nfs mount debug
Hello all
We're testing data migration from VNX/file to unity and I've got a problem mounting nfs (v3) from unity to ibm iseries (as400). If we try to mount the same mount on linux it works w/o problem.
How can I debug nfs mount on unity? Where I can find nfs mount log (on vnx server_log server_2 -f )
thanks
Matteo

Hi Rainer
iseries can mount nfs v2,3,4 I've tried all protocol version.
How can I use tcpdump on a interface not listed in ifconfig? On linux I use tcpdump -i ethX, In my configuration nas server has got if_10, if I try to tcpdump -i if_10 _i receive operation not permitted
thanks
Matteo

On Unity there is a svc_tcpdump command for this
see the Unity service commands manual for details - also see kb489350
please be careful where to write the data - do NOT fill up /tmp - it will cause problems

you can get the various log file through a data collect
I doubt though that there is much in there for mount
I would suggest to take a tcpdump - there it should become apparent why it didnt work
most likely is that your export statement isnt correct
are you sure that the ibm can do nfs over tcp ?
