Let me make sure.
- /local-ro/dirA exists and its owner is aufstest.
- /gluster-rw/dirA did not exist.
- /gluster-rw/dirA is created by aufs internal copyup, and its owner is
incorrect.
Right?

Does it mean /local-ro exists on /dev/sda1?

Waoh, that is very old, more than a year ago.

This seems to be your first problem.
As long as you use FUSE as aufs branch fs, you should enable
CONFIG_AUFS_WORKAROUND_FUSE.
Also I'd suggest you to enable CONFIG_AUFS_HINOTIFY too, if you have a
plan to modify /local-ro or /gluster-rw directly (bypassing aufs).
I hope CONFIG_AUFS_WORKAROUND_FUSE help you.
But I am not sure it will solve the problem prefectly because I am
forgetting such old version...
