Re: pmfsrr mode
Jean-Ray Arseneau: I have included linked to the files. They are: Ok thanx. The log shows the expected behaviour, but the result is wrong. To investigate more, would you apply this debug print patch and try again? This patch doesn't solve the problem, but help investigating. Original J.

Adding verbose (and/or -v) doesn't print anything that I could find, do I need another option for verbose? or where should it be printed? If CONFIG_AUFS_XATTR is disabled, then XATTR/ACL is not the problem. I'd ask you to enable CONFIG_AUFS_DEBUG and run # echo 1 /sys/module/aufs/parameter/debug mv -v $tmp/union/a/{b,c} # echo 0 /sys/module/aufs/parameter/debug I've enabled debug (for the mount as well). For good measure, I'm attaching all the relevant data (including dmesg output). The kernel is 3.19.3 with the patch you sent, and the only aufs mounted is the one after running the script (when not unmounting it). In the coming week, I probably won't have much time to check this further.

Yair Yarom: CONFIG_AUFS_XATTR is enabled. Adding verbose (and/or -v) doesn't print anything that I could find, do I need another option for verbose? or where should it be printed? It the system logfile with the priority kern.err. I've enabled debug (for the mount as well). For good measure, I'm attaching all the relevant data (including dmesg output). The kernel is 3.19.3 with the patch you sent, and the only aufs mounted is the one after running the script (when not unmounting it). Your case looks different a little bit from Christoph Pleger's, but it must be same essentially. I've found linux NFS client always sets MS_POSIXACL (which is a flag in VFS layer) even if it was mounted with 'noacl.' I don't think it illegal or violation something, but it surely makes aufs (and me) confused. I may need some dirty workaround, but I'll consider more and more. When I found a solution, I'll send you a patch and ask a test. J. R.
