This occasionally happens to me when I've been editing an OOo document
that
resides on a flash drive I use with one of my laptops. I've
tried
poking around in ps to find out which process has the drive
locked, and I
can't figure it out. Nothing directly refers to the
flash drive except
one of the hald processes, and it's just scanning
the drive (I tried killing
that and it made no difference).
My usual sequence of events is as
follows:
1. Plug in the flash drive. 2. Wait for it to appear on the
desktop.
3. Start up a terminal window (which recognizes the flash drive
and
runs sudo to allow execute permissions on the drive). 4. Run the
script that unzips the files I want.
5. Open the file with the OO writer,
edit it for a while, then save
and close it. 6. Update the zip archive (on
the flash drive).
7. Close the terminal window. 8. Umount the drive, which
fails.
I've tried waiting for as much as five minutes, running sync
nothing. The last three times this happened, I had to shut down
the
laptop (which I was going to do anyway) in order to free the
flash
drive. This takes several minutes, which can be precious when I
need
to bag the laptop in a hurry.
There's nothing in any of the
syslogs. The laptop was just updates to
the L&G CentOS
5.5.
What am I
missing?
Thanks.

to me it sounds like the zip program is culprit since it might still holding onto the flash file system. did you try fuser -l on the flash drive and see what has a hold on it. just a thought.
