vx_nospace - /dev/root file system full (1 block extent)

[VMG]

Hi everybody!

As you can see, we have some problems with a server...
There's no way of login from the console, neither the lan console neither remotely with the command remsh {server} /usr/bin/ksh -i that was recomended in another message.
Any idea will be really wellcomed!!!

Hi,

I don't think you can use any of the tools to get in unless you already have a window opened.

You will need to reboot the server to single-user mode and fix the problem. YOu will have to hardreset the box either through GSP/Console and do a 'rs' or turn the ker off/on or turn off/on the power switch depending on your system.

Interact with isl at the bootadmin. Get into single user mode

isl> hpux -is

Once you are in single user mode mount /usr, /var and /tmp

#mount /usr
#mount /var
#mount /tmp

#du -xk |sort -n|tail

Look at the directories|files that are culprits. It may be that one of your device files (like /dev/rmt/0m) might have become a regular file or there is a big coredump by one of the processes.

Once you're back up, it would be useful to understand how it happened in the first place, then prevent it in the future (or you'll be doing this again).

In addition to previous comments, you can also look for log files or mistakes made by someone with root privs (accidentally copying a file to the wrong place).

Hi,

mic is right on.
You need to determine just *what* filled /
Usually it's someone mistyping /dev/rmt/0mn or /dev/dsk/cXtYdZ or such & then this becomes a user education issue. Ain't life as a SA grand?

While I realise this should now have been solved, one thing that may have worked would be to try to ftp to the box and delete the offending file.

I can remember using ftp in the past to get out of a sticky situation where I couldn't login on the console, or from telnet (Can't remember exactly what the problem was though)...

Tony.

Handy root fs check script

du -kx / | sort -rn

Helps you hunt down those files.

Any file copied into a filder like /var while unmounted becomes hidden after mount. This space is used on the root filesystem.
