Hi
I'm using HP-UX 11.00, the root file system is as shown below. Several time it reach 100% used, to free some space I use to reboot the system. What can I do to free some space without rebooting the machine?

Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 143360 44963 92443 33% /

Thats a pretty general question...could be many things. In general your root mount point will should stay the same size and not grow. It is possible that your /var or is not on a separate mount point as it should be.

Post your output of bdf showing all mount points under vg00...

If you dont see a /var separately, then that could be it.


Also, before you reboot again... do a find for large files. Here is a handy script one of my friends wrote.

# bigfiles / 10000000

# bigfiles requires 2 parameters...
1) the first is the beginning directory
2) the second is the size of the file to search for
------------------------- cut here --------------------------------------
# cat bigfiles
# To find any file over a certain size in a given directory
# Primarily used to locate files which might be running a filesystem out of
# space.
#
# First parameter is the filesystem or directory to begin the search from
# Second parameter is the size of the file, in characters, to find
#
#
if [ $# -eq 2 ]
then
if [ -d $1 ]
then
#ls -l `find "${1}" -xdev -size +"${2}"c -print`
find "${1}" -xdev -size +"${2}"c -print > /tmp/crslist$$
if [ -s /tmp/crslist$$ ]
then
ls -l `cat /tmp/crslist$$`
else
echo "apparently no files that large in "${1}
exit
fi
else
echo "$1 is not a directory...try again"
exit
fi
else
echo "\n\nbigfiles requires 2 parameters..."
echo "\tthe first is the beginning directory"
echo "\tthe second is the size of the file to search for\n\n"
fi

------------------------- cut here --------------------------------------

Hi

Basically you can't increase the size of root lv.
You can use ignite ux's make_tape_recovery utility or you can backed up system then fresh install and restore

I hope this helps
