Looks like we should have updated that a while ago, it's actually 32 (which results in 496 pairs)
This is a per-resource limit. One resource can be connected to 31 peers, but another resource on the same server could be connected to another 31 different peers. Regarding LINSTOR, which acts as the management layer for some DRBD installations, the maximum number of nodes in a cluster is in practice limited by the effects of other limits, such as the maximum message size, the amount of memory available, various performance figures, etc. The theoretical absolute maximum would be 2,147,483,647 nodes, which is virtually impossible to reach in any practical application. _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
