s/rebooting/rebooted
Apologies for the miswording on my end.
Please be careful of tenses (past tense etc), as it will change the meaning of the question and thus the answer. As rebooted can be understood as it has already completed rebooting the host, following the update reboot request.

Yeah... I was trying to be helpful, but I was clearly in too much of a hurry.
Mea culpa

It’s alright great that you’re willing to help even during your own time. I posted what I did in order to help you get better with the English language.
Next time you think you’re in too much of a hurry say to yourself or in your mind, this old saying “Haste makes waste”.

Mystery solved:
There are numerous hosts under one master in the pool. I ran the yum update command on the master first, then rebooted, I then ran yum update on the rest and rebooted all but one. I could not reboot the last one until this morning (Saturday).I rebooted the last one a few minutes ago and all is well.
Because I think its interesting, I'd love someone smart to explain the process of why other hosts could not do a snapshot because a different host in the pool had not been rebooted.

Because doing an update without rebooting doesn't reload the updated main programs, like XAPI. A host in only updated after a full reboot.

Hi there
Is it just me or is this a chicken and egg situation.you upgrade the master... how the pool is in NOT_SUPPORTED_DURING_UPGRADE() stage. You cant move vms off the master so all you can do is close down vms.. reboot.. pray
then move the a non master.. you cant move the vms off here either NOT_SUPPORTED_DURING_UPGRADE(). So you have do the same..
needless to say I hit issues on each reboot which caused 30- 60 min delays in getting vms back up and running.
can you Warm migrate or is this dead also (to scared to test)

For me this workflow worked every time there were upgrades available:
-disable HA on pool level
-disable load balancer plugin
-upgrade master
-upgrade all other nodes
-restart toolstack on master
-restart toolstack on all other nodes
-live migrate all VMs running on master to other node(s)
-reboot master
-reboot next node (live migrate all VMs running on that particular node away before doing so)
-repeat until all nodes have been rebooted (one node at a time)
-re-enable HA on pool level
-re-enable load balancer pluginNever had any issues with that. No downtime for none of the VMs.

Exactly and that's what does the Rolling Pool Update feature

As an observation ; I'm going to draw attention to @majorp93's point about rebooting the servers after ALL nodes have been upgraded.
Historically we would move all VMs off master, upgrade master, restart its toolstack, then reboot master, then move VMs from Node 1 to master so we could begin the upgrade on Node1. Normally works ok but last time around it caused all sorts of problems. Previously it had felt right to upgrade master in its entirety including the reboot before moving on to the next host and rinse, repeat - but this cost us a lot of time, corruptions and pain.
TLDR: Perhaps add a footnote to the docs that when upgrading a pool the reboots should take place as a final step across the pool only after all nodes have been updated.
