LVM, device-mapper and cmirrord begin to support merging mark/flush request(if DM_INTEGRATED_FLUSH is set) This would increase the write throughput of cluster raid1 based on my own test. dongmao zhang (2): add integrated_flush support to device-mapper cmirrord support DM_INTEGRATED_FLUSH daemons/cmirrord/functions.c | 62 +++++++++++++++++++++++++++++++++--------- daemons/cmirrord/local.c | 9 +++++- lib/mirror/mirrored.c | 4 +++ libdm/libdevmapper.h | 3 ++ libdm/libdm-deptree.c | 8 +++++ 5 files changed, 72 insertions(+), 14 deletions(-) -- 1.7.3.4
