I've got a usb HD mounted, and it has been mounted since the weekend, and
has been kept busy during that period.
now I"m done with it an want to umount it, but neither umount nor the
on-screen icon (when right-clicked) will let me do it:
it is /dev/sdd1, mounted as /media/seagateusb. when root tries to
umount it we get this:
# umount /media/seagateusb
umount: /media/seagateusb: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
lsof | grep sdd1 gives this:
$ lsof | grep sdd1
jbd2/sdd1 26358 root cwd DIR 253,1 4096 2
/
jbd2/sdd1 26358 root rtd DIR 253,1 4096 2
/
jbd2/sdd1 26358 root txt unknown
/proc/26358/exe
lsof | grep /media/seagateusb yields no output.
I know, I could reboot, but I'd just as soon not.
Anybody know what that jbd2/sdd1 stuff is that lsof shows me, or
how to umount it other than a reboot?
thanks!

You can open the GUI file manager, and do a safely remove/eject. Or you can stop autofs for a minute, and then umount it. mark
