When the file system has been mounted, it is possible to unmount it using the umount command (without an *). How Do I Unmount And Remove Filesystem In Linux? Credit:
WIPEFS EXAMPLE HOW TO
xfs_growfs can be used to grow it further if you need to (see section 6 for more information on how to use xfs_growfs). Wipefs -a must be set up if erasing is to occur. The rmfs command can be used to delete old file systems from a computer. For example, to force unmount the /dev/sdb1 file system, type the following command:
If the file system is in use, you may need to use the -l flag to force unmount it. For example, to unmount the /dev/sdb1 file system, type the following command: To unmount a file system, use the umount command. +Restores an ext2 signature from the backup file ~/ file systems in Linux can be unmounted via the command line.
