If we have an asymetrically congested network, we may send P_PING, but due to congestion, the corresponding P_PING_ACK would time out, and we would drop a (congested, but otherwise) healthy connection ("PingAck did not arrive in time.")

The old (optimistic) implementation could shrink the bio size on an primary device. Shrinking the bio size on a primary device is bad. Since there we might get BIOs with the old (bigger) size shortly after we published the new size. The new implementation is more conservative, and eventually increases the max_bio_size on a primary device (which is valid). It does so, when it knows the local limit AND the remote limit. We cache the last seen max_bio_size of the peer in the meta data, and rely on that, to make the operation of single nodes more efficient.

It seems that the real cause of all the issues where that we did not noticed in drbd_try_connect() when the other guy closes one socket if the round trip time gets higher than 100ms.

If there is no replication traffic within the idle timeout (ping-int seconds), DRBD will send a P_PING, and adjust the timeout to ping-timeout. If there is no P_PING_ACK received within this ping-timeout, DRBD finally drops the connection, and tries to re-establish it. To decide which timeout was active, we compared the current timeout with the ping-timeout, and dropped the connection, if that was the case. By default, ping-int is 10 seconds, ping-timeout is 500 ms. Unfortunately, if you configure ping-timeout to be the same as ping-int, expiry of the idle-timeout had been mistaken for a missing ping ack, and caused an immediate reconnection attempt. Fix: Allow both timeouts to be equal, use a local variable to store which timeout is active.

Just deal with it more gracefully, if we fail to add even a single page to an empty bio.

If we fail to send the information that we lost our disk, we have no connection, and no disk: no access to data anymore. That is either expected (deconfiguration), or there will be so much noise in the logs that "Sending state failed" is not useful at all. Drop it. If the reason for a shorter than expected receive was a signal, which we sent because we already decided to disconnect, these additional log messages are confusing and useless. This patch follows this pattern: - dev_warn(DEV, "short read expecting header on sock: r=%d\n", r); + if (!signal_pending(current)) + dev_warn(DEV, "short read expecting header on sock: r=%d\n", r); Also make them all dev_warn for consistency.

Now that we do no longer in-place endian-swap the bitmap, we allow selected bitmap operations (testing bits, sometimes even settting bits) during some bulk operations. This caused us to hit a lot of FIXME asserts similar to FIXME asender in drbd_bm_count_bits, bitmap locked for 'write from resync_finished' by worker Which now is nonsense: looking at the bitmap is perfectly legal as long as it is not being resized. This cosmetic patch defines some flags to describe expectations in finer detail, so the asserts in e.g. bm_change_bits_to() can be skipped if appropriate.

All decisions about sync, sync direction, and wether or not to allow a connect or attach are based on our set of UUIDs to tag a data generation. Log changes to the UUIDs whenever they occur, logging "new current UUID P:Q:R:S" is more useful than "Creating new current UUID".

The "lazy writeout" of cleared bitmap pages happens during resync, and should happen again once the resync finishes cleanly, or is aborted. If resync finished cleanly, or was aborted because of peer disk failure, we trigger the writeout from worker context in the after state change work. If resync was aborted because of connection failure, we should not immediately trigger bitmap writeout, but rather postpone the writeout to after the connection cleanup happened. We now do it in the receiver context from drbd_disconnect(). If resync was aborted because of local disk failure, well, there is nothing to write to anymore.

Protocol A has no P_WRITE_ACKs, but has P_NEG_ACKs. The master bio might already be completed, therefore the request is no longer in the collision hash. => Do not try to validate block_id as request In Protocol B we might already have got a P_RECV_ACK but then get a P_NEG_ACK after wards.
