VSS/previous versions display only snapshots from year 2017

[membit]

Happy new year 2017 everyone!

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.

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.

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.

Regards.

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 🙂

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.
