PFS ON RAID 10
-
i get some new hardware and playing little bit with pfs, and get to the problem
I have
main board with raid controller
2x 2gb ddr2
4x 500gb SATA hdd
5x 1gbps nicsi want to build hi cache proxy server with 500gb web cache
so, i build RAID 10 (mirror stripped)
and trying to install PFS, but when loading cd it just stops, get me to shell
mountroot>and thats it
it seems that pfs can not see raid, is it drivers error in PFS (missing drivers), or something else? I dont think that im doing something wrong?
thanks

i could be completely wrong on any or all of these point but..
i believe BSD, like linux, does not see or ignores fakeRAID http://linux-ata.org/faq-sata-raid.html
some advocate JBOD over RAID0 due to the nature of the disk access http://wiki.squid-cache.org/SquidFaq/RAID
is it necessary to have dynamic/temporary and otherwise useless data like web caches be fault tolerant? at the cost of 2x500GB HDDs? considering also the point about JBOD and performance you may want to reassess
i am by no means an expert on any of these matters so i strongly urge you to wait for someone more experienced to reply, or to do your own research. hope the links help.

I agree with Sentofuno. Buy you a RAID controller supported by FreeBSD. That should help. Raid 5 should give you enough performance. Raid 10 there is going to be two mirrored pairs. There is going to alot of IO. I would go with more disks to give higher performance. You can go with as 3ware 9650SE-8LPML 8 Port Serial ATA RAID Controller (ebay (112 US dollars) or3ware 64 bit controller both conbe found on ebay.
Look there.

thanks guys for your replys,
i didn catch much time to play with it yesterday, but i get to the point when change in BIOS RAID controller to AHCI, then PFS can see 4 disks and raid array??? :Dok, a make install to raid array, and installed boot blocks (tried 6 times, to first, second, *, *, to all, and only to raid, it returns error that cannot install, and success was only when selected first disk), but when PFS starts to boot it stops and write error:
F1 pfSense
F5 Drive 1Default F1:
Not ufs
Not ufsNo /boot /loader
pfSsense/i386 boot
default: 0:ad(0,a)/boot/kernel/kernel
boot:
Not ufs
No /boot/kernel/kernel???
any ideas
thanks -
You where tryng that with a software raid. I would actually get a raid controller that is support by freebsd and connect the disks to that controller. It would be much faster at that point. Also if a drive should fail the controller is going to be making a beeping sound and you connect to the bios of the controller and see exactly which disk has failed.
Software RAID is much sower in comparision to hardware RAID.
