Hello, I am using Ubuntu Hardy with 3x500GB drives and the following RAID configuration : /boot is on a 100MB RAID1 / is on a 30GB RAID0 /home is on a 906GB RAID5 I want to replace the 3 drives by 3 1TB drives. Here is how I planned to do it : 0- Backup my /home on some external disk. 1- backup / with something like : sudo tar cvpzf /backup.tgz --exclude=/media --exclude=/proc --exclude=/lost+found --exclude=/backup.tgz --exclude=/mnt --exclude=/sys --exclude=/home / mv /backup.tgz $1 2- Replace 1 disk 3- Boot and let the RAID1 and RAID5 reconstruct 4- Replace 1 other disk 5- Boot and let the RAID1 and RAID5 reconstruct again 6- Replace the last disk 7- Boot and let the RAID1 and RAID5 reconstruct one last time 8- Boot and restore the backup on the RAID0 / partition. 9- Resize the /home partition to 1 TB. I suspect there will be a problem replacing the primary disk, but I guessed that I could solve this simply by changing which is the primary disk in the BIOS. Is there any other problem that will or could happen ? For example, I am not sure if the raid manager is on the /boot partition or on the /. I guess if it is on /, it won't work at all since the raid manager itself won't be able to run ? Also, is it possible to boot and access a command line to restore the backup with a failed / partition ? I am also unsure about how I should proceed to resize the /home partition. Is this done through mdadm ? Please enlight me on any problems that I will have.
