Hi,
I made a digital picture frame out of an old laptop and use a 4GB CF card for the root file system. I'm trying to update the kernel, but for some reason I get a "No space left on device" error:
| Code: |
frame ~ # emerge gentoo-sources
Calculating dependencies... done!
>>> Verifying ebuild Manifests...
>>> Emerging (1 of 1) sys-kernel/gentoo-sources-2.6.29-r5 to /
Traceback (most recent call last):

File "/usr/bin/emerge", line 6395, in action_build
retval = mergetask.merge(pkglist, favorites, mtimedb)

OSError: [Errno 28] No space left on device: '/usr/portage/distfiles/.locks/.genpatches-2.6.29-7.extras.tar.bz2.portage_lockfile'

The weird thing is that I should have enough free space:
| Code: |
frame ~ # df -hl
Filesystem Size Used Avail Use% Mounted on
rootfs 3.8G 2.0G 1.7G 54% /
/dev/root 3.8G 2.0G 1.7G 54% /
udev 10M 96K 10M 1% /dev
shm 110M 0 110M 0% /dev/shm
rc-svcdir 1.0M 68K 956K 7% /lib/rc/init.d
tmpfs 16M 4.0K 16M 1% /tmp
tmpfs 16M 96K 16M 1% /var/log
tmpfs 16M 0 16M 0% /var/lock
tmpfs 16M 0 16M 0% /var/tmp
|
| Code: |
frame ~ # cat /etc/fstab
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/hda1 /boot ext2 noauto,noatime 1 2
/dev/hda2 / ext3 noatime 0 1
tmpfs /tmp tmpfs defaults,nosuid,mode=1777,size=16m 0 0
tmpfs /var/log tmpfs defaults,nosuid,mode=1777,size=16m 0 0
tmpfs /var/lock tmpfs defaults,nosuid,mode=1777,size=16m 0 0
tmpfs /var/tmp tmpfs defaults,nosuid,mode=1777,size=16m 0 0
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
|
Does anyone have an idea what could be the reason for this problem?
Any tips are appreciated.

| Also, you have /var/tmp set to a tmpfs space of 16M. Since that's the area Portage unpacks and compiles things, that's not likely going to be enough space.(also, unlike /tmp. stuff in /var/tmp is supposed to persist across reboots, according to FHS anyway) |

krinn, salahx
Thanks for your replies, looks like I have re-create the partition with a higher inode/size ratio.

Thats a good point, however, I have PORTAGE_TMPDIR set to a directory that is not on a tmpfs partition. Actually, what I do to update the frame is to export "/" via NFS and mount it on a more powerful computer. On the more powerful computer, I chroot into the mounted root directory of the frame and mount a large tmpfs (4GB or so) over the portage temporary directory. Then "emerge -ua --deep system world"  .
I will look into the your point that /var/tmp should be persistent, so far I haven't encountered any problems. |
