[gentoo-user] /boot without space.

[Ricardo Bevilacqua]

I was installing a boot splash when i got this message

//////////////////////

Inside /boot/grub I have much less than 1Mb.

Since the boot partition has 40Mb, why does my system say that is full

I would hazard the guess, that your boot is full because the journal uses 32mb 
for itself.

There is NO reason to use ANY journaling fs for /boot.

You can try two things: make journal smaller (I don't know how) or change boot 
to ext2 (good choice).

I really love reiserfs, but it is the wrong fs for /boot. like ext3 is the 
wrong fs for /boot. Or Xfs. or jfs.

I agree with you, actually, I can't figure out any good reason for
using journaling file system for /boot.

But, just in case, I'm going to investigate a little bit more.

I don't think that you need to investigate more. Just be carefull when nuking 
the fs - you have to setup grub after that again. It might be smart to save 
the configs in /boot/grub ;)

Make a back up:

# mount /boot
# cd /boot
# tar cpvf /tmp/boot_backup.tar . 

Then mkfs <type> on your /boot partition, re-install grub and untar the /boot 
archive and cp -a <kernel_files, grub.conf, etc.> from /tmp to /boot as 
needed.

HTH.

There's no need to translate it.  When posting output of a command, 
preceding the command with LC_ALL=C will undo any localisation.  In 
this case: 'LC_ALL=C  df -T /boot' should produce unlocalised text.

Try using:
du -xa /boot | sort -rn
as root to locate the space hogs, which may be hidden files.  (du does "lie" 
sometimes though, because the assumptions it makes about file size aren't 
always true.)

You might also fire up filelight and/or the file size view of konqueror 
(either would also need to be as root) if you prefer a graphical view.  (They 
will suffer from the same limitations as du, but their assumptions my be 
different.)

Oh, I'm not sure while filesystem you are using, but reiserfs reserves some 
space for the block usage bitmap and misc. metadata, and that takes up a 
number of MB.

Almost the same with a graphical view.

You might be right, but still, we have found out that the files are
~15Mb, if the partition has a size of 40Mb, is it possible that
reiserfs is using almost 25Mb for storing data?

it is using per default 32mb for its journal.

The missing mb (32+15>40) comes from two facts:
du lies
and tail packing.

Actually I think he misread the output of du.  It should be ~7283
for /boot at the "root" level.  Don't add the individual
subdirectories/files coz you're just counting everything twice.  Add
8193*4096 bytes for the reiserfs journal and you've got 40055 (~40G).

Don't use ext3 for /boot - there's just no need for a journal on
/boot, as you'll VERY rarely write to it. For boot, the journal
is just a waste - a waste of 32m, to be exact. Combined with
your ~7Mb, this gives 40m.

I was wrong. ext3 does not use 32m for journal on such a small
filesystem.

Well, finally, the trouble was the file system.
Now I have changed it from reiserfs to ext2. No troubles at all, as you said.

Thanks for helping me with this newbie mistake =)
