I had initial problems with a Promise SX6000 controller with the i2o block driver and I also tried their source pti_st.o code but never got it to compile. I emailed promise and got a response back quite quickly which provided me with a new version of the source code version, plus beta drivers they themselves compiled for redhat 7.3 and redhat 8.0 kernels. I have today started using the redhat 8.0 kernel driver and it seems to work very well. Write performance is approx 15 meg/s to a 5 times 120gig drive stripe (seems a bit on the low side if you ask me but that's ok anyway, perhaps ext3 is slowing things down). I recommend anyone who have problems with their SX6000 to do the same. I made the filesystem with just mke2fs -j and no raid options, is the "stride" options anything I should use? Does it provide better performance? (I tried finding some information on this, but the mke2fs man page is so spread that all the search engines give me are copies of the man page). -- Mikael Abrahamsson email: swmike@swm.pp.se - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
