[opensuse] Problem with mount via device notifier
When I mount a USB stick via the device notifier, I can't edit or change attributes of any file. I seem to own the file and directory and have owner write permission, according to LS. Not only can I not modify the file, but I can't chmod or chow/chgrp it as root either. The entry in the mount table reads /dev/sdb1 on /media/STORIES type vfat (rw,nosuid,nodev,uid=501,utf8,shortname=mixed,flush) Do I need some kind of magic in fstab or some hal entry? -- Vizzini: INCONCEIVABLE!

Mounting one of my Thumb drives (a patriot 16gig) I see the following: /dev/sdb1 /media/PATRIOT vfat rw,nosuid,nodev,uid=1000,utf8,shortname=mixed,flush 0 0 which looks like yours other than the uid. For any recent version of opensuse uids tend to start at 1000, so unless you migrated this system from the Pleistocene that might be a tad suspect. Just gotta ask: Are you sure there is no physical switch on this device for write protection that you forgot about? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I guess it is the output from running the "mount" command without parameters. It always formats things like that Anders -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I took him at his word that it was from his mount table and leaped to the conclusion he meant /etc/mtab or /proc/mounts I've just never seen parens in either of those places. Further, he mounted via the Device Notifier, not a command line. Very odd. -- Explain again the part about rm -rf / -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That's the output of the 'mount' command.

It is vfat. The vfat file system has no concept of owner of file permissions, so it is not surprising that you can't set them. This is why the ownership of the files on the partition is set with a mount option The vfat file system also doesn't support any other kinds of attributes. If that is important to you, you need to reformat your USB stick with a better file system Anders -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

But he also said "Not only can I not modify the file" which I took to mean he could not write to the files. Maybe I attributed too much meaning to a casual phrase. -- Explain again the part about rm -rf / -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Perhaps. Anton will need to clarify. I understood it to be about file attributes, ownership and permissions, not about the files themselves. If it is, then something deeper is wrong.

As in "something deeper is wrong" when one can't edit a file and write it back.

Granted, but that doesn't address the real issue. I'm trying to edit the file. I can't; it won't let me save. I can't write back to the device. I can't see any reason why I can't write back to the device.

In that case I guess John's suggestion that you look for a write protection switch on that stick is the best. Apart from that, I can't think of anything Anders -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
