Unmounting NFS File Systems #. This will make the export directory “/home” to be available on the NFS client machine. A solution for using bind mounts with options (such as read-only) in /etc/fstab on systemd systems is presented. For more mount options, and detailed explanations of the defaults, see the man fstab and man nfs pages in the Linux documentation. NAME¶ fstab - static information about the filesystems SYNOPSIS¶ /etc/fstab DESCRIPTION¶ The file fstab contains descriptive information about the filesystems the system can mount.fstab is only read by programs, and not written; it is the duty of the system administrator to properly create and maintain this file. host: ... man nfs Persist mount config in /etc/fstab.

This section may be skipped on most recent distribution. It is possible sometimes you may get this error. Your explanation (reminder) of the details of the various options is easy to understand, too. lookupcache= mode A NFS share can be mounted on a machine by adding a line to the /etc/fstab file.
