nss file browsing

Why is it that I can cruise through nss folders and then get to a folder that completely hangs while trying to open? The folder can be pretty small with just a file or two, and doesn't typically have a deep path. Anything in the folder will take awhile to open or delete, even a small file.

Anyone else see this kind of thing?

Yup, same thing here. Our servers are fully virtualized:
-VMware ESX 3.5i

--OES2 SP2a
---Three dedicated eDir servers
---Four file & print cluster nodes
---Four GW cluster nodes

-Xiotech Magnitude 3D 4000 FC SAN

-3300 WinXP SP3 client machines,
--Novell client 4.91 SP5
---Updated to IR1 that was released on Sept. 30, didn't help

-A handful of Win7 machines (same problem occurs on both platforms)

We performed some packet traces today with Wireshark while on a mirrored port, and every time the client hung, it was when the it sent this NCP packet to the server:

"Get Object Disk Usage and Restrictions"

...5-20 seconds pass...

Server finally responds with the info, and everything is zippy again.

Completely random, and completely frustrating.

Have you made any headway on your end with this? What does your environment look like?

Hi,

Please be aware of various tunning parameters on nss which came into
full effect with the latest patch release on oes2sp2

Look for 31.0 Tuning NSS Performance on Linux in the documentation.

Hello,

did anyone find a solutions for this problem? I´ve got the same problem at one of our customers.

- 2 Node OES2SP2 (latest patches) Cluster
- 9 NSS ClusterPools

When browsing the FileSystem, the Explorer stumbles and hangs for a a view seconds. First I thougt the VirusScan engine is the culprit, but disabling the agent on the client ofters the same result.

When browsing with the same Client on a OES2 Netware Server everything is fine. I´m able to browse the filesystem in a fast way and nothing stumbles or hangs...

Any suggestions for this problem?

Thanks!

Regards
Michael

For us, it turned out to be a Nagios script that was checking the NSS volume free space on the OES2 Linux servers. Disabled that particular check, and the problem went away.

This is the script that was causing us issues:
Nagios Exchange - check oes linux nss volume usage

If this doesn't apply to you, have a look at the latest client releases from Sept. 30th 2010, as they contain some fixes that might help as well.

HTH,
Alex

Re: nss file browsing

Hi,

What you could also look into is tuning NCP, I mention this since NCP uses caching, if this is left default it can in some cases turn into slow displaying of files and slow access times, especially if on a volume are a lot of small files, and the server has not much RAM available.

Check out TID 7004888 for tuning NCP

You might also have a look at TID 7006996, that contains some overall OES2 tuning.

Cheers,
Johan

Re: nss file browsing

Hi,

thanks for your answers...
If will give the TIDs a try - in hope that they will speed up browsing in the filesystem... 🙂
I will report the results!
