Dedicated server with 2 drives as RAID1


Hi
I am sort of newbie to linux, using hit & trial method to learn something new

Anyways I have just aquired dual drive (250GB each) Pre-Configured dedicated server which was installed using the install link provided in panel.

I have installed webmin/virtualmin to easyfy things

I want to use the 2 drives for RAID1

Below is the output of few commands I know

Quote:

[root@server ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg-root 225G 25G 189G 12% /
tmpfs 1.9G 0 1.9G 0% /dev/shm
/dev/sda1 243M 68M 162M 30% /boot
/dev/mapper/vg-tmp 976M 4.1M 921M 1% /tmp
[root@server ~]# mount
/dev/mapper/vg-root on / type ext4 (rw,noatime,grpquota,discard,usrquota)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sda1 on /boot type ext2 (rw)
/dev/mapper/vg-tmp on /tmp type ext4 (rw,noatime,discard)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

Usually, yo have to setup the drives with RAID during installation.

I might be not reading what you have but if you have lvm you could move stuff around maybe and add the second drive to the array. Pretty sure I recall that from lvm stuff read long ago.

Actually this server is pre-configured and is installed by clicking the link

@jefro
I think it is LVM and there is one virtual group in it named 'vg' which is 232.81GB in size. But I don't know how to move stuff, should I have to create another virtual group oe what else.

So is there a /dev/sdb? I'd check that. If there is then both disks are being presented to the OS.

madam would probably be the facility that you are after but it is definitely easier to set-up during installation, rather than post installation. Alternative if the physical box supports it, you could set-up the RAID1 on a hardware or embedded RAID. My personal preferences tends to be hardware -> software -> embedded. I'd only use embedded as a last resort, since they tend to be flaky from experience.
