reiserfs boot partition full [solved]

I just tried to upgrade my kernel using genkernel. Everything went fine, until it tried to copy the kernel image to /boot, where it failed, saying the device was full. I have /boot on its own partition with about 40MB. df says it is 96% full with 38 MB used. However, du says that there is only 5.4 MB used. I ran reiserfsck (for it is a reiserfs partition), and it found no problems. Any ideas on what I can do to get that space useable again?

reiserfs has to use 32MB for its journal. So you only have about 8Megs for the kernel. Don't use reiser for /boot, use ext2.

I'm sorry but I have to ask the dumb question first. Did you mount /boot ?

umm, if /boot wasn't mounted then he would have plenty of space as it would just be on the main partition. :roll:

edit: oh, by the way, we have same post count. :lol:

Ya, your right. For some reason I was thinking of /boot as a pointer not a directory, which it is.

Still you could try using dd to move the data over, reformat the partition and try again...

Then, before I screw everything up, can someone confirm that this should work.... any additional suggestions would be nice.

1) tar up /boot
# tar cf /somewhere/boot.tar /boot
2) reformat with ext2
# mke2fs /dev/sda1
3) restore directory structure
# cd /boot
# tar xf /somewhere/boot.tar

You will need to change your fstab from reiserfs to ext2 or it will not boot properly

I successfully converted /boot to ext2, and go the machine to reboot (after figuring out that "notail" is a reiserfs mount option and had to be removed), now I'm having problems with grub and my new kernel, if I can't figure that one out soon, I'll start a new thread. Thanks for help everyone!
