[gentoo-user] Migrating hard drives
I'm about to switch from one SATA hard drive to another and I'm planning on going through the normal installation process except for copying over the data on each partition of my old drive to the corresponding partition on my new drive. Is there anything to watch out for? Pitfalls to avoid, etc? - Grant

Is there anything to watch out for? Pitfalls to avoid, etc? I don't think so... it depends on what drive it is and how it is partitioned... if there's just one partition then it should be as simple as formatting the new copy and cp -a /olddrive /newdrive If it's your boot drive and has boot/root/home/and so on partitions then you'll need to pay attention to the partition numbers as they very well may be different when you partition the new disk. Be sure to edit the grub config fstab to make sure it's all pointing to the right place. An alternative in that case would be to use dd to clone the old drive onto the new one, then use something like parted (gparted/qtparted for GUI) to resize the partitions to fit the new disk, assuming the filesystems in use allow for such a thing. The disadvantage to this is you are closing fragmentation and everything else, and if the new drive is a lot bigger than the old, you may not have enough inodes in your fileystem. Whenever I do that, I boot from a live CD and copy the drives as above, then plug the new drive into its official cable, boot from live CD again and make sure the partition numbers are right, install grub (if boot drive), reboot and everything is done. If anything went horribly wrong, you've always got the original drive that you can go back to and try again. Good luck :) Paul

Hmmm, a bit of an abstract description (what is meant by data?) of the issue with a broad question, but here goes... * If you plan on overwriting the old drive, make a backup. * Don't overwrite /etc but keep a copy of it around (e.g. /root/old_etc) * Keep a copy of your old world file, /etc/portage, etc. so you know what's installed. * If you're keeping both drives don't forget to update your grub/lilo config. * You might want to re-label your old partitions (if they're labeled) to avoid confusion. * Be careful of changes of uid/gids in system accounts with the new install. When creating new users you might want to be sure their uids/gids match. * Again, a backup is your friend. HTH, -a

It is curious that this is very OS dependent. In FreeBSD, with cp, holes always go away, using tar, or better dump/restore is a way to keep all file attributes. In Linux, cp -a seems to be better for archives than tar, because it preserves these properties better, even across devices. Hmm..., with tar, -p will preserve permissions and -S will handle sparce files efficiently. -W will additionally verify that that data was archived without corruption. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

So, instead of your kernel must not be 64bits, maybe it would have been clearer to say I suspect you are not using a 64-bit kernel; if you were, it would not have this problem. :) Paul

Then when it's time to backup you can stop the slave and make a backup without disturbing the master instance. Aha! Never done this. How would you go about it? To be honest I've never attempted it. Most of my recent installations have been large enough where having an actual backup server was a requirement. However Gentoo does include the /etc/init.d/mysqlmanager startup script. You'd need to muddle through it and figure out how to separate the pid files, suffixes, conf file enough to make it work. When finished you'd want you slave instance running only on localhost and say port 4306. Then you tell it your master is localhost port 3306. Mysql likes to assume localhost is always a socket so you might want to add an entry into /etc/hosts to trick it into connecting via tcp, but I'm not sure if it matters. something like 127.0.0.1 localhost mastermysql.yourdomain.com Additionally be careful with the conf setting in your Mysql installation. I think the standard Gentoo conf uses 64MB of RAM. If you've modified your production copy make sure you keep the slave copy small. You might need to raise the keybuffer in your slave if you have large indexes. I suspect you can ignore most of this in a web application environment, but it's good stuff to keep in mind later on. I'm moving this week and with the holidays I've got no time to try it, but if you have question after the first I'd be happy to help you sort it out. kashani

Re: [gentoo-user] mplayer-1.0_rc2_p28058-r1 USE dvdnav
On Sat, Dec 20, 2008 at 02:16:09AM +, Penguin Lover Stroller squawked:
Anyone see what I'm doing wrong here, please?
Yes. See below.
I can't seem to get mplayer to accept the dvdnav USE flag, which is always
(-bracketed) out when I pretend to emerge it:
snip
Yet the ebuild seems to say:
dvdnav? ( =media-libs/libdvdnav-4.1.3
=media-libs/libdvdread-4.1.3 )
...
if use dvdnav; then
myconf=${myconf} --with-dvdread-config=/usr/bin/dvdread-config
\
--with-dvdnav-config=/usr/bin/dvdnav-config \
--disable-dvdread-internal
elif ! use dvd ! use dvdread; then
myconf=${myconf} --disable-dvdnav --disable-dvdread
use a52 || myconf=${myconf} --disable-liba52 \
I think I have emerged the appropriate versions of libdvdnav libdvdread:
$ eix -I -c libdvd
[I] media-libs/libdvdcss (1.2.9-r1(1.2)@10/10/08): A portable abstraction
library for DVD decryption
[I] media-libs/libdvdnav (4@12/20/08): Library for DVD navigation tools
[I] media-libs/libdvdplay (1@07/07/07): A simple library designed for
DVD-menu navigation
[I] media-libs/libdvdread (4.1.3...@12/19/08): Library for DVD navigation
tools
Found 4 matches.
$
This is a mostly x86 system, with only a handful of packages manually
keyworded or unmasked.
libdvdnav-4.1.3 is keyworded ~x86, while mplayer-1.0_rc2_p28058-r1 is
keyworded x86. The USE cannot be satisfied. See
/usr/portage/profiles/base/package.use.mask, somewhere near the
bottom, there is a bit about dvdnav being masked. I think you can try
use unmasking the flag: add a line to /etc/portage/package.use.mask
media-video/mplayer -dvdnav
should do the trick.
