Hi Joel,


I have a problem with resync blocks.



First, I have a 2 node cluster, and node-1 running DRBD 9.1 and node -2 is DRBD 9.2 and protocol C.

and the problem scenario is as follows:
1. node-2 always has application IO
2. node-1 network failure with node-2
3. the network is restored. node-1 is SyncTarget and node-2 is SyncSource
4. then resync process is blocks



You solved the same problem in Commit "7a9ae1a208", but I still have this problem.


So, how do I solve this problem?



Best regards,
zhengbing
