Using my Mirror disk to boot up.


This is my Filesystem:

Filesystem Size Used Avail Use% Mounted on
/dev/md0 9.7G 6.6G 2.7G 72% /
none 189M 0 189M 0% /dev/shm
/dev/md2 103G 98G 289M 100% /home

and this is mirror settings:

Personalities : [raid1]
md1 : active raid1 hda2[0] hdd2[1]
512000 blocks [2/2] [UU]

md2 : active raid1 hdd3[1] hda3[0]
109298112 blocks [2/2] [UU]

md0 : active raid1 hdd1[1] hda1[0]
10240128 blocks [2/2] [UU]

The problem i am facing is my mirror disk does not seem to boot up when i swap hard disk to test where my mirroring disk is working. The only thing i see was this 'LI' in the monitor and hangs there.

I am quite new to mirror disk. PLease do advise me. Thanks

I'm not 100% sure here, but when you mirror a disk, it only mirrors the partitions, you still need a boot loader. I assume your probably using Grub, you will need to install GRUB to the mirrored disk as well. Then if your simulating a failure by removing the first disk, the second should work.
Good luck..

Thanks for the tips. It works. I was using the super grub loader to install onto the mirror disk.
