Joshua Boniface 30ddeb0fee Update MOTD automatically on boot 
The cron every minute was pointlessly excessive considering this doesn't
actually change minute-to-minute.

Joshua Boniface 86026de8ef Adjust colour scheme of MOTD 2023-09-01 15:42:29 -04:00
Joshua Boniface 8e1d005d43 Obtain more information for MOTD header 
Add model and serial numbers to the vendor, and put this on its own
line. Also use BASH for proper syntax formatting. Reformat the header to
be a more compact format.

Joshua Boniface 95b47f8b09 Fix a few more extraneous splits 
Just use this_node if applicable, or the raw node.hostname.
 2023-09-01 15:42:28 -04:00
Joshua Boniface d24cb8a8ef Unify and standardize inventory_hostname 
This was causing some confusing conflicts, so create a new fact called
"this_node" which is inventory_hostname.split('.')[0], i.e. the short
name, and use that everywhere instead of an FQDN or true inventory
hostname.

Joshua Boniface 056c325486 Add option for setting CPU governor 
Allows the administrator to set a CPU frequency governor if they need
to, though the default of ondemand is usually sufficient.

Joshua Boniface 7c7ca4a229 Allow inter-cluster orphan NTP sync 
Due to the requirement of Ceph to have all peer nodes tightly
synchronized with each other to come online, PVC nodes need a way to
synchronize to each other even in the absence of an external time
reference. This is especially prevalent if a set of nodes are left
offline for an extended period (>1-2 weeks), since their hardware clocks
will drift. If the resulting Internet connectivity is then dependent on
a VM, this will cause a catch-22 and the cluster will not properly
start.

This configuration will accomplish that - if no suitable >6 stratum
peers are found, the hosts will enter orphan mode. Since they are now
all configured as "peers" with each other, they will collectively decide
on one of them to become the source and sync to it. A local stratum 10
fudge is added so that at least one of the nodes can become this source.

While this is not an ideal use of NTP, it is by far the cleanest
solution to this problem, and does not impact normal functionality when
the two configured stratum-2 servers are reachable.

Joshua Boniface 88209a2b70 Use Google DNS instead of Cloudflare 
For some reason Cloudflare works in fewer places than Google, so just
use it instead.

Joshua Boniface fbbf5ffe09 Use cluster_group variable for paths 
Instead of trying to automagic this group out of the Ansible hostvars,
