List hosts mounting NFS exports

[Gumar K]

Guys,

How to get a list of all hosts that are mounting a NFS export from Isilon ? In celerra it is pretty simple we can use /usr/sbin/showmount -a DM command and that will give the info. What is the equivalent command in Isilon.

This command will show the count of all the connected and active clients, but how to get the hostname or IP address the clients.
# isi statistics query --nodes=all --stats=node.clientstats.connected.nfs,node.clientstats.active.nfs

This command will also shows the NFS clients, but I believe they are the active clients and not showing all NFS clients including inactive but NFS mounted clients.
# isi statistics client --nodes=all --protocols=nfs3

Also, Is it a best practice to delete the default /ifs NFS export from the cluster? Does it impact Insight_IQ servers? I have seen InsighIQ servers mounting the /ifs folder periodically while the FSAnalyze job is running. So if we delete the /ifs export will it still work ? The datastore on the IIQ servers are still local disks and not using Isilon datastore.

thanks,

G.K

showmount is there on the isilon.

try:  isi_for_array showmount -a localhost

Showmount works. Thanks Dan.

I just discovered this command: isi statistics client -d

It only seems to show "active connections".

Hello GK,

Use below command to find the remote address of all NFS3 client connections. 

#isi statistics client --nodes=all --protocols=nfs3 --orderby=remotename

Thanks, Paddy

In 7.1 this has changed to isi nfs nlm sessions list. the equivelant in smb is isi smb sessions list.  This is PER NODE and does not account for the cluster as a whole.  I'd like to have that figure as well if anyone knows it.

isi statistics query --nodes=all --stats=node.clientstats.active.nfs,node.clientstats.connected.nfs

Thank you for this! I expanded it in search for all connected clients and cut off headers and footers

isi statistics query --nodes=all --nofooter --noheader --stats=node.clientstats.connected.cifs,node.clientstats.connected.ftp,node.clientstats.connected.hdfs,node.clientstats.connected.http,node.clientstats.connected.iscsi,node.clientstats.connected.ndmp,node.clientstats.connected.nfs,node.clientstats.connected.nlm,node.clientstats.connected.papi,node.clientstats.connected.siq,node.clientstats.connected.smb,

I'm not convinced this will catch 100% of clients.  I the client mount by UDP, I think they will be missed unless they are constantly checking and the client does IO during one of your runs of this command.

In doing an isi statistics list stats, I don’t see anything referencing udp.

[Erik Weiman]

Does it show up in /var/db/mountdtab?

[Jerry Uanino]

honestly to prevent being nixed by version changes..... netstat -an |grep ESTA | grep 2049 |wc -l

for the udp stuff,  i stuff I'd have to think harder.

but really.... why are you using udp anyway?
