I noticed that you may be misunderstanding what I wrote. It may depends upon the fuse version, kernel version or something else. If you try fusexmp or another fuse and it succeeds, then you can check the difference between the one and the posixovl.

It tests the existence of the specified dir.
As you know, the link count of a removed dir (or file) is 0.
Aufs lookups and gets the inode, and then add it to aufs. During this
operation, aufs does not hold any lock. So someone else may remove the
dir.

I executed stat after the attempt to mount aufs.
Would you please explain briefly what does the code chcek for?
I'll resend it to the developer of posixovl.
// from branch.c, lines 377-380
if (unlikely(!inode->i_nlink)) {
Err("no existence %s\n", add->path);
goto out;
}
Thank you very much.

Re: bug in kernel 2.6.22 with removing branches

I tried adding a branch which is mounted by FUSE_CVS/fuse/example/fusexmp.c, and succeeded. If you try fusexmp and it succeeds, then the posixovl should be fixed. Just a guess, executing 'stat /mnt' before mounting aufs may affect the result.

mount aufs test_add
Hello, my setup is following: mount -t vfat /dev/sda1 /mnt/ # to mount vfat on /mnt/ mount.posixovl /mnt/ # to overmount vfat in order to support links mount -t aufs -o br:/mnt=rw aufs /union Aufs reports aufs test_add:378:busybox[2922]: no existence /mnt As I can read aufs/branch.c, line 377, there is a test if inode->i_nlink ... nevertheless 'stat /mnt' outputs Links: 4. I have no idea if this information is relevant though :) Should the posixovl filesystem be fixed, or should aufs be fixed? Posixovl is a FUSE-based filesystem, source can be found here: https://dev.computergmbh.de/svn/posixovl/trunk/ Thank you very much for answer.
