His guys it is well known that when mounting a file system, a number of options may be supplied, such as enabling read-only or read-write access to the data on the mounted file system. However I have a newly-created ext4 file system already mounted in my directory hierarchy. Currently, I am required to remount the already mounted file system, providing only read access to its contents.
I used the following command with the sdb1 already mounted to ext4 file system. Currently I am about to remount it to the Sales directory in a "read only" option.
When I entered the command line , the option of or read only didn't work. It remained in its default which was read and write (rw).
Can someone help me please.
