I have a dedicated, consumer hw, media/file server with a 6 drive raid6 of 2tb drives, all plugged directly into the sata ports on my motherboard, an asrock z77. A while back I had a problem which seemed like cascade failure of drives, but Stan Hoeppner and Phil Turmel helped me to figure out it was a PSU having gone bad and delivering dirty power. After replacing the PSU things worked fine, or so I thought. At some point I noticed I have quite a bit of trouble making it through a resync without the machine locking up. When I realized it wasn't tied to a resync in particular but any extended heavy I/O, I lowered the sync_speed_max to 10,000, I was able to get through a repair (no mismatches found!). I'm guessing that the motherboard has some problem (perhaps originating from the bad PSU?), and I want to switch to a dedicated HBA card to make this more modular. Stan had suggested the LSI SATA/SAS 9211-8i in many threads in the archives. If I use this card as my HBA, is there any particular motherboard which would be better suited than others? thanks -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
