I thought my problem was that the output buffer was full: "DRBD’s protocol A is asynchronous, but the writing application will block as soon as the socket output buffer is full (see the sndbuf-size option in drbd.conf(5)). In that event, the writing application has to wait until some of the data written runs off through a possibly small bandwidth network link." So if I understand this correctly, the issue could be that my primary hadn’t received the ACK for the block and was rewriting it (as is frequent for a database). Is there any way I could ascertain whether that is the case before I recompile and reinstall (which is no trivial matter for that database)?
