[Samba] Shared Samba locking system
Hi all, I'm wondering whether it would be feasible to share the Samba lock file between two Samba servers. My implementation will be similar to this: I have two sites each with its own OpenBSD 3.8 Samba Server connected via OpenVPN over a not-so-good link. Ultimately, the link isn't too bad however the users are often calling on large file and crashing Mircrosoft Programs as they're not designed to wait that long. My plan is to run rsync between the two servers (in both directions) to synchronise the data. This will probably be done on a 5 minute basis, or maybe 15. My issue from here is that when file foo is opened on Server A, there will be no lock in place on Server B to prevent simultaneous editing. Obviously, the effect of this is that I have two versions of the same file and rsync will simply blow one away with the newer one, despite the older one possibly having new data. My intention was to share the Samba lock file live across the VPN using maybe NFS or some other means. I've been reading up on the locking system of Samba in an attempt to ascertain the ability to do this but would like to open it to you guys for advice. Alternatively, if there is another option that people can suggest for doing what I need I'm open for suggestions. Kind regards and thank you in advance, Sh4d03 -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba

The locking databases need full POSIX mmap and fcntl semantics and don't work so well even on distributed filesystems using gigabit. Using a not-so-good link isn't possible :-). I'd look into replicating the actual data files via rsync if you must share stuff between the two sites.
