Begin t his procedure as the root user on the head node:
1. Change to the /var/lib/systemimager/scripts directory, and make a c opy
of the base_image.master.0 file:
# cd /var/lib/systemimager/scripts
# cp base_image.master.0 login.master.0
2. Use the text editor of your choice to open the new login.master.0 file, and search
for the block of text that looks like this:
BOOT_PERCENTAGE=".01"
ROOT_PERCENTAGE=".60"
VAR_PERCENTAGE=".39"
3. Increase the size of the /var file system to be 50% of the available disk space (after
accounting for sw ap space), and decrease the size of the / partition accordingly:
BOOT_PERCENTAGE=".01"
ROOT_PERCENTAGE=".49"
VAR_PERCENTAGE=".50"
4. Save y our changes to the file.
5. Identify the node names of the log in nodes:
# shownode servers lvs
n[135-136]
6. Create a sym bo lic link from th e node names of the login nodes to the n ewly-created m a ster
autoinstallation script. Note that the node name is appended with a .sh extensio n:
for i in n135 n136
do
ln -sf login.master.0 $i.sh
