Why do you have 777 on /usr? Try changing it back to 755 and see if you still get the error.

funny thing, ain't it?

check the permissions of the mountpoint (the /usr directory before the /usr filesystem is mounted). set it to 755.

very probably /usr will be busy right now, preventing a umount. so boot from dvd or the like in maintenance mode and choose "access rootvg" and mount the root FS someplace (/dev/hd4 is the lv with the / FS most likely) to examine the /usr mountpoint. alternatively you can work your way through /sbin/rc.boot, find the place where /usr gets mounted and put an ls -l or chmod before it and reboot. know what you're doing in any case or get someone who does to assist you.

Thanks Gann .. I will try your sugested rc.boot option tomorrow, that should be a clever way if it works ..

This may be a dumb point; but I assume that you mounted the usr filesystem on an existing /usr directory, acting as its mount point?

Could you post a "df -k" listing, to show it in position?

I just wish to confirm that it is mounted correctly, since you are unable to see the parent directory.

Tried to reply to this thread yesterday but for some reason, my post keeps getting flagged with "Disallowed content detected."
So, I'll try attaching this as a text file.

If the underlying directory that /usr is mounted from has bad permissions, this can actually be fixed without unmounting or rebooting.
The attached text document shows how.
