A quick follow up. I've been playing w/ zfsonlinux running on a Debian squeeze machine for a little while. I use the ppa for Ubuntu for the moment (https://launchpad.net/~zfs-native/+archive/stable). My test machine is totally out of spec (and out of time): dell dimension 3000 (celeron), 1gb ram, pci sil3124 SATA port multiplier card, 2 Lian-li ex50 enclosures (5 drives, based on a JMicron controller I think). Realtek pci gigabit Ethernet board. It runs a 32bit kernel. I've used both the Debian stock 2.6.35-i686 kernel and the xen-4.0 kernel. I thought I had 10 drives at hand, but some are shot, so right now I have only loaded the enclosures w/ 3 WD Green drives each.
Everything says zfs should not be working in these conditions. Well, albeit a bit slowly, the machine has been transferring data via rsync for 24hrs now, and all is well. For a while I was playing at the same time 7 or 8 mp4 videos from the pool, over the nfs export. Worked perfectly. I am now certain I will be migrating my server's hw Raid5 setup to a software zfs system, under Linux. (On this low-end system it didn't work well at all, at first. I had to add vmalloc=512M to the boot parameters. I had to load the zfs kernel module with option nocacheflush=1, else throughput over the single PCI link was really too low. I also tested on a recent machine, with a 6 core CPU, 4gb ram and a PCI-Express port multiplier card. Ubuntu 64 bit. Worked out of the box, and quite fast indeed.) ------------------------------------------------------------------------ epoch1970's Profile: http://forums.slimdevices.com/member.php?userid=16711 View this thread: http://forums.slimdevices.com/showthread.php?t=92904 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
