A friend 'Sarlok' and I are busy installing his new 80gig harddrive and would like to move his gentoo installation, to avoid recompile and un-necessicary setup, we've try'd simply using 'cp -pRd' to copy each individual folder into the root of the new drive because it choke's on /proc and a couple of other things, the system actually boot's properly, but thing's like xterm and sshd dont work properly... perhap's theres a better way of going about cloneing his installation

thanks in advance

I have to say I love this phrase "like xterm and sshd dont work properly". What does properly mean? Can you use them or do they fail with a certain error?

The best way of moving the root partition to a new drive would be to use tar or cpio. It is not a straight forward issue and it may actually give you problems. The only thing that I can gurantee will work, is to use a decent backup program and then restore from the backup onto the new drive.

Not working, meaning xterm won't start as a non-super user. As far as I can tell, every user should have permission to start it, the group files and read/write/owners of xterm file, and the folder it's in are all the same as on my other working drive (the one I've booted from at the moment).

As far as ssh goes, it freezes on the clients end if they try and connect to my pc after they enter their password. That requires killing the process to stop it.
Those are the only things we've noticed so far that are messed up, allthough I would like to make sure it all copys fine so that everything works.
Same thing happens trying to et to it from my PC.

I'd rather find a way to copy everything properly than get these individual things working again. cp almost worked, but it can't seem to get the permissions and owners right still. either all owned by root/root, or 0/0.
That or it keeps giving me "No room left on device" when there's still 32 gigs free.
fschk doesn't give any errors on bootup or when it's run either.

Any sort of backup apps you could suggest that I could emerge? I found 'flexbackup', a backup script... but it's a little on the scary side.

I'll get back to googleing, but if you reply before I find something...

Well, here's an easy way to copy partitions that has always worked for me. Boot from the livecd. Mount both the old and new partitions. Then run the following.

Am I right in assuming that cpio will work if the partitions aren't identical in size? dd, as far as I understand, will replicate them *exactly*, which is not what I want.

My plan is to put both HDs in, new being /dev/hdb and then copy /dev/hda1 -> /dev/hdb1, /dev/hda2 -> /dev/hdb2 and so forth. but the matching /dev/hdb* will be bigger (in general) than it's hda counterpart.

Will cpio do this?

But of course.

I tried doing this with a 2004.3 CD, but I get "cpio - command not found" trying. Am I using the wrong CD for this?

Apparently cpio isn't included on the 2003.4 cd. You could also accomplish this with rsync, which is what I do for backups.

Note: rsync isn't included on the CD either, and using tar gives me alot of "tar: ./path/file: socket ignored". Is it really safe trying to boot the new disc even if I get this?

I have, it's part of my standard harddrive replacing spiel, I think you can find it if you search deep enough in the forums. It hasn't given me any issues. Why would it be worse than a bit for bit dumb copy like dd? Maybe it will take longer but it preserves all the important info.

i tried it yesterday and ran into problems when it tried to copy /mnt.

I want to move from one hard drive 36gig to another 73 gig.

I have partitioned the second disk

/dev/sdb1 will be boot 73MB
/dev/sdb2 will be swap 300MB
/dev/sdb3 will be root rest

I was going to boot up the live cd and mount the the root part /mnt/oldroot /mnt/newroot and cd /mnt/oldroot, cp -ax * /mnt/newroot. (boot also)

Will this work ok?

I will just have to make some changes to grub.conf then?

Thanks

In trying to do the cp -ax, I received some SCSI IO errors. Is there something else I should try?

SCSI error : <1 0 1 0> return code = 0x80000002

that error is repeated a countless number of times
