Linux quickly expands disk extra space to a mount point

Because before the user was created, the space allocated for the user only 5 G, in the subsequent development, storage more and more, the space is not enough, look at the Internet, a lot of it is to teach us to assign the rest of the load point to allocate too much space allocated to the space shortage of the mount point, the steps are not too complicated, mainly to implement After resize2fs , the error will be:

inch  while trying to open/dev/rhel/root

Check the solution, but found too complex, too lazy to toss. Then re-find the expansion plan, found the following command:

sudo xfs_growfs/dev/rhel/root

That is, the xfs_growfs instruction will automatically expand the/dev/rhel/root to the maximum usable size of the system.
