Thanks Henrik,

I used a shorter name. It now creates the rrd files with the quotes.
I'm not thrilled about the quotes, but it is working.
-rw-r--r--   1 bb users 190408 Apr 22 10:19 netappvolume.",vol,testvol,".rrd
-rw-r--r--   1 bb users 190408 Apr 22 10:14
netappvolume.",vol,testvol,.snapshot".rrd

In hobbitgraph.cfg I was able to exclude the quotes from displaying in
the graphs. It looks much better that way.
[netappvolume]
        FNPATTERN ^netappvolume.\"(.*)\".rrd

Yes, looking at the mib it's a DisplayString/octet string. I have not
found an explanation for the quoting.
        DfEntry ::=
            SEQUENCE {
                dfIndex
                    INTEGER,
                dfFileSys
                    DisplayString,

Some of the volume names are ending in "/..". I asked one of a our
storage guys to look at it. I am starting to think it might have to do
with an option on the snapshot volumes.
["/vol/pcluns/.."]
	dfIndex = 14
	dfMountedOn = "/vol/pcluns/.."
["/vol/pcluns/"]
	dfIndex = 13
	dfMountedOn = "/vol/pcluns/"
