Xenserver Host unable to reconnect
We have a zone that has a single host in it. We also recently updated to 4.0 from 3.0.2 (this may not be relevant but figured I'd mention it anyways). We put our host in maintenance mode (all VMs were shutdown, etc) and applied some patches that were waiting to be applied. After coming back up, it now is unable to reconnect, when I try to force reconnect, I get the following in the management log:

I can't find in the logs where it's trying (besides the force reconnect) to reconnect on it's own. I do see where it acknowledges the state of Alert for the host, but doesn't give any reasoning as to why.
The only thing I can see any indication it's even trying is this line:
2013-02-11 11:47:05,670 DEBUG [xen.resource.XenServerConnectionPool] (ClusteredAgentManager Timer:null) Failed to slave local login to 10.5.1.14

10.5.1.14 is the host that should be reconnecting but is not.
Anything else I can look at as to why it's not connecting? Any suggestions on why my host won't reconnect?
Thanks

Re: Xenserver Host unable to reconnect
Posted by Caleb Call <ca...@me.com>.
So, we're not sure what we did, but something happened and it allowed us to re-add it. We tried adding another temporary host to this zone, but that failed, then we were able to re-add this host and it worked.
I also found something, not sure if this change was intentional or not, but it looks like since upgrading to 4.0, the CPU Mhz is respected more. Our CPUs are 2.2Ghz CPUs, there's 32 of them, so it reports as 70400 Mhz as available. Our Computer Offering was set to allocate 2700 Mhz per core, and 2 cores. It seems that since each individual core is only 2200, it's less than the 2700 per core it was looking for, instead of just using it as a resource pool. It would fail and say no suitable hosts as the CPUMHz was false. Mind you these same computer offerings worked fine in 3.0.2. I created new offerings with everything the same, but only 2000 Mhz and now our VMs are starting up no problem.

RE: Xenserver Host unable to reconnect
Posted by Devdeep Singh <de...@citrix.com>.

Devdeep

RE: Xenserver Host unable to reconnect
Posted by Devdeep Singh <de...@citrix.com>.
Hi Caleb,
Do you have any instances running on the host? If not, then removing it shouldn't cause any problems. Can you also check if xapi is running on the host.
Regards,
Devdeep

Re: Xenserver Host unable to reconnect
Posted by Caleb Call <ca...@me.com>.
Tried this but still nothing. As I mentioned before, the mgmt_server_id is already NULL.
Here's a question for the group, if we pull this single host out of it's cluster, will it do anything to the VMs that area already in this zone? We have had similar problems in our other zones that have multiple hosts, but we've been able to pull those hosts out, rebuild them and re-add them and then everything is happy.
Can we do the same for a single node cluster?

Re: Xenserver Host unable to reconnect
Posted by Caleb Call <ca...@me.com>.
Tried this but still nothing. As I mentioned before, the mgmt_server_id is already NULL.
Here's a question for the group, if we pull this single host out of it's cluster, will it do anything to the VMs that area already in this zone? We have had similar problems in our other zones that have multiple hosts, but we've been able to pull those hosts out, rebuild them and re-add them and then everything is happy.
Can we do the same for a single node cluster?

No luck, the mgmt_server_id is already null.

Yes to both of those, I should have mentioned I have tried to make sure connectivity is still good. I'll try nulling out the mgmt_server_id in the host table and see if that works.

I can't find in the logs where it's trying (besides the force reconnect) to reconnect on it's own. I do see where it acknowledges the state of Alert for the host, but doesn't give any reasoning as to why.
The only thing I can see any indication it's even trying is this line:
2013-02-11 11:47:05,670 DEBUG [xen.resource.XenServerConnectionPool] (ClusteredAgentManager Timer:null) Failed to slave local login to 10.5.1.14

10.5.1.14 is the host that should be reconnecting but is not.
Anything else I can look at as to why it's not connecting? Any suggestions on why my host won't reconnect?
Thanks

I can't find in the logs where it's trying (besides the force reconnect) to reconnect on it's own. I do see where it acknowledges the state of Alert for the host, but doesn't give any reasoning as to why.
The only thing I can see any indication it's even trying is this line:
2013-02-11 11:47:05,670 DEBUG [xen.resource.XenServerConnectionPool] (ClusteredAgentManager Timer:null) Failed to slave local login to 10.5.1.14

10.5.1.14 is the host that should be reconnecting but is not.
Anything else I can look at as to why it's not connecting? Any suggestions on why my host won't reconnect?
Thanks

Re: Xenserver Host unable to reconnect
Posted by Ahmad Emneina <ae...@gmail.com>.
from the management server, can you ssh to that host? can you execute xe
commands on that host? if yes to both those, null out the mgmt_server_id
from your host in the host table... then issue the force reconnect. see if
that helps.
