PFS ON RAID 10
i get some new hardware and playing little bit with pfs, and get to the problem
main board with raid controller
2x 2gb ddr2
4x 500gb SATA hdd
5x 1gbps nics
i 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
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?
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.
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??? :D
ok, 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:
F5 Drive 1
No /boot /loader
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.
