Adding new host to pool failed
-
@tony It shouldn't matter since the hosts are in the same pool, it should list both of them. You can run it against both hosts to be sure
-
@nick-lloyd They are not in the same pool yet, because of the error above, the new host cannot be added to the pool. I ran the
host-license-removecommand on the new host and still the same thing, the result of thehost-license-viewremains unchanged. -
More information, both are XCP-ng 8.2.1, I ran the
host-all-editionscommand and both returns justxcp-ng -
@tony Huh, interesting... What hardware is in each of the hosts? And can you double check that you're running similar-ish firmware/bios on both servers?
-
@nick-lloyd They are both xeon but around 4 generations apart, how do I check if they are compatible? I have successfully added a non xeon with a xeon to the same pool before (there were warnings that some feature set will be disabled) so I thought this should be fine too, but please let me know otherwise.
-
@tony That should be fine, are you adding the older host to the newer host's pool, or vice-versa? My guess is that the newer one needs to be added to the older server's pool so that it can "properly" mask the CPU features
-
@tony And again, double check the BIOS updates. There may be a bug fix in one of them for Xen
-
@nick-lloyd The new host is has new CPU, the old host already in the pool has older CPU. I will try to update the BIOS of the new host and see if it helps. I don't think the old host will have any updates.
-
Updating the BIOS of the new host made no differences. So I tried to add it to my test pool and what do you know, it works without any issue and the test pool has a master of even older CPU so I don't think its compatibility issue.
There must be something wrong with my main pool that I'm trying to add the new host to.
-
Ok figured it out at the end using
xe pool-liston the existing pool gives me a list of existing hosts on the pool, and there was one that has been taken offline, without detaching in XO. So I did axe host-forget uuid=<host uuid>becausexe pool-ejectdoesn't work on offline host. And now I can add the new host just fine. Thanks everyone for helping!
