I'm having a problem with a file system to unmount.
There is a inconsistency, bdf sees it different than what is in the mnttab.
Is there a save way to clean this up ?
root@luxtc1:/> bdf /huu10
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 1048576 106496 934920 10% /
root@luxtc1:/> grep huu10 /etc/mnttab
/dev/vg52/lvol2 /huu10 vxfs log,nodatainlog 0 0 1088174817
root@luxtc1:/> mount |grep huu10
/huu10 on /dev/vg52/lvol2 log,nodatainlog on Fri Jun 25 16:46:57 2004
root@luxtc1:/> bdf |grep huu10
/dev/vg52/lvol2 1048576 106496 934920 10% /huu10
root@luxtc1:/> umount /huu10
umount: cannot unmount /huu10 : Block device required
root@luxtc1:/>
Thanks
Matthias

Re: umount Block device required
check to see whether any file(s) in the filesystem is open??? use lsof utility.
if not installed get it from

Re: umount Block device required
Looking through the output of lsof, there a lot of processes, shell and system processes pointing to the mount point in question /huu10.
What can I do ?
Do I need to reboot the machine ?

Re: umount Block device required
Can I remove just the entry for /huu10 in it, or is it saver to remove the complete mnttab and regenerate it with mount ?

Re: umount Block device required
No you can not remove the mountpoint from the mnttab.
# mv /etc/mnttab /etc/mnttab.old
# mount
