It looks like you're facing two separate issues:
Flash Disk Quota Exceeded: Your Cisco ISR 4321 has exceeded its flash disk quota during boot, which is preventing further operations from being performed due to a lack of free space.
Read-Only File System: The command request platform software package clean is failing because it cannot create the required temporary directory (.CLEANUP_IN_PROGRESS) due to the file system being mounted as read-only.
Let's address both issues step-by-step:
1. Resolving the Flash Disk Quota Exceeded Issue
The error message %FLASH_CHECK-3-DISK_QUOTA: Flash disk quota exceeded means that there isn't enough free space on the bootflash to continue normal operation. You need to clean up files manually to free up space. Here’s how you can do it:
Step 1: Verify Disk Usage
First, confirm the disk usage and check which files are taking up space:
Show the disk usage on the device:
bash
dir flash:
This will show you a list of all the files on the bootflash and their sizes. Take note of large files like old IOS images, logs, or old configuration backups.
Check the filesystem usage:
bash
show file systems
This will show the amount of space used and free on each file system. Look for any file system that is nearly full, especially bootflash.
Step 2: Clean Up Old Files
Here are some common files you can delete to free up space:
Old IOS images: Check for old or unused IOS images. These images can often be quite large.
bash
dir flash: # List files in the flash directory
If you find old image files that are no longer required, you can delete them:
bash
delete flash:<filename>
Be sure to only delete the images that are not being used as the current boot image.
Old configuration backups: Sometimes configuration backups or other old files can accumulate over time.
Delete unnecessary backups:
bash
delete flash:<backup-file>
Log files: Cisco devices can generate large log files. Check for and clean up debug logs or syslogs.
bash
dir flash:/logs
delete flash:/logs/*
Step 3: Reboot After Cleanup
Once you've deleted unnecessary files, reboot the device to see if it resolves the disk quota exceeded issue:
bash
reload
2. Resolving Read-Only File System (Filesystem Issues)
Since the request platform software package clean command is failing due to the file system being mounted as read-only, we need to resolve the read-only file system issue.
Step 1: Verify File System Mount Status
First, check if the file system is indeed read-only by running:
bash
show file systems
If you see something like Read-Only in the status, that confirms the issue.
Step 2: Remount the File System as Read-Write
In some cases, the file system might be mounted as read-only due to errors or file system corruption. Try remounting the bootflash file system as read-write.
Try to remount the file system:
bash
mount -o remount,rw bootflash:
After remounting, attempt the cleanup again:
bash
request platform software package clean
Step 3: Check for File System Errors
If remounting fails, the file system might be corrupted. You can try to repair it using the following command:
bash
fsck bootflash:
This will check for and repair any file system issues on the bootflash. After that, remount the file system and attempt the cleanup again.
Step 4: Reboot if Needed
If you're still unable to remount as read-write or the file system shows signs of corruption, you might need to reload the device and see if that resolves the issue:
bash
reload
3. Use "request" Commands for Cleanup (If File System is Writable)
Once you've cleared up space and resolved the read-only file system issue, you should be able to run the following command to clean up the package files:
bash
request platform software package clean
This will automatically clean up unnecessary software packages.
4. Consider Increasing Flash Storage (If Needed)
If you continue running into disk space issues, it may be worth considering upgrading the flash storage on your Cisco 4321 ISR.
Summary of Steps:
Clean up old files like old IOS images, logs, and backups.
Remount the file system as read-write if it's in read-only mode.
Run the cleanup command once you have space and the file system is writable.
Check for file system errors and repair them if necessary.
Reboot the device to ensure all changes are applied.
