Have a serious problem, and I will try to first give the facts:
Version 8.2.3 7-Mode
We lost communication with both primary filers yesterday. It looks as if there is a authentication problem. I am unable to log on with my elevated account, but I can log on with a local account. If a customer reboots, they will lose connection.
Strange, I can access the DR filers with no issues...
I have rebooted the filers this morning, still unable to access the filers with elevated account via SecureCRT and NetApp OnCommand.
All protocols, CIFS, NFS, iSCSI, and FC/FCoE are enabled.
NOTE: In the CIFS windows, I have clicked on the Options TAB and went to Access Security. The Enable SMB is NOT checked.
I am now receiving a email from the primary filers stating Configuration Error with the following link
We do not have NetApp support at this time due to a lapse in the contract. We will finally get support in the next two weeks when they upgrade our systems.
So, does anyone have an idea what is wrong and how I can fix this?
First, thanks for the quick reply.
To answer your questions, the only problem that the clients are having is that they cannot connect to the filers to get their data.
As to SSH'ing, I can do that with a local account, but not the AD account
if your time is within 5 minutes you need to type
if that doesn't work, you need to check the AD account to see if the machine account is messed up.
and your max skew should be set at 2m
Did you apply the patch ? latest SMB1 disable patch on windows 2008 or higher server
There is a option you have to enable, its explicit options, we had the same issue
options cifs.smb2.client.enable on
and do cifs dctest or resetdc
first wait few min and check if it picks up automatically
Already tried that, was hoping that you had another way to try.
It is beginning to look like our higher headquarters did something to the DCs which caused this. Just waiting on the word now.
Appreicate the support. Thanks.
Found the resolution. When they upgraded the DCs to SMB2, SMB2 was enable on the filers, but, the line cifs.smb2.client.enable was missing. So, I typed in options cifs.smb2.client.enable on, and within ten minutes, we were up and running.
Thanks for the support.
