You should move directly to 9.0.20, the 9.0.16 release is missing approximately 1 year of bug fixes that were applied in the meantime, including:
* Fix UUID handling of a diskless primary that has no peer with usable data may not touch the current UUID * Fix resync-after dependencies; cross-resource dependencies and missing resources * Fix resync when the sync source suddenly connects to a more recent data set via an other connection and becomes sync target on that other connection; pause first resync; fix wrong display of negative resync progress percentage in this case * Fix volume numbers between 32767 and 65534 * Fix the data integrity implementation; it was broken since drbd-9.0 and reported only false positives * Fix for a corner-case when a promote action happens concurrently with a reconciliation resync * Fix an IO deadlock under memory pressure * Fix disconnect timing in case the network connection suddenly drops all packets * Fix some misbehavior that surfaced with Ahead/Behind * Fix potential spinlock deadlock in IRQ * Fix detection of unstable resync * Fix possible stuck resync when resync started from an other secondary and later continued from a primary * Fix NULL dereference with disk-timeout enabled; was introduced in 9.0.9 * Fix quorum tie-breaker diskless logic for settings other than "majority" * Fix dax_direct_access() error return check * Fix resync stuck at near completion; bug was intorduces with 9.0.17 * Fix a case of false split brain detection [...] * Fix after weak handling to not interfere with reconciliation resyncs * Fix resync to make progress after it was paused by an other resync operation * Fix restore of D_OUTDATED when the resource first only attached and then the peer objects are created (in contrast to the usual, new-peer, attach, connect) * Fix a small memory-leak when creating peer devices * Fix a possible information leak of kernel memory that pads net-link packets br, Robert _______________________________________________ Star us on GITHUB: https://github.com/LINBIT drbd-user mailing list [email protected] https://lists.linbit.com/mailman/listinfo/drbd-user
