From mboxrd@z Thu Jan 1 00:00:00 1970 From: dongmao zhang Date: Thu, 26 Sep 2013 18:53:27 +0800 Subject: [PATCH 0/4] LVM/cmirrord support write improvement. Message-ID: List-Id: To: lvm-devel@redhat.com MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit These patches work with dm-log-userspace enhancement. LVM, device-mapper and cmirrord begin to support merging mark/flush request and delaying the clear request. This would increase the write throughput of cluster raid1 based on my own test. dongmao zhang (4): cmirrord add support_delay_clear option cmirrord create new function _clog_flush add support_delay_flush to device-mapper cluster LVM use flag DM_SUPPORT_DELAY_FLUSH daemons/cmirrord/functions.c | 60 ++++++++++++++++++++++++++++++++--------- lib/mirror/mirrored.c | 4 +++ libdm/libdevmapper.h | 3 ++ libdm/libdm-deptree.c | 8 +++++ 4 files changed, 62 insertions(+), 13 deletions(-) -- 1.7.3.4
