It's not that long, here's one:
$ sudo drbdsetup /dev/drbd0 show
disk {
size 0s _is_default; # bytes
on-io-error pass_on _is_default;
fencing dont-care _is_default;
max-bio-bvecs 0 _is_default;
}
net {
timeout 60 _is_default; # 1/10 seconds
max-epoch-size 2048 _is_default;
max-buffers 2048 _is_default;
unplug-watermark 128 _is_default;
connect-int 10 _is_default; # seconds
ping-int 10 _is_default; # seconds
sndbuf-size 0 _is_default; # bytes
rcvbuf-size 0 _is_default; # bytes
ko-count 0 _is_default;
after-sb-0pri discard-zero-changes;
after-sb-1pri consensus;
after-sb-2pri disconnect _is_default;
rr-conflict disconnect _is_default;
ping-timeout 50; # 1/10 seconds
}
syncer {
rate 20480k; # bytes/second
after -1 _is_default;
al-extents 257;
}
protocol B;
_this_host {
device minor 0;
disk "/dev/here/customer";
meta-disk "/dev/here/customer_meta" [ 0 ];
address ipv4 v3a:45000;
}
_remote_host {
address ipv4 v3b:45000;
}
(disc names & IP addresses changed slightly)
