Slow General performance - troubleshoot Netapp Filer

Greetings people.

On of my filers has NetApp Release 8.0.3P3 7-Mode , and it is a model FAS2040.

The capacity of the filer is now filled 98%.

I have periodic slow respone from the CIFS and NFS clients.

What could I do in general to troubleshoot.

thanks in advance.

Re: Slow General performance - troubleshoot Netapp Filer

Ok, let's tackle the first issue...

If you say your aggregate is 98%, that's obviously going to affect performance.

You are also running code that should be updated if possible.

What is your disk layout?  Are you disk bound

priv set diag

statit -b

Wait 9 seconds during peak work load

statit -e

You should see what the disk UTs are ..

Also, sysstat -m 1

Re: Slow General performance - troubleshoot Netapp Filer

Thanks for the fast reply.

To answer your questions, the disks are organized, or as you say bound into one Aggregate (aggr0). That is I know not good organized as Performance based, but this was before my time.

As for the priv statistics I will post them at Peak time, and also the CPU.

What will I achieve with the stats?

I also have one Linux CEntos NFS Client that is always having only 1.2MB/s copy Speed and the other have 80MB/s which is ok. No matter what I do on the Client it stays the same.

When the Peak hours are , some Client can normal open the CIFS Shares and some cannot, or it is really slow.

I have also a HA pair and another one with SnapMirror. That are working ok, but the Primary one is slow, gets slow.

I have managed now to free up some space. Will do some more. But the space is always the Problem.

What I wanted to do , is to troubleshoot, and see if something else is impacting the Performance.

Thanks in advance.

Re: Slow General performance - troubleshoot Netapp Filer

Another one.

Should I update the Data Ontap? Can I do it painfully without Netapp support ?

What is the downtime, what should I gain with the newer version?

P.S. Still I am not able to see why is this particular client limited to 1.2MB/s transfer to NFS shares (the centos one), and on other filers the speed is normal (80-90MB/s).

All the other , the same workstation clients have normal speed there with the same NIC cards, same OS, and same settings.

Thanks in advance.

Updating Netapp Ontap is as easy as well.. anything..

I can't comment until i know how big your aggr is, how many disks and some stats...

Thanks for the Support.

I have two FAS2040 Heads.

These heads have three Filers DS2342 with 24x450GB

The two heads are configured as a HA Pair. And I have another FAS2040 Head with Snapvault configured for some of the volumes. This third head has 24x1TB drives.

Total space assigned for the aggr0 is 19TB.

Here are some stats:

I would like update Data ontap on all three Heads, some how to would be great.

And also I would like to solve the performance issues, these statistics are not under heavy load, but I will send them also.

I still have this NFS Centos client that only has 1.2MB/s transfer speed only with the filer01. The filer02 and filer03 have normal speed transfer when I mount this client.

I have started to free up space on the volumes.

Now the aggr0 is only 93% full, this will go more low as I clean more data.

Also I have noticed that ACP has not full connectivity:

Or this ACP is only temporary now?

Any help is appreciated.

Thanks in advance.

Re: Slow General performance - troubleshoot Netapp Filer

Ok, so let's tackle this first.

if these are your filer stats under load, your filer is sleeping like a baby.  Not CPU bound and not disk bound.    As for upgrading, you need to have support on these boxes, and run upgrade advisors from my support. 

For the HA pair, ACP is a plus, helps the cluster shelves out.  For optimal cluster performance you want this at full connectivity if it's cabled up properly. (Google that part)

i'm a little perplexed how the linux box copies fine to two of the three heads, but only receives very slow speeds coming from the one head.

You can turn on nfs client statistics on that head and try copying it and see what's going on.   Check your port configurations on the vif as well, make sure you don't have a duplex issue or something silly.

Re: Slow General performance - troubleshoot Netapp Filer

Thanks for the fast reply.

  To further explain , filer was not at full load, and yes this is not so much, it is sleeping 

  As for the upgrading, I have tried to contact a local Support in my Country and still waiting for an answer. Does this come free? So I cannot do this without them ? The upgrade advisor?

  I will Google why I do not have the full ACP connectivity, and will check the cables.

As for the Linux BOX, this is a mistery to me also, the cabling to the BOX is ok, and it is FULL Duplex, 1000MBit, I have tried a lot of NFS Settings, but still slow. This is for sure something silly.

Could I turn on options nfs.per_client_stats.enable on, and then what should I do to collect the info and post it here? To further troubleshoot?

Thanks in advance.

Re: Slow General performance - troubleshoot Netapp Filer

a 2040 filer is pretty old, so you might not have support on it,  But you should be able to go to now.netapp.com and click mysupport.  You can generator your own autosupports on there as well..

Run a compare on your nfs options on each controller to see if something is different.   What's wierd is you state it goes ok to the other node in the cluster.

Just turn on nfs stats and see if it points anything out.  no need to post

Re: Slow General performance - troubleshoot Netapp Filer

Greetings.

I have turned on the NFS stats per client, and I have choosen to collect the stats for this current Linux BOX.

I have used the dd to test the speed once more:

dd if=/dev/zero of=file.out bs=1MB count=10

10+0 records in

10+0 records out

10000000 bytes (10 MB) copied, 8.56381 s, 1.2 MB/s

And as you can see the 1.2 is to slow.

During the copy I did the nfsstat -h 192.168.0.xxx

Here is the output, I could not find anything fishy about it:

naqpunkt01*> nfsstat -h 192.168.0.xxx
