[DRBD-user] replication link stability

Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


I have two servers with dedicated replication link (WiFI - 48Mbit/s). My
clients are connecting via other network link (100Mbit/s) to SAMBA service.

When they are copying files then replication link is very unstable - I can
see a lot of NetworkFailure statuses. Finally, they are disconnected from
SAMBA share (what is strange).

I think that dedicated network link is ok, because when I manually copy
files between two samba locations then copying is fine.

What is the reason of this behaviour? Any solution?

Below you can find my net and syncer section from drbd.conf:

     net {
                max-buffers 2048;
                max-epoch-size 2048;
                unplug-watermark 128;
                sndbuf-size 0;

         syncer {
                c-min-rate 10M;
                rate 10M;
                al-extents 127;
