Open System Services NFS Management and Operations Guide

Cause
The attempted operation would increase the size of the affected file beyond the maximum file
size.
Effect
Attempted operation fails.
Recovery
Either create a new file with larger extents and reload it, or increase the current file’s maximum
number of extents by using the File Utility Program (FUP) ALTER command.
When a file is created by an NFS client, the primary and secondary extent sizes and the maximum
number of extents with which the file is created can be either specified by the client or not
specified. If these values are not specified by the client, they assume default values.
Because the default values for these extent-related parameters are specified for each server when
the server is added to the subsystem, these values can differ for each NFS file system.
To change the default values for these extent-related parameters, the server must be stopped
(using the SCF STOP SERVER command). The default values for these parameters can then be
changed using the SCF ALTER SERVER command. Any files created after the server is restarted
(using the SCF START SERVER command) are created with the new default extent values.
NFS2 Error 28
No space left on device. No free space is left on the device.
Cause
An attempt was made either to expand an existing file or to create a new file or directory, and
the device that was to contain the file or directory did not contain sufficient contiguous free space
to permit allocating the space needed.
Effect
Attempted operation fails.
Recovery
Do one of these:
• Purge unneeded files from the device containing the affected fileset and have the user retry
the operation.
• Have the user mount a different fileset, containing free disk space, and retry the operation.
NFS2 Error 30
Read-only file system. The caller attempted a write to a read-only file
system.
Cause
The caller attempted to modify a file or directory in a fileset that is mounted as read-only.
Effect
Attempted operation fails.
Recovery
For the attempted operation to be successful, either the fileset’s server must be configured to
allow modification of its files and directories or the file that was to be modified must be moved
to a fileset that allows write access.
NFS2 Error 45
Operation not supported. The caller attempted an NFS operation that is
not supported by the OSS NFS subsystem.
