Need to unmount a nfs file system
Hi Gurus,
I have an NFS mount issue in my server.
Due to some issue its not getting available in my server and I want to remount it.
root@server11:.../root # grep -i "filerx" /etc/mnttab
filerx:/pl_dvise_totransfert /local/home/DVISE_AEROLIA-TRANSFERT nfs rsize=32768,wsize=32768,proto=udp,NFSv3,dev=6800000c 0 0 1288497653
root@server11:.../root #
while trying to unmount getting errors:
root@server11:.../root # umount /local/home/DVISE_AEROLIA-TRANSFERT
nfs umount: nfs_unmount: /local/home/DVISE_AEROLIA-TRANSFERT: is busy
umount: return error 1.
root@server11:.../root # umount -f /local/home/DVISE_AEROLIA-TRANSFERT
umount: illegal option -- f
usage: umount [-V] [-v] { special | directory }
umount [-F FStype] [-v] [-h host] -a
root@server11:.../root # uname -a
HP-UX server11 B.11.11 U 9000/785 2002865316 unlimited-user license
Seems umount is not help full here?
Any option in 11.11 to unmount force fully [ other than reboot? ].
Cheers
Sree

You need to use fuser(1m) to find who is using that filesystem and get them off. Anyone's CWD there?

I think you need to be on 11.31. But fuser(1m) may find the users that cause it to be busy.
