Can anyone help me , How to disable smb1.0 in isilon , currently we are running on one FS 8.0.3,If we disable will be there any impact, Kindly help me

Also I'd suggest in addition to what Peter mentioned, do some spot-checks. 

Do you have any clients actually using v1 still?

isilon-1# isi statistics client -nall --protocols=smb1

Ops In Out TimeAvg Node Proto Class UserName LocalName RemoteName

Versions of SMBv1

Keep in mind that Isilon doesn't even support very early versions of SMBv1, (which used ASCII for setup and teardown), which once in a while can break things during a migration to Isilon:

• HPUX with built-in CIFS client
• AIX with built-in CIFS client
• NT 4.0
• Scanners or MFPs built on really old Windows Embedded

Since you're running now without an issue it's likely that all of your clients are at least beyond that hurdle, so the impact is likely really low.

To be sure:

But maybe write a shell script to run that command once per hour for a week, and append the results to a log file.  Then you can go to your change control board (assuming you have one), and say, hey, nobody is using this, and it's antiquated and slow, I want to turn it off please.

Thanks a lot Chris,For explaining me in detailed.

I had one more question could please help me with this:

InsightIQ version (4.1.1.3) will it be compatible with the Linux Server of CentOS version 6.9..?

Thanks Peter , for helping me with document

Well the install guide for 4.1.1.2 states that it supports CentOS version 6.9 and RHEL versions 6.8 and 6.9, so I don't see why that would be a problem.  I don't see a doc for 4.1.1.3, but I doubt that CentOS 6.9 support would be dropped from a minor release like that.

See page 9 of this document:

Hope it helps,
