VSS/previous versions display only snapshots from year 2017

[ Edited ]

Happy new year 2017 everyone! Robot Happy

 

It is Monday January 2nd in 2017 and when right clicking a fileshare > properties > previous version, I can only see snapshots from year 2017.

 

If I list them from the cluster management, I can see there are more:

 

clustername::> snap list -vserver vservername -volume volume_name
                                                                 ---Blocks---

Funny, right?

 

I have requested Netapp support to take a look, but I thought to post it to discussions as well.

 

EDIT: running Ontap 8.3.1.

Re: VSS/previous versions display only snapshots from year 2017

Hi there,

 

i have the opposite problem,

in PV i can only see snapshots until 30.12.16 , all snapshots after thar ar invisible in PV.

But i can see them (and use them) when i do ~snaphot

 

really odd

Re: VSS/previous versions display only snapshots from year 2017

Hi Again,

 

the difference seems to be on which version of cdot you are on

 

i'm on  8.32 p4 and i dont see 2017

Re: VSS/previous versions display only snapshots from year 2017

Same problem here:

 

 

With previous versions from explorer, we only see back to 01.01.2017. 

 

Wth cmd \~snapshots\ we see snapshot back to 2015.

 

 

Ontap: 8.2.3

Re: VSS/previous versions display only snapshots from year 2017

 

It is new bug http://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=1057844

 

Engineering is working on the fix.

 

Issue with date conversion encryption logic.

Same problem here

 

one system with ONTAP NetApp Release 8.3.2P7 see only previous versions listed up to 31.12.2016 00:10 but newer snapshots are existing on Volume

one system with ONTAP NetApp Release 8.3.2P2 see only previous versions listed from 2017 but older snapshots are existing on Volume.

Re: VSS/previous versions display only snapshots from year 2017

Same thing here. With Data Ontap 9.0P1 we only see Snapshots from 2017.

 

As a workaroud, can you browse the snaphots via CIFS (.snapshot or ~snapshot-Directory)?

 

These Directorys arent available in our environment, altough the option "Snapshot Directory Access Enabled: true" (Command: volume show -instance -vserver [vserver] -volume [volumename]). And also "show-previous-versions" is set (Command: vserver cifs share show -share-name home$ -fields share-properties).

Re: VSS/previous versions display only snapshots from year 2017

Hi, the ~snapshot or .snapshot directory is not visiable in windows explorer (SMB2.0 limitation I believe), but you can use the dir \\<vserver>\<share>\.snapshot from a CMD window and it will display the snapshots. You can then browse the snapshot required in explorer using the following syntax \\<vserver>\<share>\.snapshot\daily.2016-12-08_0010.

 

Hope this helps.

Re: VSS/previous versions display only snapshots from year 2017

Hi Guys,

 

 

We have faced more or less the same issue. In our case we see only the 2017 snapshots instead.

Wa have opened a Netapp case and will keep you informed.

Hi Ketan,

 

thanks for that hint regarding the SMB2 Limitation. I could browse the ~snapshot-directorys after disabling SMB 2 on a test client. This helps us, to work around the problem and make restores untit the issue is solved.

 

Thanks so far.
