Hi malahal, thanks for your reply. CentOS7.5 doesn't has this issue, so this seems a bug in kNFS. I need to find a solution for CentOS7.2, so I search the release notes for 7.3~7.6, and fail to find anything about this. Then I find bug https://bugzilla.redhat.com/show_bug.cgi?id=1519701, but the bug is not confirmed yet. So could anyone tell me how to find the link for this issue? Thanks in advance. -------------------------------- ----- 原始邮件 ----- 发件人：Malahal Naineni <malahal(a)gmail.com&gt; 收件人：zhbingyin(a)sina.com 抄送人：ganesha-devel <devel(a)lists.nfs-ganesha.org&gt; 主题：[NFS-Ganesha-Devel] Re: rsize and wsize on centos7.2 not working 日期：2019年09月25日 13点28分 I remember an issue like this with early shipments of RHEL7. I recall it as a defect in kNFS, My memory could be wrong though. These are exchanged very early on, so I imagine this is due to NFS client (Centos 7.2). Try with Centos 7.6, if you don't see this issue then it is clear where the issue is.

The problem is who splits the 1MB request to 4 requests(256KB)? Is anyone know about this? Thanks in advance.
