Clearly DRBD > is working properly, but the read balancing feature just fails outright. Replying to my own message again, but I figured out what is causing this. In order to do performance testing, I was doing this: echo 3 > /proc/sys/vm/drop_caches Then any command that wanted information from the DRDB mount would fail with "Resource temporarily unavailable" on the first attempt. Subsequent attempts work. This tells me there's some kind of assumption DRBD 8.4.1 is making about the system cache that it shouldn't be. I'm tempted to submit this as a bug, but I would feel better if someone else could confirm this behavior. -- Shaun Thomas OptionsHouse | 141 W.
