strace of mount after using nautilus
This is an strace of "mount /dev/fd0" after using nautilus to mount and umount
a floppy disk. I don't know why, but the mount doesn't succeed when doing the
strace. The strace does have some "invalid argument" errors in it though.
Yuk. An obscure bug that sounds real & reproducible. Alex, any ideas from the nautilus side? Wow. bizarre bug. The reason it fails under strace is (i think) that the whole setuid thing doesn't work for straced processes. You'd have to test it as root with strace (but then the problem goes away!). Upfront i have no idea what is causing it. It needs some further study. Sighted with FC3 devel tree. What happens is that mount tries to guess the fstype, but it's a bad floppy so you see that I/O error message. However, the mount itself still succeeds. The problem happens for me with both 'mount /dev/fd0' and 'mount /mnt/floppy' - I'm guessing in your case it was just the timing of commands rather than the exact command line itself. Anyways, use a good floppy and the problem goes away. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: Bear with me this is complicated :) This bug might need to be assigned to nautilus, because this only seems to happen after nautilus tries to mount the floppy from the gui. Mounting a floppy, the first time after inserting it into the drive, using the device name, gives the error message /dev/fd0: Invalid argument (The mount succeeds, however) This always happens the first time when using nautilus. On the command line, this only happens when: - Nautilus was last used to try to mount the floppy. AND - Its the first time after inserting the disk. AND - I use the device name, not the mount point, as the option to mount. mount /dev/fd0 <- This raises an error mount /mnt/floppy <- This does not raise an error After the initial error, you can mount and umount to your heart's content with no errors. This does not happen as root. Things that make it go away (on the command line) 1) mount and umount the floppy 2) umount the floppy when the floppy is not mounted, but after nautilus was the last program to try to mount the floppy. To make it happen again, just right-click on the gui desktop and choose disks->floppy from the menu.
