Dear Junjiro,
after a _long_ time with absolutely no issues using an old but stable SuSE
9.3 diskless setup with aufs, new hardware forces me to use newer kernels
(and a newer distribution in the end).
But at this point, I need to adapt a more current kernel to the old setup.
Stable setup: kernel 2.6.11.4 with aufs 20070327
New setup: kernel 2.6.27.39 with aufs2-standalone-27-20100111
The new kernel is from openSUSE 11.1, with (only) aufs2-base.patch and
aufs2-standalone.patch applied, and the usual :( distro fallout fixed..
The root filesystem is assembled from initrd:
if [ "$rootfstype" = "nfs" ]; then
base=$(basename $rootdev)
rwroot=${rootdev%%$base}hosts/$base/$HOSTNAME
if [ -n "$aufsmnt" ]; then
insmod $aufs_module
nfsmount -oro,intr $rootdev /roroot || die 1
nfsmount -orw,intr $rwroot /rwroot || die 1
mount -t aufs -o dirs=/rwroot=rw:/roroot=nfsro none /root || die 1
else
echo "Mounting root $rootdev"
nfsmount $opt $rootdev /root || die 1
fi
fi
for aufs2, I tried these mount variants:
mount -t aufs -o br:/rwroot=rw:/roroot=ro none /root
resulted in:
aufs au_xino_create:659:mount[206]: xino doesn't support
/tmp/.aufs.xino(rootfs)
mount -t aufs -o br:/rwroot=rw:/roroot=ro,xino=/rwroot/.aufs.xino none
/root
resulted in:
aufs au_xino_create:659:mount[206]: xino doesn't support
/rwroot/.aufs.xino(nfs)
mount -t aufs -o br:/rwroot=rw:/roroot=ro,noxino none /root
resulted in:
aufs au_opts_mount:1456:mount[206]: no branches
So far, I'm unable to use aufs2 in my setup, which is a real pity.
Given, that tmpfs seems to be unable to carry the xino file, and so does
nfs, how is a NFS3 diskless setup supposed to work now?
Do you have any ideas or recommendations on how to precede?
Thanks,
Pete
