Installing EMC Celerra results in "Operation not permitted" error using ClearCase

Troubleshooting


Problem

Attempts to install EMC Celerra Dart group results in IBM Rational ClearCase cleartool mkview and mkelem errors such as "Operation not permitted".

Symptom

cleartool mkview fails with:

cleartool: Error: unable to set ownership of file
/nasdevice/viewname.vws: Operation not permitted.  

cleartool mkelem fails with:

2013-02-24T17:46:43-05:00 vob_server(995352): Error: unable to set        
ownership of file c/cdft/34/15/tmp_1081356.174: Operation not permitted.  
2013-02-24T17:46:43-05:00 vob_server(995352): Error: Unable to create    
container /nasdevice/prod.vbs/c/cdft/34/15/tmp_1081356.      
174: Operation not permitted.

Cause

EMC Celerra setting changed when new DART group was installed.

When the new Dart group is installed on the EMC Celerra NetAPP during a maintenance upgrade, it can result in the parameter, rstchown being set to default of 1. This can interfere with proper NFS access with ClearCase.

Note: When using NFS, be aware that the operating system controls privileges to file ownership. Therefore most Linux, Solaris and NAS machines that are NFS servers, will not allow a successful cp -p for retaining ownership (or chown by a normal non-root user) when that parameter is set to 1.

Diagnosing The Problem

Check the setting of the parameter rstchown on the EMC Celerra netAPP.
The default setting of 1 will not allow ClearCase to change the user id when needed.

Resolving The Problem

On the EMC Celerra, change the rstchown parameter setting to 0.

Note: This parameter applies to NFS, but not to CIFS.
