After upgrading Huawei network equipment (routers, firewalls and switches), it prompts that there is insufficient space, how to solve it?

Recently I met a friend who said that he upgraded a certain Huawei router (the flash space of the low-end model is relatively small), and the file has been deleted. The file is indeed gone with dir, but the space has not been released. Upload the new system firmware. Still prompted insufficient space. There are generally two solutions to this problem.

Solution 1: When deleting a file, add /unrserved after delete. The /u parameter can be abbreviated and the file name can be abbreviated. /force means to delete without confirmation, and /f can be abbreviated so that the file is completely deleted and not put in the recycle bin

<Huawei> dir

<Huawei>delete /u ssl***.zip

Info: Deleting file flash:/ssl***.zip...

Deleting file permanently from flash will take a long time if needed...succeed.

Solution 2: Empty the lower recycle bin reset recycle-bin

<Huawei>reset recycle-bin

The external storage supported by Huawei routers generally include flash and SD cards, and the external storage supported by switches generally include flash and CF cards.
