VSS/previous versions display only snapshots from year 2017


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
Vserver  Volume   Snapshot                                  Size Total% Used%

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.




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.

View solution in original post



Hi, Folks ! 


Today we are update to the 8.3.2P9 and the problem Fixed. 





Luiz Gustavo - HDI




Running 8.3.2P5, We only saw snaps from 2016. After upgrade to 8.3.2P9 that problem is solved, but only on the root folder of a share.


If you go to previous versions on any folder below the share folder, snapshots are not listed correctly.


Seems the dates came along after a while and it's showing correct now.


Hi Guys,




Bug 1057844 is fixed in version 8.3.2P9 and will in 9.1P1 be fixed too. Unfortunaltely version 9.1P1 is not yet available for download.

The 9.1 has become GA 3 days ago.








Good news!

Thank you for the information!


as we are midst in the planning phase for upgrading our MC cDOT systems to 9.1 (upgrade is planned for end of january) we will do it with 9.1p1 when it is released.


a p after a rc is always a good one 🙂




As per Description in the Details for Bug 1057844 ONTAP 9 Versions should not have that bug. But i've not verified that myself on an actual installation.


This issue exists in ONTAP versions 8.3.2P4 and later,
 but does not include ONTAP 9.0 and later.

Source: http://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=1057844

 I can commit that this Bug exists (contrary to the description in the Bug Details) as well in cDOT 8.3.2 GA, the release we are running our Systems. 


We have a few systems running 9.0 and they do have this issue. Number 1 below seems to indicate that at least some aspect of this bug exists in all versions.


9.1GA was released after this bug was marked as fixed, so just curious if it also still has the bug.


 1. Snapshot copies taken during December 31 of a leap year such as 2016 are
 not enumerated properly and those Snapshot copies and any earlier Snapshot
 copies are not shown to clients. This issue exists in all ONTAP versions.



Does the newly released 9.1GA have this bug?


Bug has supposedly been fixed in newly release 8.3.2P9. Haven't had the chance to upgrade to that version yet to test.


Does anyone know if this bug is in ontap9?


We too had this issue, could only see 2017 snaps in previous versions, but as of this morning it appears to have automagically resolved on multiple clusters/svms.  We had a case opened to track this, I'll make sure the engineer is aware things look OK again.  Very strange.


We also have this problem and can only see snapshots from the 2nd Jan 2017 till now.


Does anyone have an ETA on a fix?




I have the same problem. do you have any solution?? I can see only snap of 2016






We've got the same issues:


First System:

NetApp Release 8.3.1P1

- > Only Snapshots between today and 01.01.2017 can be accessed/viewed.



Second System:

NetApp Release 8.3.1P1

- > Only Snapshots between today and 01.01.2017 can be accessed/viewed.



Any Updates from NetApp?




Also facing this issue. Any ETA from Netapp?


I'm seeing the same thing on 8.3.2P1.  Thumbs up on linking to the bug ID, saved me from spending time to open a case with support.


"Not fixed in any Data ONTAP releases".  See NetApp bug 1057844:




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.





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).


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.


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.
