Amazon S3 not sync for ReadyNAS home directories
I have a ReadyNAS 2304 that has been syncing a share to an Amazon S3 bucket for a few years. This has worked well. I recently configured a second session on the ReadyNAS to sync the user home directories to a second directory in the same S3 bucket. The behavior is interesting in that it is only synching two of the user home directories, and not the remaining five. No related errors that I can see in the log files. I am using the most current firmware (6.10.10 - previously was using/tried on 6.10.8). I've ripped out the session and recreated. I've tried synching both /home and /data/home (/home is just a softlink to /data/home). The only other thing that I can think of is that it is possible that I had created a some of the home directories manually / they may not have been created by the frontend webpage. The permissions appear to be the same on all of the home directories, at least, the home directories themselves.
Home "directories" are actually BTRFS sub-volumes if properly created by the OS. They are only created automatically after the first time the user logs in. So if you created a user and then, not finding the home directories, manually created them as standard directories, that could be the issue. Once you created them, the OS could no longer create the sub-volumes because there would be a name conflict.
There is a command available via SSH to force creation of home directories, it's mkhomedir_helper.
See if btrft subvolume list /home shows them as subvolumes. If it doesn't, you can move the incorrectly created directories elsewhere, properly create hem, and then copy the contents of the old ones to the new ones.

Did you check the ACL?
How did you create them?

Ahh, thank you for the information! Using the btrfs command I was able to determine that the only two home directories that were syncing were the two that I must have manually created. The ones that were created properly / by the system / with mkhomedir were the ones that were not syncing.
I found that I can solve the syncing problem by manually creating a syncing session for each home directory itself (/data/home/userxx) instead of the broader /data/home).One more question. I see in each home directory (including the ones that I manually created), the system creates an .ssh folder with an empty ssh_authorized_keys file, perhaps to keep users from logging in via ssh. I have been unable to delete this file which is preventing me from deleting the two manually created home directories (even after renaming them). As root I should have permissions and using getfacl I don't see a reason why I shouldn't be able to. If trying to do via the command line, I get an error 'rm: cannot remove 'ssh_authorized_keys': Operation not permitted'. If I delete via the web front end it just silently fails.
