Hi,

For Gentoo you can find an ebuild for aufs now on the sunrise overlay :)

Re: aufs on a 2.4 kernel ?

2007-02-14 Thread sfjro

Flemming Madsen:
 Is anybody by any chance contemplating a backport of aufs to the 2.4 kernel.
 Would be much appreciated for use in embedded systems.

Unfortunately, I don't have such machine and disk space.
If anybody start backporting, I will try answering the questions.
I forgot many things in 2.4 since it was years ago when I touched it
last time.
I guess it is possible to backport aufs if all the features are not
necessary. i.e. the limited or basic features only.

Re: aufs max branches

2007-02-14 Thread Tomas M
 Please simply ignore this, I was talking about two different things at 
 once. The problem can be reproduced only during LiveCD startup, using 
 busybox command with 'aufs' parameter.

ergh. I was trying to say:

The problem can be reproduced only during LiveCD startup, using
busybox's mount command withOUT 'aufs' parameter.

builtin aufs in kernel

2007-02-14 Thread Fernando A. P. Gomes
Hi, 

 I try to compile aufs with CONFIG_AUFS = y, but nothing happens in my kernel 
source tree. 
 It's possible compile aufs builtin in the kernel, without modules?

Regards,
Fernando Gomes

NFS branch is not supported on 2.6.15.7

2007-02-14 Thread Peter Kruse
Hello List!

I just wanted to start using aufs but mounting an nfs branch
failed with kernel 2.6.15.7 and aufs 20070212.
So I modified fs/aufs/branch.h with this patch:

--- branch.h.orig   2007-02-14 16:03:04.0 +0100
+++ branch.h2007-02-14 10:15:34.0 +0100
@@ -87,7 +87,7 @@
  /* 
-- */

  #define _AufsNoNfsBranchMsg NFS branch is not supported
-#if LINUX_VERSION_CODE == KERNEL_VERSION(2,6,15)
+#if LINUX_VERSION_CODE == KERNEL_VERSION(2,6,14)
  #define AufsNoNfsBranch
  #define AufsNoNfsBranchMsg _AufsNoNfsBranchMsg
  #elif LINUX_VERSION_CODE = KERNEL_VERSION(2,6,19) \

Then I did on a diskless client where /usr is mounted on /dev/rd/0:

mount -t aufs -o br:/usr=rw:/apps/master/usr=ro aufsroot /usr

where /apps/master is an nfs mounted copy of an installed server.
It looks like it works except:

# find /usr  /dev/null
find: WARNING: Hard link count is wrong for usr/lib: this may be a bug 
in your filesystem driver.  Automatically turning on find's -noleaf 
option.  Earlier results may have failed to include directories that 
should have been searched.

But I'm not sure if this warning can cause serious problems.
Why is it that on 2.6.15 NFS branch is not supported, what
test should I run to see if this problems exists on 2.6.15.7?

Cheers,

Peter
