I have a CMS disk mounted with cmsfs-fuse at /cms191.  It’s defined in the
directory as RR and mounted on Linux read-only.

>From my cms id I changed a file there, but Linux doesn’t see the change.

Based on that, I suspect the disk directory was copied to Linux memory when
the file system was mounted, so I have to unmount/mount it again.

To my surprise that did not work either.  I have to chccwdev -d 191 and
enable/mount again.

Is there a way to have Linux read the directory again without having to
take disk offline/online?

I have a bash script that uses the files on the 191 cms disk. I had code
that checks if /cms191 is a mount point, and if so, unmount/mount but
that’s not working.

This is rhel 9, but I see the same on rhel 7 (and don’t have a rhel 8
system)
