Hello, blocking is a normal behavor when you replication link TCP queues becomes full. You may increase the linux kernel defaults like this in /etc/sysctl.conf net.core.rmem_default = 16777216 net.core.wmem_default = 16777216 net.core.rmem_max = 33554432 net.core.wmem_max = 33554432 net.ipv4.tcp_rmem = 131072 16777216 33554432 net.ipv4.tcp_wmem = 131072 16777216 33554432 net.ipv4.tcp_mem = 131072 16777216 33554432 and switch to protocol A. But after about 16MB unwritten data send to secondary it will block. If you switch to drbd 8.4 is is pssible to switch automaticaly to resync with a on-congestion policy. Regards roland
