Subject: when an osd is started up, IO will be blocked
Date: Thu, 22 Oct 2015 22:43:42 +0800 [thread overview]
Message-ID: <5628F61E.1060708@gmail.com> (raw)
Hi all,
When an osd is started, relative IO will be blocked.
According to the test result,the larger iops the clients send , the
longer it will take to elapse.
Adjustment on all the parameters associate with recovery operations was
also found useless.
How to reduce the impact of this process on the IO ?
Thanks and Regards,
WangSongbo
