<br>
There are a couple of ways we do these transitions.<br>
<br>
1) Spin up a new virtual machine with an incremented hostname:<br>
Example:<br>
a) check to see which ask systems exist. (ask01, ask02)<br>
b) create a new virtual machine with an incremented number: ask03<br>
c) ansible the system to be clone of ask01<br>
d) either turn off ask01 and rename ask03 to be ask01<br>
OR<br>
d) configure other servers to point to ask03 instead of ask01<br>
e) fix problems as needed<br>
f) shutdown and remove ask01.<br>
<br>
2) Move virtual machine to another server.<br>
a) Schedule a downtime<br>
b) Shutdown the server<br>
c) network dd the lvm image to other server.<br>
d) copy over the /etc/libvirt/qemu/___.xml file over to other server.<br>
e) spin up server<br>
f) fix problems as needed<br>
g) remove files from old server<br>
<br>
3) If the image is on an iscsi share versus local disks...<br>
a) shutdown the image on server A.<br>
b) copy the xml files over to server B.<br>
c) get libvirt to see them.<br>
d) start the image on server B<br>
e) remove the xml files from server A.<br>
<br>
It looks like none of the servers in question are on the iscsi share<br>
so we won't be able to do 3. [Unless there is one or two that are good<br>
candidates to be on the iscsi share... then a variant of 2 would be<br>
used.]<br>
<br>
Downtimes except for the fas system will be in the 20 minute range.<br>
The fas database might be 1-3 hours due to a 100 GB image to be copied<br>
over and the usual 'what we have to reboot that because this was down?<br>
WHY?' problems we end up with.<br>
<br>
Other plans and ideas can be replied to here.<br>
