I've been running a 1.3TB zfs/raid-z on a core 2 duo for a while and I never had to do any tuning the other i386 people have mentioned. The only problem I ran into was not being able to directly samba share out the zfs. I got around it by using a local nfs loopback and samba sharing the nfs mount point. Read speeds are acceptable for a media storage server, but the write speeds are horrendous. Trying to write via samba was about 1GB per hour. On my Windows box I installed Microsoft's Services For Unix and mounted the NFS shares directly. I ran into some interesting behaviour but I don't know if I should blame Windows or FreeBSD. I could only mount one NFS share per reboot, and after a reboot the one I had mounted before would disconnect and refuse to reconnect. The only reason I can't say for certain it was a Windows problem is FreeBSD started showing the TCP segment rejected errors others have reported on this list. Once I did get a successful mount if I just tried directly copying to the idle server I would get around 1MB/s (yes Byte, not bit) which was still too low for me. Strangely, I found if I created a looping script that did an ls every second on the zfs from an account on the FreeBSD box itself my NFS write speeds would jump up to a stable 8MB/s which was pretty respectable. Strange behavior, but it worked. So basically, I haven't lost any data with ZFS, and it seems very good for local usage. But I have run into some speed problems when trying to get it to play nice with a Windows machine. -- Brian Donnell On 6/20/07, Olivier Mueller <om-lists-bsd@omx.ch> wrote: > > Hello, > > I have to setup a file storage server (non-critcal, just as secondary > backup server) and I am wondering if would be a realistic idea to start > using ZFS.
