I am finding difficulty in creating and allocating correct size to File Systems on solarix x86 box. Please see below contents I followed on screen and in the end It shows that /app file system is created of size 135GB , I wanted it to be 30gb as mentioned during 'format' command in 'Enter Partitiion size' :
