Subject: Re: mounts cd twice
Hi Mike,

It's worth noting that fstab is the list of available filesystems and mtab is the list of currently mounted filesystems. In other words fstab says nothing about the current state of mounts, but rather is a list of mounts you've defined to be available. You can run the command `mount` to see what is currently mounted. Also keep in mind that the error "location already mounted" means the location you're mounting, not the device you're mounting, I believe someone suggest `umount /dev/cdrom` this assumes that the device already mounted is the cd (which is not necessarily the case, more likely whatever service that auto mounts wants to use a directory that's not empty, like `/media`. I'm not a desktop Linux user, so I don't know where the dir it tries to mount to is but worst case scenario you could run: 

    mkdir /media/mynewdvd
    mount /dev/dvd /media/mynewdvd


As root and sidestep the auto mounter.

Subject: Re: mounts cd twice

I don't understand... the cdrom isn't mounted until I put a disk in. so why is it saying that it is already mounted? In fstab everything that is mounted is a hard drive, not the cdrom. Please, I don't want to upset anyone, I want to understand.

The HD partitions are what is already mounted. The automounter trying to mount the now present media in the CDROM drive is telling you it won't auto mount there because doing so would make what is already mounted there inaccessible. When you click on OK, you are telling the automounter you accept the consequences.

The cd isn't mounted unless I put a disk into it and after I put a disk in a info window appears saying that 'Location is already mounted.' So please, tell me, how is changing the mount points of the hd partitions going to fix the cdrom mount?

Mike, your initial complaint was a message that said something was already mounted there. The result of you running the mount command showed you what that was. And the first paragraph of the man page says that if you go ahead and mount something there any WS at that what was there before becomes inn accessible and that permissions for the directory get changed as well.

So your entire question has been answered and the way to fix it is clear. Change your mount point for those partitions and all will be golden. What could possibly still be your question?

yes... I do have things in media. but they are all partitions, not the dvd.

So this clearly shows that you DO have things mounted on /media. Specifically the bmike1 base which was your experiment to move your data files elsewhere. Mike, read the first paragraph of prose in the man page on mount.

I’m sorry, I haven’t been watching this thread very closely - did anybody ask about doing ‘mount’ to see what it thinks is mounted?
