The brilliant plan to create a Raspberry Pi NAS isn't so brilliant after all. OK, I got the permissions issue sorted- for some reason which I am completely unable to fathom, permissions for files in the /media/drive1/adam directory were assigned to ilana instead. No clue why- adam owned the directory, etc. I sorted that by first deleting all accounts- linux and samba- then recreated my account 100% before adding my wife's.
Now, the problem could be more troublesome: copying files from /media/drive1 to /media/drive2, whether with rsync or simple cp -r, is killing the mount. The xcopy/cp job runs for 1 min. or so, and then dies, with broken pipe errors galore. After the xcopy/cp crashes, the mount it self is hosed- still mounted, but unusable (i/o error when you try to ls). I need to first umount and then mount -a to try again.
Here, FWIW, is the response when I run rsync manually (as opposd to as a cron job):
root@raspberrypi:~# sudo rsync -av --delete /media/drive1/adam /media/drive2/adam --timeout=10
