I have 4 750GB drives in a raid 1+0. I've had drive failures due to a bad SATA cable (easily recoverable, of course), another due to a proper drive failure, and its replacement is already showing SMART Raw_Read_Error_Rate and Hardware_ECC_Recovered counts. "raid 0 and pray" is good advice for just 2 drives :) . In that case, I'd also suggest having a spare already on hand, and adopting the policy that a drive failure is a non-maskable interrupt, that must be dealt with before anything else. > Ongoing monitoring? /me ♥ logwatch and smartd, but I'm an amateur at this stuff. > Is ZFS so great and wonderful that it > is worth running BSD (instead of Linux) on a backup server? ZFS always seemed awesome. But, Apple stopped using ZFS, and Oracle already cared about btrfs before buying Sun. Is it even an option? -- ...jsled http://asynchronous.org/ - a=jsled; b=asynchronous.org; echo ${a}@${b}
