Hi,

You can try to log in from console, but from single user mode. If you are able to login, remove unnecessary files from /dev/root

Hi,

As per above if you can enter the system and zip some files especially the versioned .conf files under /etc/lvmconf i suppose your problem might be solved.

You say you put them on via NFS. Were you logged in to a different system to do this? If so, it might be worth trying to remove them (or move them to a different filesystem) while logged in to the different system. That would save you from having to bring the server down.

Hi Amit,
If you can login through ftp then loggin to the server and try to delete big file from /
using del command from ftp
after deleting files then try to login the server

check if any huge file is in the /dev directory. it is quite common for accidental wrong input when writing to a device file which instead got written into incorrect device filename causing the root filesystem full.

Hi Amit,

Reboot the server and login through single user mode.

If you start the system to single-user mode, you don't have to log in. The system opens a shell as root automatically.

An alternative can be to use the HP-UX Recovery CD and mount the root filesystem as regular filesystem as soon as the system has booted. Find at least 1 big logfile that you don't need anymore and reboot again (to single-user mode or run-level 1). Log in again and further cleanup /dev/root

Amit,

if your / is full, you can use

#find / -xdev -size +2000 > /tmp/out

check /tmp/out see got any big files ?

hope this help
