RE: FreeBSD equivalent of Microsoft DFS
for all: MS DFS = MS Distributed File system is NOT a FS it's a shared directory on a drive that is replicated via AD mechanism to 1 or more locatations If setup correctly DFS can have 2 or many more servers, and to replicate it only needs a partner server to replicate with. all other servers can be turned off .. its neither a ring or a star shaped network. (not 100% true but makes explaining a lot easier) In Freebsd that woud be a CIFS or NFS share that is synced over 1 or more sites (without bandwith control ) The only issue if you want to replicate this within Freebsd is how to setup the sync process for more then 3 hosts. And more specific if 1 file gets edited on to seperate "servers" and replicated to a 3rd server, what happens then? Of course such a write action "when it happens" is very very small chance. IF you want to use FreeBSD as a file server for a windows enviroment (with ZFS) you can do 2 things 1) use ZFS and make a ISCSI -disk (istgt port for now) and connect the ISCSI disk to a Virtual server with a windows "server" host 2) use ZFS + SAMBA, configure samba to use the AD information to give access (Single Sign On) The first one is the easiest & fastest way however it will cost you performance compared with the second solution. The most difficult is to have samba connecting to a AD enviroment without any alterations on the windows machines/ad and kerberos. However SAMBA & AD are reported to have a love hate relation ship working together, and can break > Date: Mon, 9 Aug 2010 15:42:59 -0700 > From: edfle...@gmail.com > To: freebsd-questions@freebsd.org > Subject: FreeBSD equivalent of Microsoft DFS > > Is there a FreeBSD equivalent to Microsoft DFS, i.e., software that > will replicate delta level file changes of network shares among > multiple servers in real time? > > Would that be rsync with just a frequently scheduled cron task? > > Thank you, > Ed > ___ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

It's not 'real time' but you can achieve something like this by using a combination of ZFS snapshots and ZFS send / receive. > Would that be rsync with just a frequently scheduled cron task? Which works very well indeed in many situations. Someone else has already mentioned distributed filesystems line AFS -- another thing to contemplate is the new HAST capability in FreeBSD: http://wiki.freebsd.org/HAST It's conceptually similar to Linux DRBD, which in theory you can use under FreeBSD as well, but no idea how it performs.

A distributed filesystem like Coda[1] or Andrew FS[2][3] would be better. Not sure about there FreeBSD support.

FreeBSD equivalent of Microsoft DFS
Is there a FreeBSD equivalent to Microsoft DFS, i.e., software that will replicate delta level file changes of network shares among multiple servers in real time? Would that be rsync with just a frequently scheduled cron task?
