Hello,
I have been experiencing this problem since a little while, so I
thought I'd make a bug report.
If I use emelfm2 plugin to mount devices, everythings's fine. However,
if I do any writing on the device using e2 (like copying a file), then
emelfm2 won't unmount the device, stating it's busy. Manually
trying to unmount the device in a terminal will fail as well.
Probing the device with lsof:
# /usr/sbin/lsof | grep "SD128"
emelfm2 3928 thk cwd DIR 8,33 16384 86 /media/SD128/Media/Documents
In that case, SD128 is the mountpoint, Documents is the folder where I
copied a file.
This issue only appears when following a writing operation. A reading
operation only (like opening a file to view its content without
modification) doesn't cause any trouble.
And if I open a terminal to manually do the writing operation (i.e. cp
~/test.pdf /media/SD128/Media/Documents), then unmount will be
successful. The "bug" arises only if emelfm2 did the writing operation.
It seems emelfm2 leaves a process unused in the mountpoint, which
prevents the unmounting.
