Dumb question: why do you need a larger root filesystem?
First, how big is root? And if this is for stuff under, say, /var/www, I'd
make a separate logical drive/partition, and mount that, rsync everything
from /var/www to that, then shut down the web, and remount the new
filesystem on /var/www.
Root, itself, doesn't need to be huge. We're using 500G, and seriously
considering making it 125G in the future, with data, or web stuff, is on a
separate partition, so when there's a sudden explosion of data, / is safe.
