@julien-f is aware of this problem and we'll find a way to make it more obvious

@Danp I tried some of the xe commands listed in that post like xe vm-param-clear and xe vm-param-remove and wasn't successful.

@tuxpowered said in Rolling Pool Update - host took too long to restart: When the first note reboots (the master), I can see that the system is back up in 5-8 min. If I go in to XO > Settings > Servers and click the Enable/Disable status button to reconnect it pops right up. Again, does not resume migrating the other nodes. That is what I am seeing also, logged here https://xcp-ng.org/forum/topic/9683/rolling-pool-update-incomplete

@Gheppy A follow up... Patches appeared in XO right after updating the files (prior to an XCP-ng reboot). Just FYI.

@olivierlambert Ah, ok...thanks, but I'm not using the appliance; I installed XO via source.

@julien-f @julien-f All I have done is let ronivay's script do the builds daily on schedule if there is a new commit on the master branch. His script has not changed. There have been no new patches to the hosts. I don't have an explanation.

Trying something new... Remove all servers from XO and log out. Host 1 is powered off. On host 2. xe task-list uuid ( RO) : 727ecb6b-6f2e-15eb-601b-110b2478996b name-label ( RO): Async.host.power_on name-description ( RO): status ( RO): pending progress ( RO): 0.000 xe task-cancel uuid=727ecb6b-6f2e-15eb-601b-110b2478996b Task is still there. From XCP-NG Center. Shutdown all VMs and host2 (All powered off). Powered up both servers. Wait 15 minutes to make sure no tasks are pending (xe task-list). Logging output to file via putty of; tail -f /var/log/audit.log Added host2 (master) to XO Settings/Servers. The Async.host.power_on task hasn't come back.
