Issues joining pool with less pif on the newest host
-
Hello there,
We have a production pool (2 hosts) that is in dire need of a new host, so we removed an newer host from another pool, but we stepped on something that i knew could be an issue.
The production pool has 2 hosts on xpc-ng.8.2.1, that had issues updating to 8.3, each host has 8 PIF interfaces, 4 copper 1gbps, 4 fiber 10Gbps. 2 of the copper PIF are not used. The newer host only has 6 PIF, 2 copper 1gpps and 4 fiber 25 Gbps.
I made sure the PIF order on the new host matches the order of active PIF.
When i try to add the new host to the pool, the dom 0 on the new host stops having network access, and shows no PIF. Configure Management Interface reports <no interfaces present>.
I bet the issues is the PIF mismatch, is there anyway i can disable the unused PIF and get add the new host? Can it be a software version missmatch? we didn't update the new host after install, because the pool is one patch behind.
Bonus question, is there a way to install guest tools on older Operating systems, like windows XP and centos 4, for some old guest systems we need to keep arround ... (yeah i know we should get alternatives ...)

@afmart_dei I'd be surprised that you can't add this host to the pool because it has a different number of PIFs... more likely than not the version mismatch is what is getting you hung up here.
Is there anyway to update everything to the same level, once that is done then you should be able to add this host to the pool.
As for Windows XP, CentOS 4 (CentOS 4 was EoL'd in 2012.... only 14 years ago) so that's likely gonna be a hard no. XP was in 2014.. likely the same boat.
The issue likely being that no one wants to program on old ass OS's to support something that the original dev no longer supports.

I had similar issues recently. But not exacly the same. I was able to add second host to pool but was not able to work because in my case eth0 was host managment, eth4 storage, eth5 migration, eth 7 vm network. My second host at the time did not have eht7
Then i further messed myself up by using second host as its own pool attached to same storage and when down hill form there, but was an easy fix.

@DustinB The issue is lack of pool resources to have all prod machines up, if i can't join the new host withou update, i'll have to schedule some downtime.
