 Posted: Sat Oct 30, 2010 10:37 am Post subject: gentoo system old with rootfs 100% used? |
 |
|
Hi,
I came to a point where "startx" doesn't go through. It complains about "not enough space".
Command "df" reveals that rootfs which phisically resides on /dev/sda3 is full.
I removed all of the distfiles from /usr/portage/distfiles and was able to gain 4% space.
I suspect that somethning might have happen during my last compilation: the power went off, with no UPS.
Where to look for some posssible dispersed files?
What should I do to get thing right?
| Code: |
df
Filesystem 1K-blocks Used Available Use% Mounted on
rootfs 96132968 86728084 4521528 100% /
/dev/root 96132968 86728084 4521528 100% /
rc-svcdir 1024 112 912 11% /lib64/rc/init.d
udev 10240 224 10016 3% /dev
none 1547352 0 1547352 0% /dev/shm
/dev/sda1 101089 47885 47985 50% /boot

Boot from a liveCD and run fsck.
Make sure all logs are rotated so they won't go out of hand.
Clean up /var/local/portage.
Remove unused kernel sources. |

also a nice space killer: mysql bin-logs

What normally goes here? I do not have a /var/local at all.
Another space eater: $PORTAGE_TMPDIR, which defaults to /var/tmp/portage. If you get interrupted during a compile, the partially completed work can be left there. (This might have been what Jaglover meant to mention, but I will add it in case he had something else in mind.) |

Thanks for correction, Hu.  I meant /var/tmp/portage indeed.
I was posting before my first cap of coffee this morning.  |

Happy to help. However, if you need an entire cap of coffee in the mornings, I really hope you get a good discount on your brew. |

agrypa1,
if you're still looking, there are heaps of ways of liberating space, besides deleting the obvious.
IF you have a spare partition of device of some sort (maybe a usb flash drive) you could move a folder like /usr and/or /var or /home out of your system partition; just remember to make the new entry in /etc/fstab.

The deletion of var/tmp/portage helped significantly, 8% storage gain.
I am now thinking of adding a new hardrive and migrate into lvm. I hope to find some goog howto on how to convert non-lvm system into anlvm one.
thanks all for the suggestions

If you are not converting in place, then just make filesystems on the destination drive and copy the files over via a tar pipeline: | Code: | cd /mnt
mkdir old new
for fs in '' usr var home; do
mount --bind /$fs old
mount /dev/mapper/lvm-${fs:-root} new
tar -C old -c -f - . | tar -C new -x -f -
umount old
umount new
done
rmdir old new |
