Let me correct a point I made badly the first time around, I value the data integrity provided by mirroring (I have always used mirrored drives for data and OS on my home servers), I don't know how much the end-to-end checksumming buys me, but it is not a compelling feature. In other words, I didn't choose ZFS because of the end-to-end checksumming, I chose it for the ease of management and flexibility in configuration. The checksummed data is just a bonus that came along for the ride :-) Remember, this thread was essentially "Why would a home user choose ZFS over other options"... I tried using software mirrors under Linux ... maybe I was spoiled by Disk Suite / Solaris Volume Manager, but I found the Linux software mirrors clunky and unreliable (when installing the OS, the metadevices came up in one order, after booting off of the hard disk they came up in another order, leaving my mirrored root unmountable). I'm not a big fan of hardware "RAID" as I have seen terrible performance out of HW RAID cards and from the OS layer you need additional hardware vendor drivers to really manage and monitor the drives (if you even can from the OS layer, I hate rebooting, even home servers). Just one geeks opinion. -- Paul Kraus Albacon 2008 Facilities _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
