Since about one week harvest seem to have problems getting volume capacity information from OCUM server.
We have not changed anything with OCUM and nothing with harvest but I suspect that this is related to a clone of a FlexGroup volume which was created at this time.
The harvest error log shows:
[2021-01-24 21:15:09] [WARNING] [volume] update failed with reason: Object [id=3180037] was not of the specified subclass [com.netapp.dfm.entity.inventory.ontap.storage.FlexVol] : loaded object was of wrong class class com.netapp.dfm.entity.inventory.ontap.storage.FlexGroup
[2021-01-24 21:15:09] [DEBUG ] [volume] data-list poller next refresh at [2021-01-24 21:30:00]
[2021-01-24 21:15:09] [WARNING] [volume] data-list update failed.
I also started the worker with -d but there seem to be no other useful info in the logs. (if necessary I can provide a full log but because of our number of volumes it is huge)
