Disk space dissepeared

Hi there
I've got a strange problem here : my boot partition is full but there is actually almost nothing in it.

Code:

$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda8              14G  2.1G   12G  16% /
none                  506M     0  506M   0% /dev/shm
/dev/sda5              23G   15G  7.5G  67% /mnt/dts
/dev/sda6              23G   22G  536M  98% /mnt/dte
/dev/sda7              47M   42M  5.7M  88% /boot

$ du -h /boot
309K    /boot/grub
9.3M    /boot

$ ls -lah
total 9.0M

-rw-r--r--  1 root root 1.7M 2006-08-07 02:34 vmlinuz26

I've investigated but I can't find the source of the problem so any kind of help would be appreciated.

Thanks,
Rognon

What fs are you using for /boot? A journaling fs (ext3/reiser) will eat 32MB (by default) for the journal.

I'm using reiserfs... I've always used a 50mb ext3 partition for /boot but never had this problem. I tried reiser the last time I switched distro.
What would be the best way to change fs without formating ? Would copying all the files elsewhere, formating then putting the files back work ?

Yeah, that should work fine, nothing in /boot is required while the system is running. Remember to update /etc/fstab before you reboot (though it's no big deal if you forget, /boot isn't really used after the kernel is loaded).

It's usually best to use ext2 for /boot as it's so small. Since you only write to it when installing a new kernel, fs corruption is a minor issue, so journaling isn't really required.

It works perfectly. I had to reinstall grub but now it works. Thanks
