I'm trying to setup an aufs branch that consists of another aufs branch and a davfs mount. I'm using the latest CVS checkout (20090126), so I realize I'm in unsupported territory, but I'm wondering if anyone has gotten this to work. I can get it almost working, but I get corrupted directory listings and inaccessible files.
Here's my system setup: * OS. 2.6.22.9 * Config: attached * Mounts: rootfs / rootfs rw 0 0 /dev/root.old / ext2 rw 0 0 /proc /proc proc rw 0 0 /sys /sys sysfs rw 0 0 /dev/hdc /cdrom iso9660 ro 0 0 /dev/cloop /KNOPPIX iso9660 ro 0 0 /ramdisk /ramdisk tmpfs rw 0 0 /UNIONFS /UNIONFS aufs rw,si=f78e2480,xino=/ramdisk/.aufs.xino,br:/ramdisk=rw:/KNOPPIX=rr 0 0 tmpfs /UNIONFS/lib/init/rw tmpfs rw,nosuid 0 0 usbfs /proc/bus/usb usbfs rw,nosuid,nodev,noexec 0 0 /dev/root.old /dev/.static/dev ext2 rw 0 0 tmpfs /dev tmpfs rw 0 0 tmpfs /dev/shm tmpfs rw,nosuid,nodev,noexec 0 0 devpts /dev/pts devpts rw,nosuid,noexec 0 0 fusectl /sys/fs/fuse/connections fusectl rw 0 0 /dev/shm /dev/shm tmpfs rw,nosuid,nodev,noexec 0 0 rpc_pipefs /UNIONFS/var/lib/nfs/rpc_pipefs rpc_pipefs rw 0 0 http://bccd-ng.cluster.earlham.edu/svn/bccd-ng/trunk/trees/software/bccd/software/ /mnt/bccd coda rw,nosuid,nodev 0 0 none /UNIONFS/bccd/software.local aufs rw,si=f60c8e80,xino=/UNIONFS/bccd/software.local/.aufs.xino,br:/UNIONFS/bccd/software.local=rw:/mnt/bccd=ro 0 0 I'm using /UNIONFS/bccd/software as my read/write branch, /mnt/bccd as my read-only branch, and /UNIONFS/bccd/software.local as the mount point for aufs. When I run "ls -l" on the mount, I get output like this: ls: cannot access /UNIONFS/bccd/software.local/PSC_DX: Operation not permitted ?????????? ? ? ? ? ? PSC_DX Running "ls -l" on the branches returns properly: $ ls -l /mnt/bccd/ -rwxr-xr-x 1 root root 22 Dec 16 23:28 PSC_DX $ ls -l /UNIONFS/bccd/software.local/ lrwxrwxrwx 1 root root 16 Apr 16 22:29 PSC_DX -> PSC_DX-04.3.3000 Has anyone got this working, or can confirm that this is completely unworkable? Is branch-within-a-branch support going to be coming back with the new git aufs? Thanks, -- -- Skylar Thompson ([email protected]) -- http://www.cs.earlham.edu/~skylar/
