Apparently, you used the default values when you initially created the DRBD meta data for this installation. Since you had only two nodes listed in the configuration file and did not specify otherwise, drbdadm created meta data for a two node cluster. Then you added another node to the configuration file, and now you have three nodes in the configuration file, so drbdadm creates meta data for a three node cluster. This will create meta data with 2 peer slots instead of only 1 peer slot, which requires approximately twice the amount of space. Since you are using internal meta data, the net size of the DRBD device will be smaller. You have two problems here: 1. The net size of the storage on the third node is smaller than on the other two nodes, so DRBD can not resync to that node 2. The other two nodes have only one peer slot each, so they cannot connect to a third node You need to recreate the meta data with at least 2 peer slots to run a three node cluster. To make space for the additional peer slots, you will have to either - increase the size of the storage device or - decrease the size of the data (e.g. filesystem) on the storage device or - switch to external meta data br, Robert _______________________________________________ Star us on GITHUB: https://github.com/LINBIT drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
