So, it is not ganesha which is incompatible. NFS kernel client had bugs which were resolved. So, kind of had to find out the right kernel version that supports NFS4.1 mounts by trial and error. - Sriram From: QR <zhbingyin@sina.com> Reply-To: "zhbingyin@sina.com" <zhbingyin@sina.com> Date: Sunday, March 17, 2019 at 12:28 PM To: Sriram Patil <sriramp@vmware.com>, Jeff Layton <jlayton@redhat.com>, ganesha-devel <devel@lists.nfs-ganesha.org> Subject: 回复：Re: [NFS-Ganesha-Devel] Re: Input/output error on CentOS7.2 with nfs4.1 Hi Sriram, Is there any document about which kernel version ganesha supports for using NFSv4.1 mounts? -------------------------------- ----- 原始邮件 ----- 发件人：Sriram Patil <sriramp@vmware.com> 收件人：Jeff Layton <jlayton@redhat.com>, "zhbingyin@sina.com" <zhbingyin@sina.com>, ganesha-devel <devel@lists.nfs-ganesha.org> 主题：Re: [NFS-Ganesha-Devel] Re: Input/output error on CentOS7.2 with nfs4.1 日期：2019年03月17日 10点23分 Yes, you need centos kernel version >= 3.10.0-514 for using NFSv4.1 mounts. - Sriram On 3/16/19, 5:53 PM, "Jeff Layton" <jlayton@redhat.com> wrote: On Sat, 2019-03-16 at 16:14 +0800, QR wrote:

We are getting "Input/output error" when reading regular files on CentOS7.2 with nfs4.1(4.0 is ok).

Is anyone know about this?

Thanks in advance.

nfs version : nfs4.1

I'd suspect a bug in the client with a kernel that old. You may want to update the kernel on the client and test again. -- Jeff Layton <jlayton@redhat.com> _______________________________________________ Devel mailing list -- devel@lists.nfs-ganesha.org To unsubscribe send an email to devel-leave@lists.nfs-ganesha.org
