[gentoo-dev] Gentoo perffered File system

[Shanon Loveridge]

I was wondering now that it doesn't look like XFS is
the preffered filesystem to gentoo (Not in gentoo
sources and it doesn't look like it will go into the
standard kernel) what is the preffered / recommended
filesystem for gentoo?

Thanks

I use XFS because I like acls and feel not confortable with ext3 + acl patch
(maybe I'm wrong). XFS works well. (there are a couple of glitches in 
reporting errors
"preserving permissions", but probably it will be the same with ext[23] 
acl).
I use "2.4.18-xfs".

There's no thing like Gentoo "default" kernel. You must
choose the kernel during installation.
The so called "gentoo" kernel is a pached and powered kernel, choosen to
offer more features than vanilla kernel, but not required in order to 
execute the
Gentoo distribution.

  Unfortunally, the preemptive kernel patch conflicts with current 
version of XFS,
and may cause data curruption. I don't know if just disabling the 
complile-time
option in the gentoo-patched kernel will allow xfs to run (I wouln't try 
it out on
a production machine :-). You will probably have to use the xfs-sources 
kernel, but
you will not have all the goodies a gentoo-patched kernel will have, but
it works well.

  The issues of the gentoo kernels are identical thoughout the linux 
community
because the kernel *is* Linux and it's identical in all linux 
distribution. Gentoo
gives you more freedom in choosing the kernel, and the filesystem.

Look at the kernel ebuild files in /usr/portage/sys-kernel/*
in some ebuilds you will see the list of patches that will be applied to 
that kernel.

What filesystem do you like more?

Does anyone use ext3 + acl ?
Does anyone depend on the goodies in gentoo-kernel (vfat symlinks, EVMS,
preemptive kernel....), in production systems ?

Marko

XFS is in gentoo-sources-r7 and works like a charm, as long as you do not turn 
on kernel preemtion.

Actually, I'm running XFS with kernel preemption on two machines and
neither has given me any problems.  Of course YMMV, don't use it on
critical systems, yadda, yadda.

  personally I use reiserfs and ext3.  but by these days I don't
  really see any major problems with any of the big three journaling
  filesystems under linux.

  I have had more filesystem-related problems with ext3 than with
  reiserfs though.  for some odd reason.  :-/

You might do wise in checking the newer acl tools and xfs patches. The work 
is ongoing.
Is this a 2.4.18-xfs from CVS or the split patches?

We just released the 2.4.19 split patches although there are some small 
problems cropping up that might prove to be wiser to get CVS (which has a 
fix merged).

AFAIK that bug got fixed some time ago in 2.4.18 although it is not 
"supported". Another option would be checking out the 2.4.19-aa tree which 
has some VM fixes/tuneups etc.
