I am running Data ONtap 8.0.2 7 Mode. I run CIFS on both filers. Both are setup the same. The only error I see on one filer that I don't on the second is Kerberos: Did not find principal cifs/Filer1@mydomain.com in keytab. This is a CIFS problem.
--The answer I found was rerun the CIFS setup, which runs successfully. But the error persists.
So I tried:
-resetting the computer account
-deleting and creating a new computer account
-cifs domaininfo (looks correct)
-cifs testdc (connects to the local DCs just fine)
-setting preferred DCs
-not setting preffered DCs
-compare allthe cifs options between the two filers (the match 100%)
So I am baffled why these 2 identical filers are behaving in a similiar manner. I believe the key is
"Kerberos: Did not find principal cifs/Filer1@mydomain.com in keytab. This is a CIFS problem."
I just can't seem to find anything else to try. Any suggestions?
The options match, at least the ones this version has available. I don't have:
DNS and preferred DC settings are the same.
I understand that a Kerberos ticket would expire after 10 hours, so I believe that is the root of my problem. The working Filer obviously gets a new ticket, the clunky filer (which I currently hate in a way someone should not hate an inanimate object) does not get a new ticket and the CIFS drop. But why? why?
Sorry this has had be baffled for weeks now and everymorning I need to cifs resetdc to get it started. I do appreciate your suggestions very much.
I am having the exact same problem. Multi Path HA pair running DOT 8.0.2 7Mode. Same configuration on both filers. Every 10 hours I have to reset cifs to bring the connection back to the domain controllers.
