Error when saving configuration

[daylight28]

when i tried to save the configuration of one of my AP 1200 access point, i encountered this error message

"Destination filename [startup-config]?

Building configuration...

nv_done: unable to open "flash:/config.txt.new"

nv_done: unable to open "flash:/config.txt.new"

nv_done: unable to open "flash:/private-multiple-fs.new"[OK]

NVRAM Verification Failed"

what is happening to my AP ?

flash corrupt ?

Could be your flash file-system is full.

Check the output of "dir flash:", even with the latest IOS version

there should be more than 2 MBytes free space.

If you find a lot of "crashinfo_*" files you can delete these with

delete /force flash:crashinfo*

Every "crash" writes a file "crashinfo*" to the flash file-system.

These are only useful if you open a SR with the Cisco TAC.

seems like i cant even go to my flash directory

hostname#dir flash

%Error opening flash:/flash (Invalid argument)

The trailing colon is important!

dir flash:

You could also try (w/ or w/o colon):

show flash

[daylight28]

managed to clear all the crash/info files and the AP is online again.

wondering why is there so many crash/info files

residing on the AP.

Hi,

Can you please share how did you manage to clear all the crash/inof. I'm having the same problem and can't use

dir flash: commands.

Thanks,

Bab

Bab,

Are you in enable mode when you invoke the command "dir flash:"?
