Hello Everyone, These Patches add support for continuous replication to colo. This means that after the Primary fails and the Secondary did a failover, the Secondary can then become Primary and resume replication to a new Secondary. On a side note, I wrote a Pacemaker Resource Agent for colo which I will post when its ready. I have to say it's quite fun to randomly kill a Node, wait for resync and repeat and see how the VM stays alive all the time. :) Regards, Lukas Straub v5: - change syntax for the position= 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 interface - fix the error message for the position= 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 ignoring requests after failover net/filter.c: Add Options to insert filters anywhere in the filter list colo: Update Documentation for continuous replication block/replication.c | 38 ++++++- docs/COLO-FT.txt | 212 +++++++++++++++++++++++++++---------- docs/block-replication.txt | 28 +++-- include/net/filter.h | 2 + net/filter.c | 92 +++++++++++++++- qemu-options.hx | 10 +- tests/test-replication.c | 52 +++++++++ 7 files changed, 358 insertions(+), 76 deletions(-) -- 2.20.1
