You have several problems here.

You need to increase nfile kernel parameter and maybe several others too. You will need to reboot.

Your filesystem is fragmented.

And you most likely have /dev/vg00/lvol3 mounted as /dev/root.

If /dev/vg00/lvol3 is mounted as /dev/root as per bdf output, then rm /etc/mnttab, then mount -a

To fix the fragmented filesystem, delete any unwanted files. Otherwise take an Ignite backup and restore the system from the Ignite tape

Monitor your system to determine if other kernel parameters need changing.

Tim.

Hi,

1.Kernel parameter nfile has to be increased for first error message( Maximum number of file opened system wise)
2.Your root file system is full. so delete some unwanted files.

Hi,

some running process keeping it's logs in /.

If u have glanceplus run /opt/perf/bin/gpm and look for process(s) utilized 80% and above, stop those processes.

ifu don't have glanceplus
#ps -aefx
will list all processes, look for processes which are consuming more time, and stop those processes

Filling / usually comes from a poor backup or core files.

Check that there is not a standard file called /dev/rmt/.... that takes up lots of room. The easiest way is:

# cd /dev
# du -sk *

You'll probably find it there.

to fix the /dev/root mounted on /

# mv /etc/mnttab /etc/mnttab.old
# mount -a

Things to look at:
bdf

and see what is mounted on /

Where can you can space:

- /var/opt/omni/log (if there is OB)
- /dev/rmt (if someone used a wrong device)
- /var/adm/syslog/*.log (if they grew much)
- issue a "cleanup -c 2" to remove superceded patches
- find / -xdev -size +5000000c
- find / -name core
- /tmp (delete it all!)
Massimo

for the nfile: you must rebuild your kernel, but ONLY after having fixed the / full

- /var/adm/crash
