The error messages that might be displayed during NFS hierarchy extension are listed below, along with a suggested explanation for each. Note that these error messages appear when the GUI indicates it is “Executing the pre-extend script….” to validate the hierarchy prior to extending it to the new system.
During NFS Resource Hierarchy Creation on Target Server
|“REQUIRED SOFTWARE” cannot be found or does not have the expected permissions on server “SERVER”
|NFS must be installed on the primary server and all backup servers. Verify that the nfs-utils has been installed.
|The file system “FILE SYSTEM” on template server “SERVER” has a different mount point “MOUNT POINT” on server “SERVER”
|The resources must be created with the same mount point on each server. Either unextend the file system hierarchy from the target server or recreate it with the same mount point on the template and target servers.
|Unable to copy the file “FILENAME” from server “SERVER” to server “SERVER”
| Possible causes:
|The generated id “ID” conflicts with an existing resource id
|The internally generated resource ID for the nfs or hanfs resource has produced a duplicate.
|The export point “EXPORT POINT” is in /etc/exportson the target server “SERVER”
|Remove the export point from the /etc/exports file on the target server before trying to extend the resource.
|The export point “EXPORT POINT” is exported on the target server “SERVER”
|Unexport the export point on the target server before trying to extend the resource.
|Unable to create active/active configurations with NFS v4 exports. Either “TEMPLATE SERVER” or “TARGET SERVER” currently protects an NFS v4 root export.
|Unable to extend the NFS resource from the TEMPLATE SERVER to the TARGET SERVER as one or both of the servers already protects an NFS v4 export and active/active configurations with NFS v4 exports is not supported.
