How to Test NFS Mounting
Each Delphix engine provides a read-only test NFS share named 'public' which is used to test the ability to mount NFS shares on each target host.
In the event of mount failures during VDB operations, this test NFS share can also be used as part of manual troubleshooting to confirm that NFS mounting is working correctly for the Delphix OS user on that host. Details of how to manually mount this NFS share on a target host are provided in this document.
Prerequisites
The 'public' NFS share is used to test NFS mounting on target hosts running Linux or UNIX. Delphix does not use NFS with Windows target hosts.
This document assumes that 'sudo' is being used to provide a privilege elevation capability on the target host. If instead another privilege elevation tool is being used, substitute the appropriate command into the examples below in place of 'sudo'.
The Delphix OS user on the target host must be configured with the appropriate privilege elevation permissions to be able to run the 'mount' command with the required options.
A suitable mountpoint directory must be created for the test mount. The examples below use /mnt/delphix/test but this should be changed as appropriate for your environment. The Delphix OS user must have sudo privileges to be able to mount filesystems to the chosen mountpoint directory.
To Test NFS Mounting
The following commands can be run as the Delphix OS user to mount the public test share on the target host. Provide the IP address or fully qualified domain name of the Delphix engine in place of delphix_engine_ipaddr.
Linux:
sudo /bin/mount -o nosuid,tcp,vers=3 delphix_engine_ipaddr:/public /mnt/delphix/test
Solaris / AIX:
sudo /usr/sbin/mount -o nosuid,proto=tcp,vers=3 delphix_engine_ipaddr:/public /mnt/delphix/test
HP-UX:
sudo /sbin/mount -o nosuid,proto=tcp,vers=3 delphix_engine_ipaddr:/public /mnt/delphix/test
To unmount the NFS filesystem after testing:
Linux:
sudo /bin/umount /mnt/delphix/test
Solaris / AIX / HP-UX:
sudo /usr/sbin/umount /mnt/delphix/test
