PAGESIZE and btrfs
Hello!
So, I managed to compile a new kernel and start it.
I have a Debian system running and chrooted into a Gentoo system and
compiled a gentoo kernel, one with 4k pagesize and one with 64k
pagesize. The reason is that the nouveau driver is said to only work
with 4k pagesize, but the standard Debian kernel for ppc64 uses 64k
pagesize.
No I have hit another issue:
http://comments.gmane.org/gmane.comp.file-systems.btrfs/16583
I use btrfs for the benefit of being able to return to previous
snapshots, so would be able to reset a system to a working state, be it
Debian (from a booted Gentoo as a resuce system) or Gentoo (from a
booted Debian as a rescue system).
No I am able to boot into Debian and into Gentoo: but ONLY with a 64k
pagesize kernel!
The 4k pagesize Gentoo kernel tells me that btrfs cannot be mounted,
because of an unsupported sector size of 65536.
This is a bad situation.
Should I do it all over again on an ext4 file system?!?!?
I would rather like the nouveau driver to be fixed to work on a 64k
pagesize system (or the btrfs driver to work on both 64k and 4k equally).
I hat it when things like this happen…
