Unfortunately I don't understand what your situation is. How did you create the file? Bypasseing aufs? Or do you expect the internal copyup in aufs? If you are saying, - /your/aufs = /gluster-rw + /local-ro - /local-ro/dirA/fileA exists - the owner of /local-ro/dirA is not root. - /gluster-rw/dirA and /gluster-rw/dirA/fileA don't exist - echo >> /your/aufs/dirA/fileA - the owner of /your/aufs/dirA becomes root unexpectedly, that it the problem. Then I'd ask you to test "mkdir /gluster-rw/dirB" and see its owner. And give me these info. (from the aufs README) ---------------------------------------------------------------------- When you have any problems or strange behaviour in aufs, please let me know with: - /proc/mounts (instead of the output of mount(8)) - /sys/module/aufs/* - /sys/fs/aufs/* (if you have them) - /debug/aufs/* (if you have them) - linux kernel version if your kernel is not plain, for example modified by distributor, the url where i can download its source is necessary too. - aufs version which was printed at loading the module or booting the system, instead of the date you downloaded. - configuration (define/undefine CONFIG_AUFS_xxx) - kernel configuration or /proc/config.gz (if you have it) - behaviour which you think to be incorrect - actual operation, reproducible one is better - mailto: aufs-users at lists.sourceforge.net ---------------------------------------------------------------------- J.
