Re: RELENG_8 / mpt / zpool Errors
The SAS 2008 chip (SAS 6G) is the one that the FreeBSD mps driver has problems with when used with port expanders. It's the older SAS 3G chip that works OK with FreeBSD I think. I had crossed some wires earlier on in our discussion. We do have a SAS 2008 chip in the system already, but it's not the one that's running the external disk boxes (and we are having no problem with those drives). The external disk boxes (the ones that are having the problems) are connect through an LSI SAS 3801E, which is handled by the mpt driver. The mpt driver is what's giving us trouble right now. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Tim Gustafsont...@soe.ucsc.edu Baskin School of Engineering 831-459-5354 UC Santa Cruz Baskin Engineering 317B -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Re: RELENG_8 / mpt / zpool Errors
I don't know what's out there having chosen only one such card for home use. So you'll need to do your own research. Start with looking at any card with the right chip and then look for evidence that people have used said card with FreeBSD. LSI has the SAS 9200-8e, which is based on the SAS 2008 chipset, which the mps (not the mpt) driver claims to support. We are currently using another controller that uses the SAS 2008 chipset in this same box for the internal OS drives and have not had any problems with it. So, that makes me feel good. Does anyone have any recommendation for or against the 9200-8e? -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Tim Gustafsont...@soe.ucsc.edu Baskin School of Engineering 831-459-5354 UC Santa Cruz Baskin Engineering 317B -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Re: RELENG_8 / mpt / zpool Errors
I'm not sure what cards you can get now with the LSI 1068E chip. As LSI branded cards cost more, I went for for the LSI SAS2008 based Supermicro AOC-USAS2-L8i as I new I wasn't going to use port expanders. It could be hard to get cards with the older chip now (you might have to get something second hand). I'm not at all wedded to that card; any card that has two external ports will do for me. The bigger requirement is that it works well with FreeBSD 8.2 and eventually 9.0. If you had your pick of any (reasonably priced) card that had two external ports and would work in my configuration, which would it be? A port expander would be required and just a few older drives in the enclosure. A developer (of which I'm not) would need console access and ability to install new kernels, reboot etc. I can probably swing that, at least for a time, in 3 or 4 weeks. We have hardware on order that I can use to test with for a short while before it goes into production. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Tim Gustafsont...@soe.ucsc.edu Baskin School of Engineering 831-459-5354 UC Santa Cruz Baskin Engineering 317B -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

However, if paid work demands a quicker solution, I'm hoping they'll fund use of the SAS 3G card (cheap) whilst allowing Tim to occasionally work with the SAS 6G card to work on a final solution! I can most likely switch to a different card. Just to make sure I get the right one, do you have a part number of the card that you are recommending? As I mentioned earlier, I was looking around on the LSI site and they have lots of options, but none with a port configuration that I need (2 external ports only). I'd be happy to help with debugging the 6G problem. I could probably install that card into another box and give some developers access to it, but I'd have to rustle up some disks and port expanders to make it a fair test. Ideally we don't want Tim to have to move away from FreeBSD. We want him to help fix the driver. I've been a FreeBSD man since 2.2.5, and I won't be switching off any time soon. :) We have several other FreeBSD servers at this point - 5 to be exact, plus my workstation, and there's talk of adopting it more because of Soracle's abandonment of various projects.
