Hi, I would try the following to minimize the downtime

I will asume that the filesystem /Npbsunh2 corresponds for example to c5t6d0s4

0) Stop your non-global-zones (Start your maintenance window)
1) Umount Filesystem
2) Create a concat metadevice
metainit -f d51 1 1 /dev/rdsk/c5t6d0s4
3) Create a simple mirror
metainit d50 -m d51
4) Mount the filesystem but pointing to the mirrror metadevice
mount /dev/md/dsk/d50 /Npbsunh2
5) Start your non-global-zones (Here end your maintenance,window aprox 10 min)

6) Create new concat mirror to teh new disk/slice
metainit -f d52 1 1 /dev/rdsk/c10t0d0s1 (this is the new disk)
7) attach the second concat to the mirror
metattach d50 d52
8) monitoring the sync progress
9) when the sync is at 100% dettach the original disk
metadetach d50 d51
10) Now the filesystem live in the new disk

Notes:
Obviously you first need create the metadb slice if not exist
Later yo can grow the filesystem if is needed,

mdbFontSize(5)							 The m17n Library						    mdbFontSize(5)

NAME

       mdbFontSize - Font Size

DESCRIPTION

       In some case, a font contains incorrect information about its size (typically in the case of a hacked TrueType font), which results in a
       bad text layout when such a font is used in combination with the other fonts. To overcome this problem, the m17n library loads information
       about font-size adjustment from the m17n database by the tags <font, resize>. The data is loaded as a plist of this format.

       FONT-SIZE-ADJUSTMENT ::= PER-FONT *

       PER-FONT ::= '(' FONT-SPEC ADJUST-RATIO ')'

       FONT-SPEC ::=
	   '(' [ FOUNDRY FAMILY
	      [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
	    REGISTRY ')'

       ADJUST-RATIO ::= INTEGER

       FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
       See m17nFont for the meaning of each property.

       ADJUST-RATIO is an integer number specifying by percentage how much the font-size must be adjusted. For instance, this PER-FONT:

	   ((devanagari-cdac) 150)

       instructs the font handler of the m17n library to open a font of 1.5 times bigger than a requested size on opening a font whose registry is
       'devanagari-cdac'.
