Asynchronous Block-Level Storage Replication
f235b76900
This has been found by testing. In extremely rare cases, such after crashes at the "wrong moment" or after defective /mars filesystems, the replay link could show a different length than the corresponding versionlink. The versionlink wouldn't be updated anymore when additionally the logfile has the same length than the replay link. The incorrect versionlink will then lead to a lock. Fix the problem by using the _minimum_ of all length indicators. For safty, or when in doubt, replay more data, which will in turn update the versionlink again to its correct value. |
