You can't unmount it, because it's being used. From the error message, /dev/sda1 is the location of your root directory / . Instead, create a gparted live CD, then boot from that. Then, you should be able to resize the (now-unused) root partition.

Unmounting the SD card does NOT result in a loss of data or anything saved on your SD card. It simply tells the phone to stop showing things from the memory card.
"Unmounting" means the OS gives up control of the SD card so that other processes, like copying files to your PC and back can access the SD card. I know it sounds a bit archaic for such a "modern" OS. Even my much maligned Windows Mobile phone I had before didn't require this mount/unmount business.

Steps to recover data from a corrupted SD card using Disk Drill: Download and install Disk Drill. Connect the SD card to your computer either by attaching the device that contains the card or using a card reader. Click the Recover button to perform the actual corrupted SD card recovery.
This NFS Stale File Handle error occurs due to following reasons: A file handle becomes stale when the file or directory referenced by the handle is removed by another host/server, while our client still holds an active reference to the object file/directory.
Stale files are usually found using ls -ltR /<mounted directory path> | grep "?" , but this usually takes some time (since it goes over all files in a given path). To further clarify, the issue seen in specific files such as Java library file(s) rather than the whole mount.
So, in order to remove the file completely we must must kill that process which is currently using it. You can list down these files by running ' ls -lah ' command from nfs share mounted directory, the process needs to be killed which has open these files in order to release space .
Port 111 (TCP and UDP) and 2049 (TCP and UDP) for the NFS server. There are also ports for Cluster and client status (Port 1110 TCP for the former, and 1110 UDP for the latter) as well as a port for the NFS lock manager (Port 4045 TCP and UDP).
The mount command mounts a storage device or filesystem, making it accessible and attaching it to an existing directory structure. The umount command "unmounts" a mounted filesystem, informing the system to complete any pending read or write operations, and safely detaching it.
So, in order to remove the file completely we must must kill that process which is currently using it. You can list down these files by running ' ls -lah ' command from nfs share mounted directory, the process needs to be killed which has open these files in order to release space .
