X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 13 Jul 2009 04:10:09 -0000 Hello all, I'm about to build a new file server using 3ware 9690SA-8E controller and 4x Western Digital RE4-GP 2TB drives in RAID6. It is likely to grow in the future up to 10TB. I may use FreeBSD 8 on this one, since the release will likely be made by the time this server goes into production. The question is a simple one - I have no experience with ZFS and so wanted to ask for recommendations of that versus UFS2. How stable is the implementation and does it offer any benefits in my setup (described below)? All of the RAID6 space will only be used for file storage, accessible by network using NFS and SMB. It may be split into separate partitions, but most likely the entire array will be one giant storage area that is expanded every time another hard drive is added. The OS and all installed apps will be on a separate software RAID1 array. Given that security is more important than performance, what would be your recommended setup and why? - Max
