I have a server that is remotely hosted and has a drive with over 48k
hours on it (and still running strong)...my hosting company is
providing a free replacement and I need to migrate everything over and
have the system come back up gracefully without any physical
interaction...other than one drive being stuck in the second drive bay
temporarily and the original being taken out and replaced with the
second drive when ready.
Here's what I have:
/dev/hda - 60GB old drive
hda1 Boot Primary Linux ext3 78.45
Pri/Log Free Space 1.04
hda2 Primary Linux swap / Solaris 1074.00
hda3 Primary Linux ext3 58869.01
/dev/hdc - 80GB new drive
hdc1 Boot Primary Linux ext3 74.84
hdc2 Primary Linux swap / Solaris 511.97
hdc3 Primary Linux ext3 79439.57
/etc/fstab
/dev/hda3 / ext3 usrquota,grpquota,errors=remount-ro 0 1
proc /proc proc defaults 0 0
/dev/hda2 none swap sw 0 0
/dev/hda1 /boot ext3 defaults 0 2
By my thinking...I should be able to:
mkdir /newdrive
mkdir /newdrive/{boot,newroot}
mount -t ext3 /dev/hdc1 /newdrive/boot
mount -t ext3 /dev/hdc3 /newdrive/newroot
rsync -av / /newdrive/newroot
rsync -av /boot /newdrive/boot
grub
grub> root (hd0,0)
grub> setup (hd1)
and then shutdown, pull hdc and put it in hda and fire it up.
What I'm uncertain of is the "setup (hd1)" bit....will this setup the
boot field in some way such that it will not work?
If the drives were the same, I'd feel comfortable using dd to simply
copy over the MBR, but since they are not, I'm worried about wrecking
my partition table.
Thoughts and advice are urgently needed. Thanks!!!
