This means that after the Primary fails and the Secondary did a failover, the Seconda= ry can then become Primary and resume replication to a new Secondary. Regards, Lukas Straub v7: - clarify meaning of ip's in documentation and note that active and hidde= n images just need to be created once - reverted removal of bdrv_is_root_node(top_bs) in replication and adjust= ed the top-id=3D parameter in documentation acordingly v6: - documented the position=3D and insert=3D options - renamed replication test - clarified documentation by using different ip's for primary and seconda= ry - added Reviewed-by tags v5: - change syntax for the position=3D parameter - fix spelling mistake v4: - fix checkpatch.pl warnings v3: - add test for replication changes - check if the filter to be inserted before/behind belongs to the same in= terface - fix the error message for the position=3D parameter - rename term "after" -> "behind" and variable "insert_before" -> "insert= _before_flag" - document the quorum node on the secondary side - simplify quorum parameters in documentation - remove trailing spaces in documentation - clarify the testing procedure in documentation v2: - fix email formating - fix checkpatch.pl warnings - fix patchew error - clearer commit messages Lukas Straub (4): block/replication.c: Ignore requests after failover tests/test-replication.c: Add test for for secondary node continuing replication net/filter.c: Add Options to insert filters anywhere in the filter list colo: Update Documentation for continuous replication block/replication.c | 35 +++++- docs/COLO-FT.txt | 224 +++++++++++++++++++++++++++---------- docs/block-replication.txt | 28 +++-- include/net/filter.h | 2 + net/filter.c | 92 ++++++++++++++- qemu-options.hx | 31 ++++- tests/test-replication.c | 52 +++++++++ 7 files changed, 389 insertions(+), 75 deletions(-) =2D- 2.20.1
