Ron Stone f125a8b892 Remove spurious escapes (r8,dsR8) 
This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

Increase the Size of a Partition

You can increase the size of a partition using the system host-disk-partition-modify command.

You can modify only the last partition on a disk (indicated by part in the device path; for example, /dev/disk/by-path/pci-0000:00:0d.0-ata-2.0-part6).

You cannot decrease the size of a partition.

The syntax for the command is:

system host-disk-partition-modify -s <size> <host> <partition>

where:

<size>

is the new partition size in MiB.

<host>

is the host name or ID.

<partition>

is the partition device path or UUID.

#. For example, to change the size of a partition on compute-1 to 726 MiB, do

the following:

~(keystone_admin)]$ system host-disk-partition-modify -s 726 compute-1 a259e898-6390-44ba-a750-e0cb1579d8e0
