Storage Mover - AZSM1042 - CLAIM TARGET FAILURE]

Question

Storage Mover - AZSM1042 - CLAIM TARGET FAILURE]

Phil 291

Hello together,

i have an Issue with the Storage Mover.
i tried to synchronize an onPrem Fileshare with an Storage Accoun File Share.

The Storage Mover displays the error “AZSM1042 -CLAIM TARGET FAILURE]” when executing the job.

The FileShare is onboarded with an private Endpoint.
The necessary Right for the Identity are configured on the FIle Share Level.

Here is the complete error message:

Job failed state transition: (Started,Claimed -> Failed,Claimed). Message: Failed to claim target container Container in xxx: [CLAIM TARGET FAILURE] Unexpected error occurred while attempting claim on target container: Put "https://xxx.file.core.windows.net/xxx/__AZURE_STORAGE_MOVER_MARKER": EOF

What has already been tried:

The STorage Account was changed to Public Endpoint for an test.
An attempt was made to specify the fileshare directly as the destination and not a subfolder

The Microsoft Docs Troublehsooting Steps does not really help.

There it is described that it is a temporary error and otherwise you should open a Microsoft ticket.

Any Ideas?

Thanks.

Best Regards,
Phil

Hello @Vinod Kumar Reddy Chilupuri ,

thanks for your Answer.
It helpes not really for the Problem.

Permissions are set on the Storage Account and on the Fileshare level direct

I said it before i tried the same with the public Endpoint -> Same Error

What do you mean with detailed Logs from Storage Mover?

To be honest, the logging and debugging for the jobs is not really well solved

The other Links doesnt work. But all i find about this Problem doesnt help.

Regards,
Phil
