Hello,

I am tunning my NFS configuration on a RedHat ES v3 (equivalent Fedora 
Core 1 , kernel 2.4.X)  and by reading the docs (NFS howto perf 5.6 )  I 
should see if I have enough NFSD daemon by looking at  
/proc/net/rpc/nfs, especialy line "th"

$ grep th /proc/net/rpc/nfsd
th 8 41598 20357.020 3974.540 1809.300 0.000 998.210 781.650 483.840 
116.640 0.000 825.230

However I cannot understand how to read that information !?
I see that I have 8 threads (8 nfsd daemon runing) but figures after ???

Second question,

How on an NFS client (Here I have fedora core 2 clients) can I see how 
is currently mounted an NFS filsystem, I want to check what are the 
current options in use (nfs version, rsize, wsize, sync/async, hard, 
soft etc ...). On the server I can have a look at /var/lib/nfs/xtab

$ cat /var/lib/nfs/xtab | grep arvouin
/mci/mci        
arvouin.int-evry.fr(rw,async,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,subtree_check,secure_locks,acl,mapping=identity,anonuid=-2,anongid=-2)

but I am often changing options on the server (for tunning purpose) , 
and hence I want to check that my clients is mounted with the latest 
options,  do I need to remount on the client everytime I change options 
on the server ? (exportfs -r -v -a)  ... .checking what is the current 
options on the client would be more clear to me .

thanks.

PS other lines are also not clear in /proc/net/rpc/nfsd
are they clearly explain somewhere ? or is there a better tool to read 
them ?
