Description

I wanted to run the test cases ..

Next on Ubuntu, Rhel machine (post installation of dependencies ), try out the below ,

git clone git://git.hpdd.intel.com/fs/lustre-release.git
cd lustre-release/
sh autogen.sh
./configure --disable-server
make

Next change to tests folder
cd lustre-release/lustre/tests

[root@pts00433-vm5 tests]# ./sanity.sh

So our multi node luster set up is as below
1. Machine 1 : Acting as Management server( MGS) , Management target ( MGT ) ,Metadata server( MDS) , Metadata target ( MDT ) - CentOS6.6 x86-VM1 - 10.51.225.95 -x86_64
2. Machine 2 : Acting as - Object Storage Server ( OSS ) , Object Storage Target ( OST ) CentOS6.8 x86-VM2 - 10.51.225.96 - x86_64

Lustre Clients
3. Machine 4 : Acting as lustre client - Ubuntu 16.04.1 LTS (Xenial Xerus) - 10.77.67.146 - ppc64le
4. Machine 5 : Acting as lustre client - Red Hat 7.2 - 10.77.67.129 -ppc64le

Can anyone help me point me how to execute sanity.sh script on this lustre client machine
