I am getting the following "Invalid DS name" error in rrd-status.log

just had a thought. Is it the quotes need to be stripped out or
converted?

 The quotes look odd, but that is not the "Invalid DS name" problem.
 This is caused by your dataset names being excessively long. E.g. you
 have a "dfPerCentKBytesCapacity" dataset - this is 24 letters, but
 RRDtool limits names to 19 characters.

["/vol/testvol/"]
      dfIndex = 17
      dfMountedOn = "/vol/testvol/"

 Yikes ... the MIB probably has this defined as an "octet string", so
 why bother quoting it ?

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/"
