startup-config file open failed (Device or resource busy)

[aegkaluk]

Error message:
"startup-config file open failed (Device or resource busy)"

The write to flash processo might have hang or might be in use by another user.

How to fix:

systat               -> check which users are logged in
clear line vty X  -> clear all the users from the router
write                 -> now you can write your config to flash

clear all lines. Any of the sessions is running a process that is writing to flash that might have been hang.
