When reviewing resources in SAS Environment Manager, you might encounter one or more Network File System (NFS) mount resources that are listed as unavailable. However, if you access the host server directly, you can navigate to the NFS share and access the share normally.
When you encounter this problem, you might see lines resembling the following (where nfs_server and nfs_mount are replaced with the NFS server host name or IP address and mount point, respectively) in the log file for the SAS Environment Manager Agent:
Failed to invoke getMountedFileSystemUsage[/nfs_mount]: <nfs_server>:/nfs_mount nfs server unreachable: /nfs_mount
Note: The SAS Environment Manager Agent log file can be found by default at the following path: SAS-configuration-directory/LevN/Web/SASEnvironmentManager/agent-5.8.0-EE/log/agent.log
The process that the SAS Environment Manager uses to access information about the NFS share uses a call specific to NFS Version 2. In some cases, Version 2 calls are blocked by the NFS server, preventing the SAS Environment Manager agent from connecting at all.
In order to circumvent this issue, NFS Version 2 must be enabled on the NFS server hosting the files that are being shared.
