545398784 bytes total (2711552 bytes free)

Is this mean im low on storage? what files/logs that should be cleanup?

Note: Under Troubleshooting-> Core Dump and System Report - this is empty

Thank you in advance.

- Delete *.crash and *.log (no harm)

Re: C9105 Wireless Controller - %PLATFORM-1-NOSPACE: bootflash : no s

kish02 — Tue, 23 Apr 2024 05:52:15 GMT

Thanks for the reponse but .crash and .log files are only KB files, did not do much

Re: C9105 Wireless Controller - %PLATFORM-1-NOSPACE: bootflash : no s

Mark Elsen — Tue, 23 Apr 2024 05:56:40 GMT

- Content of tracelogs directory can be deleted too ,

Re: C9105 Wireless Controller - %PLATFORM-1-NOSPACE: bootflash : no s

kish02 — Tue, 23 Apr 2024 06:08:27 GMT

it's empty

Re: C9105 Wireless Controller - %PLATFORM-1-NOSPACE: bootflash : no s

kish02 — Tue, 23 Apr 2024 06:18:47 GMT

In show file systems i have this allocation for bootflash: 545398784

dir bootflash: has only 53477376 as the largest file, any idea where's the rest of the space?

Re: C9105 Wireless Controller - %PLATFORM-1-NOSPACE: bootflash : no s

Mark Elsen — Tue, 23 Apr 2024 06:24:43 GMT

- Check if you have older software versions on it (such as binaries) and delete them too , and or anything with *log* in it ,

Re: C9105 Wireless Controller - %PLATFORM-1-NOSPACE: bootflash : no s

Mark Elsen — Tue, 23 Apr 2024 06:31:32 GMT

>....53477376 (largest file)
- What is the name of this largest file (can't immediately find it)

Re: C9105 Wireless Controller - %PLATFORM-1-NOSPACE: bootflash : no s

kish02 — Tue, 23 Apr 2024 06:32:57 GMT

filename is .USWAP.img

Re: C9105 Wireless Controller - %PLATFORM-1-NOSPACE: bootflash : no s

Mark Elsen — Tue, 23 Apr 2024 06:47:22 GMT

>...filename is .USWAP.img
- Ok that one must stay ; I also noted an ap_images: directory , note that the EWC AP must make client ap images available using a tftp server as a 'relay' and not maintaining the images by itself. If there is anything in there , then remove it all ,

Re: C9105 Wireless Controller - %PLATFORM-1-NOSPACE: bootflash : no s

kish02 — Tue, 23 Apr 2024 06:57:37 GMT

nothing's in there as well

Re: C9105 Wireless Controller - %PLATFORM-1-NOSPACE: bootflash : no s

Mark Elsen — Tue, 23 Apr 2024 08:11:28 GMT

- Well for the time being I can only advise to do a reboot too (if there has been a long uptime for instance) ; which can sometimes include cleanup actions on the bootflash. Otherwise involve TAC , or others may bump in ,

kish02 — Tue, 23 Apr 2024 13:05:44 GMT

@Mark Elsen thank you for your assistance. I had rebooted the AP that was acting as controller but same problem. For now, I have switched the other AP as the controller. Will check further that one device.

Re: C9105 Wireless Controller - %PLATFORM-1-NOSPACE: bootflash : no s

Mark Elsen — Tue, 23 Apr 2024 14:44:46 GMT

- Ok, you may for instance factory reset it and re-install ,

Re: C9105 Wireless Controller - %PLATFORM-1-NOSPACE: bootflash : no s

Rich R — Tue, 23 Apr 2024 21:17:26 GMT

Also delete anything in core directory.

And do "install remove inactive" - unlikely to find anything else but worth doing to be sure.

EWC is inherently limited because it's just an AP not a proper WLC.
You didn't mention what version you're running and what version it was upgraded from?
If you didn't follow the recommended upgrade path then the flash partition may be smaller than it should be.
eg: https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/17-9/release-notes/rn-17-9-9800.html#Cisco_Concept.dita_59a2987f-2633-4630-8c7b-a8e8aecdeaf7

And like @Mark Elsen says, if all else fails do a factory default reset and then restore your config (or simply sync from the other AP). Flash running out is a common "feature" of Mobility Express (the previous incarnation for Wave 2 APs) and EWC and probably one of the reasons Cisco has abandoned it on the latest models of APs.
