 Posted: Wed Apr 23, 2008 12:09 pm Post subject: Grub and newly made ext3 partitions |
 |
|
I was moving my installation to a new, larger harddisk, and had
problems getting grub to recognize my /boot partition. Googling the
error message, I saw that others had solved the same problem by
changing from ext3 filesystem to reiserfs, it also worked for me.
On my old disk, /boot was ext3, so why did it stop working? I have
noticed that mke2fs is making much fewer superblocks etc than it used
to do, it looks like the default parameters have been changed to be
more suitable for large disks. Could these new parameters be breaking
grub?
Here are some recent changes to /etc/mke2fs.conf

I would suggest using ext2 for a boot partition.

Yes, that makes sense. But I doubt it changes anything significant, presumably grub just treats ext3 as ext2 and ignores the journal. |
