PBS Local Sync to Remote PBS Stuck

[Dexter23]

Hi have configure a push sync from local to remote pbs, but since I configured it it has never worked:

PBS Local:

PBS Remote:

Hi,

please post the output of proxmox-backup-manager version --verbose from the pushing PBS host. Note that there was only limited log output for the push sync jobs previous to version 4.2. So you might just see no progress output?

running version: 4.1.0

you are still running on 4.1.0. Make sure you are up to date by running apt update && apt dist-upgrade, and restart the PBS services if required.

 

[Dexter23]

I upgrade the PBS to the latest and reboot, now i launch the Sync manually

PBS Local:

PBS Remote:

 

[Dexter23]

Nothing has changed at the moment no new entries in the task viewer is the same as the two screenshot above, it seems stuck as before, is there a log file to analyze to understand what it is doing?

 

[Chris]

How big is this particular disk image? Might simply take some time to upload? What bandwidth do you have available? Do you see network and write activity on the target PBS?

 

[Dexter23]

The bandwidth available on the local PBS is 20 Mbit/s Download and 6Mbit/s Upload.
This is the local datastore to sync to the remote:

This is the datastore from the remote PBS:

Network Traffic PBS Local:

Network Traffic PBS Remote:

 

[Chris]

6Mbit/s Upload

Well you are trying to push a disk image of up to 400GiB (actual raw size might be less, but still) over a 6Mbit/s connection, that will take some time...
You might consider pre-seeding the remote datastore by some other mean if possible, e.g. a sync via a removable datastore.

 

[Dexter23]

It has always worked, we had to delete and recreate the VM due to software problems and so now it has to reload the full backup but the available bandwidth has always been the same even before when it worked, only it is not normal that I do not even see the progress in percentage? Is there a log file to analyze to understand if it is actually progressing?

Update we have error:

PBS Local i can't reach, the ping works the ssh No:


PBS Remote:

 

[Dexter23]

PBS Local was freeze i force shutdown and poweron, this is the last portion of the journal log:
