Joshua Boniface e76832de91 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 04ca8f73d2 Correct bugs during bootstrap
1. Ensure Zookeeper restarts and checks out successfully before
proceeding with other steps.
2. Make sure PVC itself doesn't start prematurely.

Joshua Boniface de04105a38 Add tuning for Ceph OSDs 2020-12-21 00:20:45 -05:00
Joshua Boniface 28c86d170f Don't use libjemalloc for Ceph daemons
This was an artifact of a much, much older Ceph configuration I ran, and
is not relevant with newer Ceph versions like those used in PVC.
Performance testing with Nautilus and Bluestore reveals a minimal
performance hit, and using `jemalloc` prevents cache autotuning from
being effective, so remove it.

Joshua Boniface cb96ef4e7a Use new init command location
Command was renamed in the PVC CLI to facilitate other "task" actions
like backup/restore.

Joshua Boniface 3c0c3e8e56 Add jute.maxbuffer to Zookeeper environment ops
Adds this option based on the findings of
https://github.com/python-zk/kazoo/issues/630, whereby restores of >1MB
in size would fail. This is considered an unsafe option, but given our
usecase no actual znode should ever exceed this limit; this is purely
for the large transactions that come from a `pvc task restore` action to
an empty Zookeeper instance.

Joshua Boniface 934f73af0f Support using existing SSL certs on system
Add the additional pvc_api_ssl_cert_path and pvc_api_ssl_key_path
group_vars options, which can be used to set the SSL details to existing
files on the filesystem if desired. If these are empty (or nonexistent),
the original pvc_api_ssl_cert and pvc_api_ssl_key raw format options
will be used as they were.

Allows the administrator to use outside methods (such as Let's Encrypt)
to obtain the certs locally on the system, avoiding changes to the
group_vars and redeployment to manage SSL keys.

use it instead.
