[StarCluster] starcluster resizevolume fails

[Ryan Golhar]

I have a 20GB EBS that I'm trying to resize to 200GB.  I used resizevolume
but got an error:

[ec2-user at awsmicro ~]$ starcluster resizevolume vol-6109f51c 200

It turns out, e2fsck needs to be run first:

root at ip-10-158-10-170:~# resize2fs /dev/xvdz
resize2fs 1.41.14 (22-Dec-2010)
Please run 'e2fsck -f /dev/xvdz' first.

root at ip-10-158-10-170:~# e2fsck -f /dev/xvdz
e2fsck 1.41.14 (22-Dec-2010)
/dev/xvdz: recovering journal
