Introduction
When some configuration changes made to the AP and tried to save the changes, got message on the AP: "Error writing new config file "flash:/config.txt.new" nv_done: unable to open "flash:/config.txt.new" nv_done: unable to open "flash:/private-multiple-fs.new"[OK]". What does the message mean?
Resolution
This error message indicates that there is no space in the Flash to store the new configuration. Try to delete any old crash files that exist. Or, if there is more than one Cisco IOS Software version, delete the one that you do not use. Issue the dir flash command to determine if there are any old exception crashinfo files that can be deleted or old images that are not in use. This can free some space on the Flash. Issue the dir flash command in order to determine if there are any old exception crashinfo files that you can delete or old images that are not in use. Issue the write memory command in order to free up space so that you can write the configuration into memory.
To free up space to write configuration into memory, issue the write memory command.
