HPUX 11.31 root cannot touch directory.

[LITWINCZUK]

I have strange situation... OS: HP-UX 11.31 ia64

root user cannot touch one of directories. I see "Permision denied"..

Can anyone explain it to me?

You have mounted a directory from another server.
At this server root from your server has no permissions!
You have to give permissions at hostc (normally in /etc/exports).

Thanks.

BTW: how to permamenty delete this share?

server is rebootet one month ago, /etc/auto.direct is dated before this time, 27 Apr.

Hi,

check in /etc/fstab for mount point and execute command umount -f

Thanks

there are no entries about /u03 in /etc/fstab..

but... 

#mount
/u03 on /etc/auto.direct ignore,direct,dev=4000003 on Wed Jun 1 05:57:42 2011

It's mounted on /etc/auto.direct so it's from an automouter configuration ....
Maybe in an init directory (/sbin/rc1.d or rc2.d, ...)

[V. Nyga]

Found it (at least in 11.11):
set "AUTOMOUNT=0" in /etc/rc.config.d/nfsconf

>set "AUTOMOUNT=0"

Do you really want to turn the automounter off completely or just the one filesystem?
