Hi Junjiro, I'm experiencing some problems with current releases of aufs2 with xfs layers:
$ mount -t aufs -o br:/work/01rw=rw:/work/01ro=ro aufs /work/01 Apr 24 01:07:32 tyrex kernel: [ 151.965865] aufs 2-standalone.tree-33-20100412 Apr 24 01:07:51 tyrex kernel: [ 170.745345] aufs test_add:248:mount[7044]: uid/gid/perm /work/01ro 1000/2222/0770, 0/2222/0770 Apr 24 01:07:51 tyrex kernel: [ 170.745405] aufs au_xino_create:659:mount[7044]: xino doesn't support /tmp/.aufs.xino(xfs) Hmm, /tmp is xfs $ mount -t tmpfs -o size=200M tmpfs /var/tmp/.xino $ mount -t aufs -o br:/work/01rw=rw:/work/01ro=ro,xino=/var/tmp/.xino aufs /work/01 Apr 24 01:09:05 tyrex kernel: [ 244.383688] aufs au_xino_create:631:mount[7073]: open /var/tmp/.xino(-17) This is with kernel 2.6.33.2 with aufs2-20100412 and 2.6.34-rc5 with aufs2-20100419, default compilation (no option tweaking). All packages are available here (for openSUSE 11.1): http://download.opensuse.org/repositories/home:/frispete:/kernel-2.6.33/ http://download.opensuse.org/repositories/home:/frispete:/kernel-head/ I had these aufs mounts working with earlier kernels for sure.. Any idea, Pete ------------------------------------------------------------------------------
