pretty much any smartcommands...I was running something that got all of the smart stats 1x per hour per disk...and this made it crash about 1x per week, if you were pushing the disks hard it appear to make it even more likely to crash under the smart cmds, removing the commands took things up to 2-3 months between crashes. I suspect if you just put a simple smartcmd --all /dev/sdX and ran it a few times a minute if it had the issue it would almost certainly crash in less than a day, I did not figure out the smart cmds were crashing it, someone else's post indicate that they had determined that and I figured out what I had doing smartcmds and removed them and things got much betterr. For finding good vendors, I know others on the md-raid list have given up on cheap and found decent but more expensive controllers. I would expect LSI and Adaptec to care enough about their names to make a decent quality product. There appears to be 4pt (1-8087 pt-jbod/nonraid) adaptec that may be some variant of marvell that is about $130US on newegg, given it is adaptec they may have made the marvell actually work. There are a number of 8pt non-raid cards up around $250-$300 that would probably work great if you wanted to pay that much, these cards have 2x8087 ports and need a 8087->4sata cable cable. Given how nice it is to have a machine that just mostly works without messing around with it I would probably pay the extra for stability. Last time I looked at the 2pt/pciex1 cards I found significant indications of instability enough to expect that I would have to put several hours (or more) of testing/crashing/RMA pain in to figure out which worked. I went so far as crossing out any of the motherboards with non-AMD/non-intel sata ports as I have been burned before on large MB vendors doing a bad job of integrating others (possibly bad) sata ports in, it is a sad state, but it also has been this way for a long time. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
