Hello,

In a backblaze backend I'm seeing lots of warnings like this:

Encountered B2Error (503 : service_unavailable - no tomes available), retrying ObjectW.close (attempt 3)...

It looks it's some sort of timeout. Is there any setting that can solve this?

Thanks.

Hi,

Encountered B2Error (503 : service_unavailable - no tomes available), retrying ObjectW.close (attempt 3)...

does S3QL stop or is this just a warning? Looks like a "tome" is a storage unit ( https://help.backblaze.com/hc/en-us/articles/218485257-B2-Resiliency-Durability-and-Availability ) and B2 had none available there for a while.

It looks it's some sort of timeout. Is there any setting that can solve this?

The S3QL B2 backend should handle these according to https://www.backblaze.com/b2/docs/integration_checklist.html so there actually is no need to "solve" this. S3QL should retry the upload for 24 hours when getting these warnings.
