A few days ago one of my Solaris box’s filesystem got full of space so I was unable to get the system working properly and I was unable to boot it. This tip will show you how I got rid of this issue.
First of all insert the Solaris installation CD-ROM and boot your machine. Then press STOP-a and type the following in the prompt:
boot cdrom -s
After a few minutes you’ll get a prompt where you could start your job. In my case I did the following to free some space:
mount /dev/c0t0d0s0 /mount_point
find /mount_point -size +1000000 | sort -nr | more
Once you’ve done…
reboot
Note that this tip is also valid in other circumstances where you are unable to boot your system.
