The Not enough space on device message is displayed when user attempts to copy to a Flash device, even after files have been deleted

Core issue

This problem is caused by a failure to issue the squeeze command after deleting the file on the Flash.

Resolution

After deleting files to free up space on a Catalyst switch with a Class A Flash file system, the squeeze operation must be performed to recover the space occupied by the files.

When a file is deleted by issuing the delete <device:> <filename> command, the specified file is marked as deleted, but continues to occupy the space on the Flash device.

To recover the space, issue the squeeze <device> command. This command permanently deletes any files on the device that have been marked as deleted. The squeeze operation may take a while, depending on which files are deleted and their position on the Flash device.

Note: If the device is an ATA FlashDisk, the squeeze operation does not apply.

The delete command permanently deletes the file on Flash disks.

This output is an example of deleting and squeezing a configuration file from bootflash:
