See also commit from 2009-08-15 "drbd_uuid_compare(): Do not full sync in case a P_SYNC_UUID packet gets lost." We saw cases where the History UUIDs where not as expected. So the detection of the special case did not trigger. With the sync UUID no longer being a random number, but deducible from the previous bitmap UUID, the detection of this special case becomes more reliable. The SyncUUID now is the previous bitmap UUID + 0x1000000000000. Rule 5a: Cs = H1p & H1p + Offset = Bp Connection was lost before SyncUUID Packet came through. Corrent (peer) UUIDs: Bp = H1p H1p = H2p H2p = 0 Become Sync target. Rule 7a: Cp = H1s & H1s + Offset = Bs Connection was lost before SyncUUID Packet came through. Correct (own) UUIDs: Bs = H1s H1s = H2s H2s = 0 Become Sync source. Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com> |
