Replication task to an Ubuntu 20.04.4 LTS server. Replication started to fail with the following message last month.
I've not been able to find any information on this feature flag number. I assume this means a ZFS feature flag.Code:
Replication "main/vm_storage -> rpool/backups/vm_storage" failed: stream has unsupported feature, feature flags = 3420004 No error..
So clearly something was enabled on TrueNAS that Ubuntu doesn't like. My issue is that feature flags are not documented in numbers like that. I have no idea what "3420004" feature flag represents. And not sure what the "No error" is about since the replication fails. Whatever this is, seems specific to this dataset as all other replication tasks to the server continue to work fine.
Logs from Task:
