sdb3 . next go to fdisk tool and change partition id of both new partitions to fd. fd stands for raid autodetect. Now make RAID1 (morrored ) array of thesetwo partitions. use following command to do it. #mdadm -v -C /dev/md0 -l1 -n2 /dev/sda3 /dev/sdb3 This command will create a RAID1 mirrored array called /dev/md0. Then create filesystem on RAID array. #mkfs /dev/md0 Now RAID1 array is created and is functioning properly. You can mount it now. #mount /mnt/dir1 /dev/md0 Now whatever data you write in /mnt/dir1 directory will be written on RAID1 array. To test RAID is created successfully, run following command. #cat /proc/mdstat Also #mdadm -D /dev/md0 Now create a directory /data in which we will mount /dev/md0 RAID1 array. Above command will create filesystem on it. Then add this entry in the /etc/fstab file to start morror after rebooting. #vi /etc/fstab add line as following. /dev/md0 /data ext3 defaults 1 1 Save and exit. |
