DFM server constantly crashes after filer backup

HASMIK_HAYRAPETYAN — Thu, 05 Jun 2025 05:43:27 GMT

Hi all,

Some of drives of our filer went bad in the array, filer went down. And we had new ones put in and filer went online. But now DFM server monitoring that filer constantly keeps crashing:

What to do?

Thanks a lot for any help,

Hasmik

Hello,

That error message and related dfm server process crash are further proof that you are indeed hitting bug 770795 (as Adai pointed out).

Thanks,

Kevin

Hello Kevin,

The bug Adai pointed out was about filers with duplicate aggregates, but in our filer we don't have duplicate aggregates.

Regards,

Hasmik

Hi Hasmik,

The complete details for that bug are not yet online. However I assure you that the footprint you have observed is that bug. The crashing will be fixed via a code change in an upcoming UM release.

The duplicate aggr situation could happen after disks are inserted into a controller that contain partial data from a previous aggr, and that which now show as a partial or complete aggr with a name that duplicates another in the controller.

You might check "aggr status -r" and ensure there are no incomplete or duplicate aggr names on the controller you referenced.

Additionally, are you using the VMware NetApp Storage Adapter in your environment?

Thanks,

Kevin
