I have heard reports > of evil at 64k, I wouldn't go there other than with test data. well, my "evil" value is at 32k, crashed my system to a unuseable state. could be related to my 4gb memory in a 32bit system. i think people with 64 bit can go higher. something from my logfile can be read here if it is interesting: http://pastebin.ca/1798794 my x server crashed, and i was not able to do anything anymore related to the raid device. i.e. echo 1024 > /sys/block/md2/md/stripe_cache_size hangs, also cat /proc/mdstat. was a nice crash that stopped my heart for some seconds. thanks to neil for making "resuming" of reshape processes possible. -- 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
