Hello, I was thinking about read optimization a bit more. Especially for database loads two things are important for performance (besides scema optimization :) ) secure async writes (=HW RAID + BBU) and short access times for reads (SSD or many fast disks). Simply speaking a DRBD device is something like a raid1 over the network where reads are done from one side ONLY. If reads would be done on both sided - it would in theory be possible to double the read rate. This would also warm up the buffer cache on the standby side. A configurable parameter to enable reads on both nodes would be nice to have. Is this planned in future drbd releases ? (I've seen that hot cache is on the roadmap) Robert
