Re: [arch-general] how to migrate installs between hard drives?
I tried a simple 'cp -av' [...] and find that everything is set to root / root if you want to preserve permission, you need to use -p too. Do you know that there exists something called the man pages (the manual pages) for each command on your system ? so if you run 'man cp', you get a list of all the options of cp and how it works. no offense, i am still reading them every day. i think at this point, you really need to read them carefully. otherwise at every new question you will ask you will get back a RTFM.
Re: [arch-general] how to migrate installs between hard drives?
Thanks solsTiCe, no offense taken, but I am one of the people that RTFM. Plus, the -a option gives you -p anyways, so ownership, mode and timestamps are kept by default. This is just a weird coincidence that I can't explain. I've been able to copy a drive before, but never with this much difficulty.

Re: [arch-general] how to migrate installs between hard drives?
I think NTFS is the issue. I don't think that it supports the same permission and ownership capabilities as native *nix file systems. For example, when I mount my windows partition, I have to specify a gid and a umask, else I don't have permissions to access it.

If the NTFS partition is mandatory, and you're doing a backup, you could just tar everything. It will sure preserve every attribute.

I'd recommend doing as was suggested (using tar) or some similar archiving method or just use another filesystem for the big drive -- I like to format all of my external drives with a large partition (most of the disk) that is ext3 and a very small partition on the beginning of the disk (20 mb or so) that is fat32 which contains the ext3 filesystem driver for windows machines so that they can install it if necessary to access the other partition on the disk. signature.asc Description: OpenPGP digital signature

Why, out of curiosity? dd copy the data of the raw device. i.e the files but also the filesystem data and metadata. which you don't really need or wish to copy to another partition/disk. i said it's the worst, not that it does not work. but you have to take extra step after you have used dd (to resize filesystem and so on)...

Re: [arch-general] how to migrate installs between hard drives?
Yes I would dd (or ddrescue or dd_rescue - the rescues give you progress output) the whole drive, not the individual partitions. Then just use Parted Magic Live CD or GParted Live CD and expand the partitions. I've done this many many times without issue.. and usually you don't even have to repair grub afterwards... Another solution is using Clonezilla (use disk to local disk), (which I think might even have a switch to expand at the same time but I've never used that option) and then use Parted Magic Live CD which has Gparted in it to expand. BTW Parted Magic Live CD has Clonezilla as well so it's really all you need (I'm sure all the dd tools are on it too) -Jon - Original Message From: Will Siddall will.sidd...@gmail.com To: General Discusson about Arch Linux arch-general@archlinux.org Sent: Wednesday, July 29, 2009 6:22:08 PM Subject: Re: [arch-general] how to migrate installs between hard drives?

Re: [arch-general] how to migrate installs between hard drives?
Hey everyone, After several attempts, I'm still back to trying to resolve this. To explain in more detail, I had a 100G hd with a root partition (with my Arch Install), a data partition and a swap. I managed to run dd on both partitions and in the new hd (200G) apply both. But that only worked partially due to the fact that it copied the ratios of file sizes rather than the actual file size... Copying 80G of data from a 30G partition doesn't quite sit well with me. Next step was to mount the iso images and copy the files. That's what I was in the process of doing of my last message and it worked... until I went to restart and update. What I found that was that my permissions and ownership info was not kept. Because of this, as soon as I went to update anything, the installers would run, but just delete the files (it deleted pacman and yaourt so I had to find a way to compile pacman to install again... until it tried to update all of my bin tools... then everything was gone). Now following all of your suggestions, I tried rsync -arpol and a variety of different other settings but it still doesn't keep the permissions. I tried running tar on the partition, still not working. Does anyone have any other suggestions or know why I'm having this problem? I'm going to try to wipe out the new hard drive and run dd on the whole 100g disk and reapply it to the 200G disk. And by the way, I'm running a ubuntu livecd to run these processes.

So, if I copy my root partition that started as a 40G partition with 90% used and now I have a 60G parition, the used portion will be kept at 90% so, it'll show something like 50G of data... which doesn't make sense. What about a dd followed by using parted/gparted or whatever to resize things as necessary? They have a good LiveCD too that you should be able to use to get things copied and then resized. I think gparted even has built in support for copying partitions; not sure if it can do it across drives. -Dan

Re: [arch-general] how to migrate installs between hard drives?
Another option is using rsync to copy all files to the other disk. This can be done with a temporary server storage if necessary. If you use the -a switch, it keeps permissions intact and works perfectly for Linux, not for Windows, but who uses that anyway? ;) Greetings!

Okay: A - The disk that already has an installation but is smaller B - The disk that that you want to put the installation on if you dd A onto B, B will get the partition structure from A and appear smaller. However, you can edit the partition sizes using gparted like Dan said, and make the partitions fill up the whole B disk. -- Alexander Lam
Re: [arch-general] how to migrate installs between hard drives?
Thanks everyone for their suggestions. I'm really tempted to give each of these methods a try. For the time being, I did get it finished. Without having to take all the hardware apart, I just made a clean base install of arch onto the disk and use the livecd, mounted the iso and copied everything over. I'm up and running, but whenever this happens again, I'll be sure to give your suggestions a try (and at least it's documented). Thanks so much.

Haven't had any problems yet. As Erwin wrote, you can use the -a switch and also the -v and --progress. I do this booting with a LiveCD/USB image - rsync to the temp server/system - rsync back. Once you rsync back to your laptop with the new drive. Boot with the LiveCD/USB image and check things like fstab or /boot/grub/menu.lst because the ID will have changed. Maybe you have to boot a couple of times with the LiveCD/USB image because you forgot to edit this or that file. HTH Rafa On Sunday 26 July 2009, Nergar wrote: I think clonezilla could help you here.

Re: [arch-general] how to migrate installs between hard drives?
Will Siddall 提到: Is there something I'm missing in the second instance that I didn't change a file that should be changed? Is there a better way of copying the partitions so I don't run into this problem? Thanks, Will Not only dd, you could also simply use archive mode of rsync or cp. I've done this before, and the system I'm using now is migrated from a 250g to 500g. At that time I used rsync and skipped directory /dev, /proc and /sys. After a successful re-setup of grub, the system boots like a charm. regards, b4283.

However, you can edit the partition sizes using gparted like Dan said, and make the partitions fill up the whole B disk. You can also dd a single partition from A onto B, then run fdisk, DELETE the partition and recreate it with bigger size, then run resize2fs to extend the file system to fill the whole new partition. (Of course resize2fs works only with ext2/ext3/ext4). Cheers, Sergey
