That's apparently an oversight (Bug), there is still a value of 128k hardcoded in drbdmeta. > Will both nodes discuss about the value to use up to 1M, even if I don't > use "--peer-max-bio-size 1M" in drbdmeta ? If you have two nodes, don't use that option to drbdmeta. That option to drbdmeta should NEVER be used, UNLESS you set up a single node DRBD and start to use it as single node, before you even configure and connect the peer. > I wait for your answer to create my resources :-) For any normal use case, using that option to drbdmeta is simply wrong. So don't.
