Solaris Common Messages and Troubleshooting Guide

NFS mounted callog file Unsupported.

Cause

After installing the Solaris 2.6 software on a system, when users try to start their calendars either with CDE's calendar manager (/usr/dt/bin/dtcm) or OpenWindows' calendar (/usr/openwin/bin/cm), they see this dialog box: 


Calendar :Informational - NFS mounted callog file Unsupported.
Your default startup Calendar file appears to be NFS mounted or
a symlink to the same.  This is Not Supported.
			Continue
The following error is displayed in the console window when the Continue button is clicked: 

date time host rpc.cmsd[pid]: rpc.cmsd : 
	NFS mounted callog file Not Supported - user@host
date time host rpc.cmsd[pid]: rpc.cmsd : 
	NFS mounted callog file Not Supported - user@host
The calendars would have worked under the Solaris software versions including and prior to 2.5.1, however.

Action

It has long been known that NFS-mounted calendars are not supported. The calendar can be corrupted when more than one person uses the calendar at the same time. If two rpc.cmsd daemons write to the callog file at the same time, the file becomes corrupt. However, two rpc.cmsd daemons could be run simultaneously on the Solaris 2.5.1 release, even though this is not a supported configuration.

With the Solaris 2.6 release, this concurrency is no longer an option. rpc.cmsd does not allow the user to start a calendar that is NFS-mounted and produces the previous error message.
