Strange behavior on files and dir created from Windows.

Hi all,

  first post here so apologize for every error I could make.

I have an isilon cluster where I'm studying and I've noticed a very strange thing ( in respect to what I see on some "made by other"  isilon clusters).

When looking at files created by windows on a SMB share here is the output:

IsilonTest-1# ls -l

total 68

-rwxrwx--- +  1 1000006  1000008   9 Apr  9 14:46 New Text Document (2).txt

-rwxrwx--- +  1 1000006  1000002  49 Apr  9 14:41 New Text Document.txt

As you can see, the UID and GID is numeric, while I have seen this in other cluster with their original names.

If I look at my authentication providers everithing seems fine, but eventually is not:

IsilonTest-1# isi auth status

ID                                     Active Server     Status

----------------------------------------------------------------

lsa-activedirectory-provider:PIGI.PRIV Pigi-AD.PIGI.PRIV online

lsa-local-provider:System              -                 active

lsa-local-provider:TestAccessZone      -                 active

lsa-local-provider:pippo               -                 active

lsa-local-provider:ThirdAccessZone     -                 active

lsa-file-provider:System               -                 active

----------------------------------------------------------------

Total: 6

IsilonTest-1# isi auth ads view PIGI.PRIV

           Name: PIGI.PRIV

         Status: online

Primary Domain: PIGI.PRIV

         Forest: PIGI.PRIV

           Site: Default-First-Site-Name

NetBIOS Domain: PIGI

       Hostname: isilontest.pigi.priv

Controller Time: 2018-04-09T17:36:52

Machine Account: ISILONTEST$

       Groupnet: groupnet0

I have some suspect, but would like to initially discuss about this without talking of it, just to not give false ideas .

What, in your experience, could cause such behavior ?

Thanks in advance

I have finally managed to understand which was the problem.

Every check from the troubleshooting guide was OK, so I need to "open the mind" and look better.

The problem was that in the "System" zone was missing the Active Directory provider.

I have then modified the zone to use also the ADS provider and now everithying is working as expected:

IsilonTest-1# ls -ltra

total 18

drwxrwx--- +  2 group  PIGI\domain users    0 Apr  5 19:12 OkShare2

drwxrwx--- +  3 group  PIGI\domain users   24 Apr  5 19:30 OkShare1

drwxrwx--- +  2 group  PIGI\domain users    0 Apr  6 09:18 home

drwxrwx--- +  2 group  PIGI\domain users    0 Apr  6 09:31 MultiRightShare

drwxrwx--- +  2 group  PIGI\domain users   91 Apr  6 12:55 sharedup

drwxrwx--- +  7 group  PIGI\domain users  133 Apr  7 09:09 .

drwxr-xr-x    3 admin  admin               27 Apr 11 09:11 ..

Thanks to all for your help ! It has been really important !!

  1. What version of OneFS are you working with? 
  2. Have you checked to see if there any SMB patches available for the version your on?
  3. What version of Windows OS are your using to write to the test Isilon cluster?
  4. Does it have the latest patches?
  5. How many nodes are in this test cluster?
  6. Do all the nodes have an active connection to the AD server?

Knowing this will help with the troubleshooting process.

Chris,

thanks for your answer, and my bad for not giving such information in first post.

1. Onefs is 8.1.0.0 ( I'm using the isilon on virtual machines, as study environmnent )

isi version says: Isilon OneFS v8.1.0.0 B_8_1_0_011(RELEASE)

2. I haven't check for patches.

3. 4. AD Windows is win2012 R2 DataCenter ( not patched )

5. I have three nodes in cluster .

6. As far as I can tell yes:

IsilonTest-1# isi auth ads list

Name      Authentication  Status  Site                  

---------------------------------------------------------

PIGI.PRIV Yes             online  Default-First-Site-Name

---------------------------------------------------------

Total: 1

IsilonTest-1# isi auth ads spn check PIGI.PRIV

No missing SPNs found.

When you see UIDs and GIDs in the 1 million range, this means that OneFS was unable to map the name of the user and/or group to a proper UID/GID.  I see that you have multiple access zones so be aware that the mapping is done on a per access zone basis so while all of your providers are active, they must be properly assigned to each zone as appropriate for your environment.  The cluster will use the providers assigned to the specific access zone being accessed by the end user to do a match.  This is important because the System zone can see all of the cluster, so if you map a share through the System zone, it's possible to access data in a different access zone, but you will be using the System zone authentication providers in that case which could cause a mismatch.  I'm not saying that's what's happening here, but it's just one possibility of an improperly mapped user/group.  There are certainly other ways this can happen though.  But my goal here is to hopefully set you on a path to find our your specific mapping issue.

My bad, again.

I should also explain better how I'm configured.

There are a bunch of access zone, but they are only tests. Not using any of them, except for "TestAccessZone".

The ADS provider is defined in "global" configuration and used only in TestAccessZone.

The only real zones are the System and the TestAcessZone.

Have a look a the relevant trouble shooting guides from this page

Hi, I'm sorry I did not understand "the zone was not using the provider".  You listed it out and the system zone was active.  Where is the command to find if the system zone is using the provider?  Sorry, I did not follow this.

Thanks for the tip!. My issue wasn't the same as yours, but adding AD to the system zone resolved my problem.

Cheers!!
