On beta cluster we are making use of role::labs::lvm::mnt to allocate the
instance disk space to /mnt .
I created a new Trusty instance deployment-cxserver02.eqiad.wmflabs which has a
puppet failure:

Skipping because of failed dependencies
Using parted on /dev/vda there is still 42GB of free space:
# /sbin/parted /dev/vda print free
Model: Virtio Block Device (virtblk)
Disk /dev/vda: 42.9GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
1 32.3kB 8191MB 8191MB primary ext4
> 8191MB 8191MB 476kB Free Space
2 8191MB 10.2GB 2048MB primary ext4
3 10.2GB 12.3GB 2048MB primary ext4
4 12.3GB 14.3GB 2048MB primary linux-swap(v1)
> 14.3GB 42.9GB 28.6GB Free Space
Could it be an issue in make-instance-vg? It invokes:
/sbin/parted /dev/vda print free|fgrep 'Free Space'|tail -n 1|sed -e 's/ */
/g'|cut -d ' ' -f 2,3
Which returns:
14.3GB 42.9GB
And thus invoke:
/sbin/parted -s /dev/vda mkpart primary 14.3GB 42.9GB
The bug prevent us from finalizing the creation of
deployment-cxserver02.eqiad.wmflabs which is the content translation server on
the beta cluster (bug 71783).
