I am planning to move from one HD to another I need a bit of feedback. I am partitioned as follows:
sda1 /boot (Linux Partition) 256M
sda2 LVM PV (Linux LVM Partition) 20G
I was planning to.....
1) attach the new HD
2) boot to a rescue CD
3) partition the new HD exactly how the old one is
Just dd the whole drive. Saves steps 4-6.
4) dd if=/dev/sda1 of=/dev/sdb1
5) dd if=/dev/sda2 of=/dev/sdb2
6) make the new HD bootable
7) disconnect the old HD
8) boot
My questions...
- Is this basically the right procedure?
- Do I need to boot to the rescue CD or would single user (or emergency) mode be good enough (in step 2)?
- Exactly what steps are required to "make the new HD bootable"?
- Is there a way for me to make the old hd "unbootable" so I can leave it in, but make sure it's the new one that boots?
Why?
A problem with having both drives present arises from the way RH has
been mounting drives by label for years. My early experiences was that
the wrong filesystem gets mounted.
I think having two of these isn't good, too:
/dev/VolGroup00/LogVol00
Note that the new drive cannot be smaller.
Note that if the new drive is larger, you can use the extra space as new
partition(s) and/or expand the adjacent partition. If you google my name
and resize2fs you will find my earlier writings on the subject.
Thanks for any feedback,
Tom
