Description Jeff Layton 2011-08-05 14:14:52 UTC

I have a nfs mount:

salusa:/git/ mounted on /net/salusa/git with fstype nfs4 statvers=1.0
	opts:	rw,vers=4,rsize=1048576,wsize=1048576,namlen=255,acregmin=3,acregmax=60,acdirmin=30,acdirmax=60,hard,proto=tcp6,port=0,timeo=600,retrans=2,sec=sys,clientaddr=2001:470:8:d63:2e0:4dff:febf:6ba,minorversion=0,local_lock=none
	age:	4705

...(etc)...but when I run nfsiostat, it fails to find it:

$ nfsiostat
No NFS mount points were found

This problem also exists in f15, so it's probably been an issue for a little while.

$ rpm -q nfs-utils
nfs-utils-1.2.4-0.fc15.x86_64

I can replicate your results with an older version called iostat-ms.

Comment 3 Chuck Lever 2011-08-08 20:09:07 UTC

I cannot reproduce your results with the most recent version of nfs-iostat.py on Fedora 14; it works as expected when no argument is specified.  Maybe we don't have the a full reproducer yet.
