Joshua Boniface c7c8c8bcbb Fix bug with flush 2019-07-10 00:43:55 -04:00
Joshua Boniface 7a8aee9fe7 Remove flush locking functionality
This just seemed like more trouble that it was worth. Flush locks were
originally intended as a way to counteract the weird issues around
flushing that were mostly fixed by the code refactoring, so this will
help test if those issues are truly gone. If not, will look into a
cleaner solution that doesn't result in unchangeable states.

Without this, the IPMI information set during initial node creation can
never be changed, which can cause issues later. Instead, always set it

Similar to recent client changes, don't replace the previous node record
of an already-migrated VM. Wait for shutdown if required. Use a

Joshua Boniface 0d398f663b Rename "Domain" to "VM" in various class names
The name "Domain", though technically correct from a Libvirt
perspective, was unnecessarily confusing. Call the class instances what
they are, VMs.

Joshua Boniface 8216125b02 Enable autostart of API client on Primary
Adds a config flag that turns on the API client following the Primary

Joshua Boniface 08cb16bfbc Revamp VM migration handling
This was very old code that was hard to follow and quite fragile, with
failures and infinite loops occurring fairly frequently. These changes
make the code more robust, including the addition of timeouts, some code
cleanup, and some improvements to the logical flow.

Also forces the libvirt migration to occur on the cluster network, which
couples to changes in the libvirtd listen (via pvc-ansible) and in
Daemon.py via the previous commit.

Joshua Boniface 75d0e7f989 Revert "Only perform fencing duties on primary"
This reverts commit 464c69aac6.

Actually, yea, this made sense - if the primary fails, it can't
fence itself.

Joshua Boniface 85a5a8a0c9 Disable tx offloading on bridge interfaces
Reference: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=717215#68

Without this, DHCP fails when traversing only the local bridge, for
Debian Jessie or earlier (and possibly other OSes as well), due to the
missing UDP checksums. This disables the offload and hence reenables
the checksums even on the software-only bridge.

Also rearranged the steps and added comments arround this section to
better clarify what each command is doing.

Joshua Boniface 464c69aac6 Only perform fencing duties on primary
There was really no need for this to be shared among all the
coordinators, which seemed more fragile. This way only the primary will
try to fence dead nodes.

Joshua Boniface 1d3f868206 Unify network devices and addresses in config
The old way of doing this was a little cumbersome, with an upper YAML
tree split between "devices" (name and MTU) and addresses. This commit
unifies these under the root "networking" section to make this section
clearer.

Joshua Boniface e70255dbd6 Support configurable interface MTUs
MTUs were hardcoded at 9000, which breaks if the underlying interface
or network switch does not support jumbo frames, a possible deployment
limitation. This has non-obvious consequences due to MTU mismatches
for certain services (Ceph, Zookeeper, etc.).

This commit adds support for configurable MTUs for each interface,
set in pvcd.yaml. The example has been updated to reflect this, with
a default of 1500 (the Ethernet standard).

This commit also adds autoconfiguration of the VNI device MTU based
on the `vni_mtu` value, the same for bridge networks and minus 50
(rather than 200 from the hardcoded value, based on the following
resource [1]) for VXLAN networks.

Joshua Boniface 7c6132f7dd Add node autoflush service and target
Add a systemd service to manage node flush/unflush, useful during
system startup and shutdown to avoid requiring administrator
intervention for this to occur. This is optional and the service is
not enabled by default, and the postinst script informs the
administrator of this.

Also adds a systemd target to collect the two service units together
and provide an easy way to flush+shutdown or startup+unflush the
entire PVC system.

Joshua Boniface 8ef21cf9f2 Sleep longer before removing gateways
1 second was just slightly too little time to wait and packets would

Joshua Boniface 3893666507 Improve performance by removing spurious actions
1. Remove a number of time.sleep commands which don't really seem
necessary any longer and which significantly increased the startup
time while parsing the VM list.
2. Handle some variable sets during initialization of the object,
rather than waiting for a management command, enabling...
3. Know when a state change, and the corresponding Libvirt lookup,
is unnecessary due to the target node not matching the current node.
This also removes a number of unremovable errors from Libvirt on the
console which were annoying.

This reduces the total time taken by the VM startup segment (lines
760-762 of Daemon.py) from 17.117s down to 0.976s for 82 VMs.

Joshua Boniface 595cf1782c Switch DNS aggregator to PostgreSQL
MariaDB+Galera was terribly unstable, with the cluster failing to
start or dying randomly, and generally seemed incredibly unsuitable
for an HA solution. This commit switches the DNS aggregator SQL
backend to PostgreSQL, implemented via Patroni HA.

It also manages the Patroni state, forcing the primary instance to
follow the PVC coordinator, such that the active DNS Aggregator
instance is always able to communicate read+write with the local
system.

This required some logic changes to how the DNS Aggregator worked,
specifically ensuring that database changes aren't attempted while
the instance isn't actively running - to be honest this was a bug
anyways that had just never been noticed.

Joshua Boniface 516ea1b57c Handle unflushes like flushes squentially
Makes an unflush a controlled event like flushing, rather than a

the locking to actually be effective.

Joshua Boniface c19902d952 Implement flush locking for nodes
Implements a locking mechanism to prevent clobbering of node
flushes. When a flush begins, a global cluster lock is placed
which is freed once the flush completes. While the lock is in place,
other flush events queue waiting for the lock to free before
proceeding.

Modifies the CLI output flow when the `--wait` option is specified.
First, if a lock exists when running the command, the message is
tweaked to indicate this, and the client will wait first for the
lock to free, and then for the flush as normal. Second, the wait
depends on the active lock rather than the domain_status for
consistency purposes.

Joshua Boniface b6ecd36588 Implement domain log watching
Implements the ability for a client to watch almost-live domain
console logs from the hypervisors. It does this using a deque-based
"tail -f" mechanism (with a configurable buffer per-VM) that watches
the domain console logfile in the (configurable) directory every
half-second. It then stores the current buffer in Zookeeper when
changed, where a client can then request it, either as a static piece
of text in the `less` pager, or via a similar "tail -f" functionality
implemented using fixed line splitting and comparison to provide a
generally-seamless output.

Enabling this feature requires each guest VM to implement a Libvirt
serial log and write its (text) console to it, for example using the
default logging directory:

```
<serial type='pty'>
    <log file='/var/log/libvirt/vmname.log' append='off'/>
<serial>
```

The append mode can be either on or off; on grows files unbounded,
off causes the log (and hence the PVC log data) to be truncated on
initial VM startup from offline. The administrator must choose how
they best want to handle this until Libvirt implements their own
clog-type logging format.

Joshua Boniface 1f58d61cb0 Rewrite DNSAggregatorInstance to handle DNS well
Trying to directly AXFR from dnsmasq is a mess, since their zone is
barely compliant with spec, it doesn't support notifies, and it is
generally really messy.

This implements an advanced "AXFR parser" system, which looks at the
results of an AXFR from the local dnsmasq instances per-network, and
updates the real replicated MariaDB pdns backend cluster with the
changed data. This allows a sensible, transferable zone with its own
SOA that is dynamically reconfigured as hosts come and go from the
dnsmasq zone.
