some more info

geom knows about the md dev

Geom name: md2506
Providers:
1. Name: md2506
    Mediasize: 1392508928 (1.3G)
    Sectorsize: 512
    Mode: r0w0e0


Actually, the one I did earlier today did not work either.  I did it  
as part of a script and did not notice the error message, which is  
the same...

Is there a limit to the number of /dev/md devices I can have?   I  
have 106, 2 of which are not working with this bsdlabel problem.  I  
read the man pages for md and mdconfig and did not see any limits  
listed.

Thanks in advance for any help on this.

best
Chad
