[gentoo-user] Resizing ext3 Partition
Marco
I am new to gentoo and so far I really like it. But now, I am running
out of disk space on my root partition (10 GB), although I have a
rather small system with fluxbox (no KDE, GNOME,...). Thought gentoo
would not waste my resources that much. Now I am thinking about how to
resize my ext3 partitions. Bellow is the output of fdisk:
fdisk -l
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda8 13832 15077 10008463+ 83 Linux
/dev/sda9 15078 19458 35182990 83 Linux
sda8 is my root partition and sda9 is my home partition where there is
plenty of space. Is there any safe way to resize with Linux tools? The
descriptions found on google did not help me a lot...
Thanks for your help!

/usr/portage/distfiles can get pretty large over time.

I'd look to see what is filling up the root partition, 10GB should be more
than enough.

Try to remount route on another directory and check which directory is using
so much. I had a similar problem asked this a couple of month before on this
mailing list. They gave this commands:
#mount -o bind / /mnt/root
#du -max-dep=1

I cleaned this directory frequently, but still running low on disk space...

I may have missed something of your configuration or partitions (did
you have a separate /usr?), but check old and useless kernel sources
from under /usr/src (and under /lib/modules if you've compiled and
installed modules).
Clean out old and unused ones. Compiled kernel sources directories can
be over 800 MB *each*. For example for my current /usr/src/linux
(which points to ./linux-2.6.28-gentoo-r5) du says 818MB. You don't
need too many of these to fill up a 10GB partition.

Good tip! cd /usr/src/linux and make clean gave me back 2 GB.
Paul Hartman
Also unmerge old unneeded kernels and remove leftovers from old
kernels found in /usr/src and /lib/modules (or /lib64/modules)

You'd be amazed how much junk collects in /var/log/portage over time

Or in /var/log. Logrotate helps there and /var/log/portage can be
cleaned up by a script that compresses everything older than 1 day (the
test helps not to "disturb" a running portage or get ugly split logs).

What I would really like to do is get rid of everything except the
most recent compile of each program in /var/log/portage -- anyone have a script to do that?

How do
you spend it?

Or just forget about the useless bind-mount and add "-x" to the "du" command.

I was only talking about getting rid of log files in /var/log/portage
where it keeps a record of each build of every program. Seems to me
only the most recent one is significant.

Check man emerge and read (carefully) --clean --depclean and --prune options.

That won't pick up space wasted by files occupying space in directories
that are used as mount points.

Why not delete everything over a week or two old? Once the package is
installed and working, you don't need the elog any more.

How often does that happen?

Not very often, but it happens in a significant proportion of the times
the root partition fills up, particularly hen running a small root. All
it needs is for an NFS mount to fail unnoticed when you boot.

If such a program has not crashed yet, it is waiting for a critical moment
