dtrace discuss - Apr 2009 - unable to find any probes from the nfs provider

I want to list/use the nfs probes but I get the error "dtrace: failed to 
match nfs*:::: No probe matches description". Is there a way to enable 
nfs provider probes? My system is running snv_112 (bfu''ed from the gate
archive)

# dtrace -lP nfs*
   ID   PROVIDER            MODULE                          FUNCTION NAME
dtrace: failed to match nfs*:::: No probe matches description

thanks

Are you exporting any file systems?  I don''t see any nfs probes until
I explicitly share something.

dtrace -l -P ''nfs*'' will get you the nfsv3 and nfsv4 providers
assuming
you''ve
done something to load nfs. Without the single quotes, I see the same 
message
as reported. With the quotes, I see data.

Sorry. Single quotes make no difference. It goes back to whether nfs is 
even loaded.

modinfo | egrep nfs to see.

2 hours of sleep is not enough,

thanks for all the responses. After exporting fs, I can now see the 
probes from the nfs provider.
# share
-               /share_nfs   rw   ""
#
# modinfo | egrep nfssrv
290 fffffffff7fcc000  47328   -   1  nfssrv (NFS server module)
#

thanks
