in single user mode..

when i try to unmount the /usr FS i cant unmount it.


i tried with umount -f /usr but hp-ux 11i v1 not supporting forcefully unmounting options..

tried with fuser -cu /usr ,,, and fuser -kc /usr

how can i unmount it

Check with lsof which process use that mount point:

lsof | grep usr

how did you _get_ into single user mode? The only _supported_ way is to reboot and then interrupt the boot process and launch the boot loader with the "-is" option - methinks you didn't do this if /usr is mounted.

What do you want to do?

You should try to boot into maintenance mode (parameter "-lm").
