NFS verification

To verify that the NFS exports work properly, we need to mount them on the openshift.example.com node, which is shown in the following code. If all shares can be mounted without any issues, you can assume that that share was exported properly:

# yum install -y nfs-utils...<output omitted>...# showmount -e storage.example.comExport list for storage.example.com:/exports/nfsvol3 openshift.example.com/exports/nfsvol2 openshift.example.com/exports/nfsvol1 openshift.example.com# mkdir /mnt/{nfsvol1,nfsvol2,nfsvol3}# mount storage.example.com:/exports/nfsvol1 /mnt/nfsvol1# mount storage.example.com:/exports/nfsvol2 /mnt/nfsvol2# mount storage.example.com:/exports/nfsvol3 /mnt/nfsvol3# df -h|grep nfsvolstorage.example.com:/exports/nfsvol1 ...
