Hello. I switched /dev/hda4 / from ext3 to reiserfs with blocksize 1024.
But after rebooting yaboot says
Code:
unsupported journal size, not a power of 2:8125
hd:4,/boot/kernel: unknown or corrupt filesystem

I looked into the forums, and they say, that it's possible to boot from reiser without /boot ext2.
fsck.reiserfs and chroot are working fine on /dev/hda4. The kernel has reiserfs included, but it just doesn't load. Yaboot seems not to know reiserfs?

This is links2 via universal-cd.

Yaboot definitely can boot reiserfs otherwise I would be in trouble.
Someone more knowledgable will have to review your error message. From the output of dmesg on my
computer the "journal size" is 8192 so there may be some problem with the partition info or with some
kernel parameter.

Hello fb, thanks for your support.
I figured out that other blocksizes than the default 4096 are not able to boot. Not sure if that is ppc specific.
I'm back with a booting reiserfs with a really faster portage.

I took b=1024 because of the very small ccache tree. All of the file have to be 4k now.
As I understand, mounting reiserfs as default would take such files directly into the tree. But mounting with notail (as I've read would bring performance) takes full blocksize for each file? Anyone knows more in detail?

I think the statement that with notail you take full block size for a small file or the small tail of
a file just over a multiple of 4K size, is correct. I am not sure about the performance aspect. One
of the main point of the notail option is that some program like lilo (not really a concern on ppc)
cannot work properly without it.
From the mount man-page:
Code:
notail By  default,  reiserfs  stores small files and `file tails' directly into its tree. This
      confuses some utilities such as LILO(8).  This option is  used  to  disable  packing  of
      files into the tree.
