[openstack-dev] [Infra] Question about disk partition

I am investigating a gate failure(#1).
On some sample(#2), "create server" continued to fail due to "No space left on device".
Is it possible to extend the root partition?

On the above sample, the fisrt IOError happened when writing a tempfile under /var/cache/nova directory:
 File "/opt/stack/new/python-keystoneclient/keystoneclient/middleware/auth_token.py", line 1337, in token_revocation_list
 IOError: [Errno 28] No space left on device

According to some df.txt.gz's of successful samples[#3], the root partition seems small:
 Filesystem      Size  Used Avail Use% Mounted on
 /dev/vda1       9.9G  8.4G  1.1G  90% /
 udev            3.9G   12K  3.9G   1% /dev
 tmpfs           1.6G  384K  1.6G   1% /run
 none            5.0M     0  5.0M   0% /run/lock
 none            3.9G  4.0K  3.9G   1% /run/shm
 /dev/vdb2       219G  8.1G  200G   4% /opt
 cgroup          3.9G     0  3.9G   0% /sys/fs/cgroup
 /dev/loop0      6.0G   68M  6.0G   2% /opt/stack/data/swift/drives/sdb1

I am not familiar with the gate test environment,
so I'd like to know whether the above approach is right or not.
