Full Discussion: Why does ext3 allocate 8 blocks for files that are few bytes long
Operating Systems Linux Why does ext3 allocate 8 blocks for files that are few bytes long Post 302322842 by Corona688 on Thursday 4th of June 2009 04:51:21 PM

Hmm. Tail-packing is being worked on for ext3 apparently but still an alpha feature.

I do think you can get that extra space if you really need it. But if your filesystem gets to the 99% full point where it needs it then you've got bigger problems. No filesystems deal well with being nearly full.

extlinux

extlinux(1)						      General Commands Manual						       extlinux(1)

NAME

       extlinux - install the SYSLINUX bootloader on a ext2/ext3 filesystem

SYNOPSIS

       extlinux [options] directory

DESCRIPTION

       EXTLINUX is a new syslinux derivative, which boots from a Linux ext2/ext3 filesystem.  It works the same way as SYSLINUX, with a few slight
       modifications.  It is intended to simplify first-time installation of Linux, and for creation of  rescue  and  other  special-purpose  boot
       disks.

       The  installer is designed to be run on a mounted directory.  For example, if you have an ext2 or ext3 usb key mounted on /mnt, you can run
       the following command:

	      extlinux --install /mnt

OPTIONS

       -H, --heads=#
	      Force the number of heads.

       -i, --install
	      Install over the current bootsector.

       -O, --clear-once
	      Clear the boot-once command.

       -o, --once=command
	      Execute a command once upon boot.

       -r, --raid
	      Fall back to the next device on boot failure.

       --reset-adv
	      Reset auxiliary data.

       -S, --sectors=#
	      Force the number of sectors per track.

       -U, --update
	      Updates a previous EXTLINUX installation.

       -z, --zip
	      Force zipdrive geometry (-H 64 -S 32).

BUGS

       I would appreciate hearing of any problems you have with SYSLINUX.  I would also like to hear from you if you have successfully	used  SYS-
       LINUX, especially if you are using it for a distribution.

       If  you	are reporting problems, please include all possible information about your system and your BIOS; the vast majority of all problems
       reported turn out to be BIOS or hardware bugs, and I need as much information as possible in order to diagnose the problems.

       There is a mailing list for discussion among SYSLINUX users and for announcements of new and test versions. To  join,  send  a  message	to
       majordomo@linux.kernel.org with the line:
