[gentoo-user] "Copying" between hard drives potential newbie question

[gentoo-user] "Copying" between hard drives potential newbie question

[Stuart Howard]

Hi

Long story short 
- power outage damages hard drive 
- under liveCD data can still be read [phew]
- comp will not boot from damaged hdd
- man runs to shop and buys new hdd plus UPS
- installed new hdd | /dev/hda
- old damaged hdd is /dev/hdb [3 partitions, hdb1 = /boot ext3, hdb2 =
/swap, hdb3 = /root reiserfs]

My question :-

I need to "copy" all from hdb to hda what would be the sugested route?

I created a set of similar partitions on new hda with same filesystems
then attempted a cp which indeed copied the data but machine refused
to boot, sensed that I had been too obvious so after much googling I
have looked into parted though with no sucess as yet.

If someone could recommend a fools guide to this process I would
appreciate it, as I am tired somewhat poorer and generally fed up.


stu

ps. Essential files from Gentoo system are backed up to another
machine though not full system and I am loathed to reinstall Gentoo
then copy over these files when I am sure there is a better way of
"restoring" complete system from one hard drive to another.

boot from live cd. mount new partitions under /mnt/gentoo (just like  
an install).  chroot /mnt/gentoo /bin/bash
now you're on your new drive.  grub-install /dev/new_hd_device.

If both drives are the same size

dd if=/dev/hdb of=/dev/hda bs=4096

will that get the mbr, or does he still need to do the grub-install step?

MBR is probably damaged, hence why it won't boot. I would run
grub-install just to be sure.

You could also mount your old disk and the new disk, then use
 cp -R /mnt/olddisk/* /mnt/newdisk/
(putting in the appriopriate mount locations of course)

I'd do a cp -pR if I did that, to maintain permissions.  or even use rsync, 
it'll go MUCH quicker.

Wouldn't rsync -a be better for this, or would cp -R preserve ownership
and permissions as well?

cp -a would preserve all file attributes. rsync would probably be
better.

Hi people 

MANY thanks people for the advice, after some painful time I have got
my system back or at least everything seems fine so far [typing from
opera in X].

As a record for myself and or others who may ever need this I
performed the following steps

1. Beat head on wall for not thinking to buy a UPS.
2. "broken " drive would allow access to data but bios fail reported
at attempt to boot
3. installed new drive as master old as slave
4. booted via liveCD
5. Created new partitions and filesystems similar to old 
6. mounted new and old partitions 
7. cp -prf /old /new
8. chroot /mnt/gentoo /bin/bash
9. grub-install /dev/hda
10. reboot
11. cheer

Had a few recommendations for rsync -a and a few concerns that cp
would not cp .files or maintain sufficient permissios etc but I think
that cp -prf has managed to acheive the same.

thanks again 

stu

Most UPSs below about US$400 are junk.  You'd be served just as well with
a decent surge suppressor power strip.  Don't waste your money on a UPS.

  Not if all you want is to give your home system 5 minutes to shut down
in a power failure, or to handle the occasional 30-second outage, of
which my area seems to have more than its fair share.  The saying about
"Horses for courses" is especially true here.  I don't get business DSL
with a horrendeously expensive SLA for my home ADSL service either.

Oh yes, it depends very much on the grid in your area.
I lived in the Philippines for a while where brownouts are a very common
thing---usually, you get a UPS "free" there when you buy a computer.
It's really no fun without one, and for what they have to do the cheap
lil things work very well. Their lead accus don't usually last more than
a year, but then you just get a new one for $5 or so and you're set for
another year. In Germany OTOH, hardly anybody has one, and people still
get uptimes of over a year.

WARNING: Slightly O/T

Can/has anyone used a 12V lead acid car battery as a UPS for their box?
I've got a spare one in the garage and the thought has crossed my mind .

Mick,
It can be done but is slightly more involved than just plugging in teh car 
bat. I have 3 deepcycle batts, set up for my FD base radio and 1 server using 
a 12V inverter and a trickle charger and just running the power through the 
inverter and batt all the time, that way I did not have to set up s a 
switching mechanism that would switch it over. It works well as long as you 
get a good inverter and one that is sized correctly for your power 
requirements.

It will get everything (making a copy of the physical disk surface). Due
to the fact that your machine didn't boot but data is available, I'd
think your old HDD isn't corrupted but the partition for /boot or the
MBR itself.

Try to setup grub for your old HDD too. Maybe you'll have a HDD more
now. ;)

Just a thought
