Cisco WLAN AP2802 - flash full - mobility express

[guidolippert]

Hello, i have a problem with a ap2802e. I have uploaded the wrong update file for mobility express, not the small tar file, for updating rather the tar bundle, about 150MB. Now i have the problem with a full flash, no space left for logging or creating config files.

the delete command does not work for files. what can i do to free some space or reflash the device?

resetting the device, mode button pressed more than 20sec does not help.

thank you

the delete command does not work for files.

What do you mean?

I am guessing you are not able to delete them because they are directories. 

You can try this command:

delete /force/recursive flash:(directoryname)

example:

AP# delete /force /recursive flash:images

https://supportforums.cisco.com/discussion/10343871/deleting-directory-flash

You could also try:

format flash:

You'd want to be careful with that.  It is a scorched earth approach.

Hello Jonathan,

the format command does not exist. 

AP70DB.9897.E276#format % Unrecognized command

also if i try to delete a file from flash: the delete command does not accept "flash:"

I know these commands from older wlan ap, like the 1140, or the 2700 series, and these commands work on the older models.

So i have no idea how to clean up the flash to free up some space

AP70DB.9897.E276#delete flash:config
                        ^
% Invalid input detected at '^' marker.
AP70DB.9897.E276#

I would do it from ROMMON then. 

I do most of my AP work (with regards to files) in ROMMON.  It just works.

[guidolippert]

I think there is no rommon. Mode button pressed longer than 20 seconds is full factory reset.

There is a Cisco U-Boot, when i hit the escape key on boot.

I am facing the same problem. However, I don't think it's flash:/ that is full.

I was trying to upgrade a 2802i running MobExp 8.3.102.0 to 8.5.103.0. It was able to update all of the APs joined to it, but always failed on the local AP/controller. I found I was receiving "tar: write error: No space left on device" when attempting the upgrade.

I found this forum post in which someone stated they worked around the problem by loading a CAPWAP image on the AP, then converting it back to MobExp 8.3. I'm consoled in trying to do this now but am attempting to jump right up to 8.5, but I'm getting the same "no space" message.

There is plenty of free space on flash:

Filesystem                Size      Used Available Use% Mounted on
flash                    57.5M    432.0K     54.1M   1% /storage

I reloaded into the u-boot prompt and I think the filesystem that needs to be examined/cleaned up is UBI, but I'm having a hard time getting into it, mostly due to not knowing what the volume is called:
