by I seem to be having a weird sporradic problem with umount. I am
running Linux 0.99PL12 release SLS1.03 on my 486DX/33. When I mount a
drive - whether it be another harddisk/partition or a floppy - umount
sometimes refuses to let me unmount it, responding with the above
error. I have to reboot to clear it, and the reboot program notes
that it can't unmount the drive either, but reboots anyway. (Is that
safe?) When the system comes back up, the drive is unmounted.
The man pages say that the error is caused by some process using the
files under the mount point or having a wd under the mount point, but
I don't know what processes would be under /mnt (where I typically
mount stuff).
Since it doesn't happen all the time, it's not easy to trace. Can
someone tell me what's a good way to determine the wd of a process?
Is there anything other than the process-under-mount-point thing that
could be causing the umount problem? Any help, answers, or
suggestions would be appreciated!
