anyone using ZFS for real?

I'm using it for everything (including root) on several systems: 1 amd64 machine in a desktop role * single SATA disk 1 i386 machine in a server role (with only 512MB RAM) * raidz over 3 ATA100 disks 4 i386 machines in desktop roles * two are single disk setups * one is a 3 disk raidz (SATA) * one is a 1GB compactflash card in a PCMCIA converter (diskless laptop) 1 bootable USB flash memory stick (i386 kernel) that I sometimes plug in to random machines. It's a 2GB stick and is configured with lots of desktop stuff but is also handy for hardware tests and recovering stuff off broken windows machines. gzip compression really shines here I also have a couple of external USB hard drives that have a zpool on them. One of them is geli encrypted. The other holds the src/obj/ports filesystems for my flash-based systems, so it gets plugged in and zpool import/export'd a lot when there are updates. My recipe generally involves setting vm.kmem_size to somewhere between 1/3 and 1/2 of physical RAM size, and reducing kern.maxvnodes to somewhere between 1/2 and 2/3 of its autotuned value. I sometimes disable prefetch, but honestly I can't tell a difference between it being on or off.

I recall that amd64 and at least 1GB of RAM were recommended. http://lists.freebsd.org/pipermail/freebsd-current/2007-June/073972.html Nikos ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: anyone using ZFS for real?
I've been using it just for the /usr/ports on my i386 laptop for a while (dual core T2300 @ 1.66GHz with 1 gig Ram:) ([EMAIL PROTECTED])$sudo zpool history tank History for 'tank': 2007-04-11.10:45:56 zpool create tank ad0s4a 2007-04-11.10:46:35 zfs create tank/ports 2007-04-11.10:47:06 zfs set compression=gzip tank/ports 2007-04-11.10:53:29 zfs set mountpoint=/usr/ports tank/ports 2007-05-11.09:31:37 zpool scrub tank 2007-08-08.12:31:44 zpool scrub tank 2007-08-09.14:51:52 zfs set atime=off tank with no issues. With appropriate tuning I also now run my home server (personal email server, samba and nfs server for music/video/documents) which is again i386 with 3 gigs memory with /usr and /var on zfs mirrors. for this I did have to set kern.maxvnodes=4 vfs.zfs.zil_disable=1 vfs.zfs.prefetch_disable=1 vfs.zfs.arc_max=83886080 vm.kmem_size_max=536870912 for it to survive a portsnap fetch portsnap extract without running out of kernel memory. since then its run with no issues. I'm told that FreeBSD/amd64 is a better choice for zfs though as with a 32bit kernel you are more likely to experience problems with KVA shortage than you are RAM shortage when using ZFS. Also see the thread starting: http://lists.freebsd.org/pipermail/freebsd-current/2007-June/073972.html for reports from people using it (back in zune true but its only going to have improved since :) Vince Wojciech Puchar wrote: on FreeBSD 7.0 i mean is it stable enough to be used on FreeBSD/amd64 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
