Jeacuterocircme HAGUET Posted August 26, 2020 Share Posted August 26, 2020 Hello I have a XS 7.1CU2 pool with 3 servers. Unfortunatly, we had a power failure 2 weeks ago. On the first reboot, I was not able to contact the pool using XenCenter ... Then, I have rebooted one by one each server, and I was able to contact the pool I could restart all the VMs, and everything were up and running. So far, so good ... But, there are still some configuration issues I guess it would be better to understand and to fix: On server slave 1 and 2 - "Status display" shows "No network configured" (Screenshot #1) - "Display NICs" is empty, (despite everything seems to work) On server slave 2 + 'VMs running on this host' is empty (despite there ARE VMs running) + 'All VMs' displays "'NoneType' object has no attribute 'xenapi'" (Screenshot #2) Any suggestions ?

0 Tobias Kreidl Posted August 27, 2020 Share Posted August 27, 2020 For the server with no network, I'd try rebooting it a couple of times. If that fails, you'll need to do an emergency network reset back to a single primary management interface, and then see if it picks up the other network settings from the pool master (which obviously should be a different host). Some network settings, like iSCSI and NFS, will likely need to then ben manually reconfigured. -=Tobias Link to comment
0 Alan Lantz Posted August 28, 2020 Share Posted August 28, 2020 I wouldn't worry so much about the network not showing, I seem to remember some versions of XenServer having that issue. The VM's not showing is more troubling. Since its slaves with issues at least rebuilding is always a worst case scenario. I would try xe-toolstack-restart on the slaves and on the master in addition to xe-toolstack-restart I would do xe pool-recover-slaves to see if I could xe command get it to cooperate first. --Alan-- Link to comment

0 Alan Lantz Posted June 16, 2021 Share Posted June 16, 2021 Sounds like those slaves can't communicate with the master. Might want to try moving the master to another host to see if that clears up the issue. --Alan-- Link to comment
Question
Jeacuterocircme HAGUET
Hello
I have a XS 7.1CU2 pool with 3 servers.
Unfortunatly, we had a power failure 2 weeks ago.
On the first reboot, I was not able to contact the pool using XenCenter ...
Then, I have rebooted one by one each server, and I was able to contact the pool
I could restart all the VMs, and everything were up and running.
So far, so good ...
But, there are still some configuration issues I guess it would be better to understand and to fix:
On server slave 1 and 2
- "Status display" shows "No network configured" (Screenshot #1)
- "Display NICs" is empty, (despite everything seems to work)
On server slave 2
+ 'VMs running on this host' is empty (despite there ARE VMs running)
+ 'All VMs' displays "'NoneType' object has no attribute 'xenapi'" (Screenshot #2)
Any suggestions ?
