From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20020830 Description of problem: mount -o remount ro /mount_point then command completes with no error but when you do a mount listing the /mount_point is still rw you can mount the file_sytem ro and change to rw but once it the files system is read write it can't be remounted read only. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. mount any file system rw * fstab entry /dev/Volume02/fileserver03 /file_server ext3 defaults 1 2 [root@trinity root]#mount /file_server 2. try to remount the file sytem ro root@trinity root]#mount -o remount ro /file_server 3. display [root@trinity root]#mount /dev/Volume02/fileserver03 on /file_server type ext3 (rw) Actual Results: root@trinity root]# mount -o remount ro /file_server/ [root@trinity root]# echo $? 0 root@trinity root]# mount /dev/Volume02/fileserver03 on /file_server type ext3 (rw) Expected Results: /dev/Volume02/fileserver03 on /file_server type ext3 (ro) Additional info:
Your instructions had a space in between "remount" and "ro" - if that's really what you typed to reproduce the problem, that's incorrect, and you need to use a comma instead to separate the "remount" and "ro" options. When using a space, I can reproduce your problem. Using a comma, everything works fine.
