I would have thought - that so long as the array is done in hardware, and has a suitable number of drives in it - then the usual RAID 5 rules apply, i.e. you take a 'nasty' hit on writes (when compared to reads) - but _overall_ the array is usually faster... ;-) I don't think putting the 'root' filesystem on it (if supported) would be any better / worse than other filesystems (e.g. /usr etc.) - and if I was given the choice (i.e. had the hardware) it would be there allready... <grin> (i.e. go for the redundancy... Afterall - the root FS is pretty important... ;-) Regards, Karl Pielorz Brandon Huey wrote: > > what performance issues are there when the root filesystem in on a > RAID-5 array? > i'm mainly wondering if there are performance hits big enough to lessen > the benefit of redundancy. > > thanks, > -bh > > > > -- > > Brandon Huey Epigram, Inc. > bh@epigram.com +1 408 720 3027 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
