Cannot run ls on the root directory

[tinker123@gmail.com]

CentOS 7.6.180
GNOME-CLASSIC 3.28.2

I've always been able to run ls on the / directory in the system above.

Now it just hangs when I run ls. Same if I try to see the / dir with software other than the terminal.

However, I can successfully run ls on the / dir is I use sudo.

Using sudo does not work if I try to ls -l

This change happened after I cancelled a large rsync job in the / dir ( ctrl c ) and issued a reboot -f command.

I don't know if those things are the cause.

How can I restore the ability to read the / directory with ls?

Are all file systems mounted? - I've seen similar problems when they're not.
And you may want to run yum update to get 7.8 (and if you enable the CR repo you will get 7.9).

The problem solved itself.

I connected back to that computer this morning.

The problem was gone.

My theory is that the "cancelled" rsync still had something running, something was blocking ls from operating on /

Thanks much for responding.
