Hostname changer and ad join is set per host. The global setting only impacts default when applying to a group or host.

@Mokerhamer

Imaging speed is determined on Stream->Decompress->Write to disk. (Technically the speed you see in partclone is purely the speed at which it’s writing to the disk.) However, this is limited to the amount of bandwidth in use to send the data.

As @george1421 showed, from a purely networking standpoint, the maximum would be 7.25 GB/min.

This is likely where you’re seeing a variance in the Unicast vs. Multicast.

I’m assuming in the Unicast instance, you’re sending the image to a single machine. So it’s got the full GB backbone available for network streaming. In the case of multicast, it floods your entire network (subnet basically) with the packets. It also has to keep a “steady” stream so the slowest machine in the group will be the entire limiting factor for all machines.

I’ll bet if you Unicast to 5 machines and Multicast to the same 5 machines, you’ll see a semi-evening out of the speed rates.

@george1421 right don’t forget that the amount of data written too disk is much larger because of the compression ratio which is why the compression medium and speed of decompression is so important.

Is selinux in permissive or disabled?

What’s output of sestatus

Please do not upgrade to this release on Ubuntu! We found an issue with this release that only is caused if you are on Ubuntu and want to upgrade from an existing installation. Otherwise you are save you use 1.5.7!

@Rivybeast What about:

SELECT hostName,iHostID FROM fog.inventory LEFT OUTER JOIN hosts ON inventory.iHostID=hosts.hostID;

Likely will be huge again.

@Sebastian-Roth From the sounds of things, “Blank Page” is not quite what it seems in this scenario.

The Page itself is loading perfectly fine. The “Headers” are displaying, then disappearing. This is likely because there’s no inventory data to print to the screen.

What’s the output of mysql statement:

select * from fog.inventory \G

This is really good information. I suppose it could be useful especially with the speed of NVMe usurping so many other disk access things, maybe udev is the issue the whole time in regards to “sporadic access” and usability?

Thank you all for the debugging and communication.

@Sebastian-Roth Typically it would be found in /var/log/php-fpm/www-error.log
