famd disallowing umount /mnt/camera

blaksaga

Back in the day I used to have a problem where often I couldn't umount /mnt/cdrom because fam was accessing it causing "device is busy." Since then the devs have fixed that little problem.

Now, however, I am getting the same thing with my digital camera.

Is there any way to stop fam from fucking with /mnt/camera? Or do I have to always kill fam, umount, and start fam again? Or should I just say "fuck it" and unmerge fam completely because it's caused me a lot of headaches in the past and is continuing to do so?

have you tried doing a lazy unmount? it works for me when lvm doesn't let me unmount a volume group.

I get the same problem.. Also with my CDROM..
How do you stop that ugly beast from locking files on removable media?

I get the same problem with a FAT partition on my other hard drive. Interestingly, it only gets locked when I access it with nautilus. If I only access it from command line, fam won't lock it.

My workaround is restarting the fam deamon:
/etc/init.d/famd restart
umount /mnt/shared

I don't like to use umount -l, because it only detaches the filesystem from the hierarchy, but doesn't clean up references to it until it's not busy. But if fam keeps it indefinitely (my experience is this) then the references will never be cleaned, i. e. the filesystem won't be properly unmounted. Tell me if I'm wrong.

You can get used to it, but it's definitely annoying.

Make sure that nautilus is not browsing the directory that you are trying to unmount. As long as I have no applications using the mounted device I have no problems with fam anymore.

Hmmm...well...all I can suggest is seeing if there is an updated fam and maybe file a bug report.

I am using

app-admin/fam-2.7.0-r2

and am experiencing no problems. I used to have the same problem but I updated fam a while back and has worked since. Sorry, don't know what else to tell you.

I'm getting this exact same problem, too - famd locks up my FireWire hard drive.

I use csab's workaround

This is a known issue with famd. Sun knows about this. (They are the creators and maintainers of famd.) Due to the nature of famd there is no possible
solution to this issue. It will remain for good. This is was famd is depreciated in favor of it's newer and better replacement called "gamin".

Yeah, that's what I'm using now. Famd was OK in Gnome, but a little while ago I switched to KDE, and it went mad! For the entire time I was logged in, it was constantly accessing the disk and eating all the CPU cycles. Gamin doesn't do that. I prefer Gamin

I'm so happy to have found this thread! It was really getting under my skin that fam would not play nice. With gamin devices will cleanly unmount even with a instance of nautilus displaying them. It worked flawlessly when I tested things with my cdrom, camra, and mp3 player.

Yup - it's a good thread
