Warning FailedMount 12s (x39 over 1h) kubelet 10.130.33.13 (combined from similar events): MountVolume.SetUp failed for volume "nfs-pv": mount failed: exit status 32 Mounting command: systemd-run Mounting arguments:-- description=Kubernetes transient mount for / var/lib/kubelet/pods/7b0fcbd3-7382-11e8-80b5-74eacb7559f1/volumes/kubernetes.io~nfs/nfs-pv-- scope-- mount-t nfs 10.130.44.20:/test/mysql-nfs01 / var/lib/kubelet/pods/7b0fcbd3-7382-11e8-80b5-74eacb7559f1/volumes / kubernetes.io~nfs/nfs-pv Output: Running scope as unit run-11918.scope. Mount: wrong fs type, bad option, bad superblock on 10.130.44.20:/test/mysql-nfs01, missing codepage or helper program, or other error (for several filesystems (e.g. Nfs, cifs) you might need a / sbin/mount. Helper program) In some cases useful info is found in syslog-try dmesg | tail or so.

According to the error prompt, check / sbin/mount. File, sure enough, there is no / sbin/mount.nfs file, just install nfs-utils

Solution:

Apt-get install nfs-common

Or

Yum install nfs-utils

After installation, there are several more mount files under / sbin/, such as mount.nfs and mount.nfs4:

[appuser@chenqiang-dev] # cat / sbin/mo

Try kubectl get po again and find out.
