I don't know what kind of hardware or OS Doug used, but I'll just throw this out there and see what happens... A really common mistake for people to make when implementing a ZFS server is to put the wrong OS on the wrong hardware. Even in the day when Dell sold solaris as a supported OS on their servers... You can bet Dell servers didn't get the same kind of treatment and production usage in the Solaris development & support groups. Consequently, when I bought solaris on a Dell server, I had the same stability issues Doug described. At first, it was weekly crashes, until we disabled the on-board broadcom NIC in favor of an add-on Intel NIC. After that change, it's only monthly crashes. Most people experiencing such stability issues are essentially trying to make the system work on generic hardware. Even Dell, HP, or IBM big name hardware counts as "generic" in this context, because it's not what's the primary focus of the development & support groups. There are only three configurations I would recommend for production usage: * Solaris on Oracle hardware (Still cheaper than netapp) * Nexenta on Silicon Mechanics hardware (consult your Nexenta rep for recommendations) * Solaris inside a VMware or VirtualBox virtual machine Anything else, and you might be lucky... Many people report perfect success. But I feel you're taking your chances by experimenting. FWIW, the ability to run on generic blackbox hardware is still an attraction. In a pinch, you know you are not dependent on proprietary hardware to restore something or experiment with some new feature. But it's not what I would recommend for production. _______________________________________________ Tech mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
