ceph群集变慢,网卡速率排查

下载并安装EPEL

 wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
 
 rpm -ivh epel-release-latest-7.noarch.rpm
 
 yum repolist

##检查是否已添加至源列表

OK,检查好已添加至源后就可以进行yum安装了

服务器端操作:

yum -y install iperf
iperf -s

客户端操作:

yum -y install iperf
iperf -c server_ip -t 30

//-t 测试时间

//server_ip为服务端的ip

如下所示万兆卡传输正常

[root@ceph-2 ~]# iperf -c ceph-1 -t 3
