Joshua Boniface b770e15a91 Fix final termination of logger
We need to do a bit more finagling with the logger on termination to
ensure that all messages are written and the queue drained before
actually terminating.

Joshua Boniface 323c7c41ae Implement node logging into Zookeeper
Adds the ability to send node daemon logs to Zookeeper to facilitate a
command like "pvc node log", similar to "pvc vm log". Each node stores
its logs in a separate tree under "/logs" which can then be combined or
queried. By default, set by config, only 2000 lines are kept.

Joshua Boniface 20b66c10e1 Move two more commands to Rados library 2021-07-10 17:28:42 -04:00
Joshua Boniface cfeba50b17 Revert "Return to all command-based Ceph gathering"
This reverts commit 65d14ccd92.

This was actually a bad idea. For inexplicable reasons, running these
Ceph commands manually (not even via Python, but in a normal shell)
takes 7 * two orders of magnitude longer than running them with the
Rados module, so long in fact that some basic commands like "ceph
health" would sometimes take longer than the 1 second timeout to
complete. The Rados commands would however take about 1ms instead.

Despite the occasional issues when monitors drop out, the Rados module
is clearly far superior to the shell commands for any moderately-loaded
Ceph cluster. We can look into solving timeouts another way (perhaps
with Processes instead of Threads) at a later time.

Rados module "ceph health":
    b'{"checks":{},"status":"HEALTH_OK"}'
    0.001204 (s)
    b'{"checks":{},"status":"HEALTH_OK"}'
    0.001258 (s)
Command "ceph health":
    joshua@hv1.c.bonilan.net ~ $ time ceph health >/dev/null
    real    0m0.772s
    user    0m0.707s
    sys     0m0.046s
    joshua@hv1.c.bonilan.net ~ $ time ceph health >/dev/null
    real    0m0.796s
    user    0m0.728s
    sys     0m0.054s

Joshua Boniface 65d14ccd92 Return to all command-based Ceph gathering
Using the Rados module was very problematic, specifically because it had
no sensible timeout parameters and thus would hang for many seconds.
This has poor implications since it blocks further keepalives.

Instead, remove the Rados usage entirely and go back completely to using
manual OS commands to gather this information. While this may cause PID
exhaustion more quickly it's worthwhile to avoid failure scenarios when
Ceph stats time out.

Closes #137

Joshua Boniface 5607a6bb62 Avoid overwriting VF data
Ensures that the configuration of a VF is not overwritten in Zookeeper
on a node restart. The SRIOVVFInstance handlers were modified to start
with None values, so that the DataWatch statements will always trigger
updates to the live system interfaces on daemon startup, thus ensuring
that the config stored in Zookeeper is applied to the system on startup
(mostly relevant after a cold boot or if the API changes them during a
daemon restart).

Joshua Boniface e7b6a3eac1 Implement SR-IOV PF and VF instances
Adds support for the node daemon managing SR-IOV PF and VF instances.

PFs are added to Zookeeper automatically based on the config at startup
during network configuration, and are otherwise completely static. PFs
are automatically removed from Zookeeper, along with all coresponding
VFs, should the PF phy device be removed from the configuration.

VFs are configured based on the (autocreated) VFs of each PF device,
added to Zookeeper, and then a new class instance, SRIOVVFInstance, is
used to watch them for configuration changes. This will enable the
runtime management of VF settings by the API. The set of keys ensures
that both configuration and details of the NIC can be tracked.

Most keys are self-explanatory, especially for PFs and the basic keys
for VFs. The configuration tree is also self-explanatory, being based
entirely on the options available in the `ip link set {dev} vf` command.

Two additional keys are also present: `used` and `used_by`, which will
be able to track the (boolean) state of usage, as well as the VM that
uses a given VIF. Since the VM side implementation will support both
macvtap and direct "hostdev" assignments, this will ensure that this
state can be tracked on both the VF and the VM side.

Joshua Boniface 0a9c0c1ccb Use a nicer reload method on hot schema update
Instead of exiting and trusting systemd to restart us, instead leverage
the os.execv() call to reload the process in the current PID context.

Also improves the log messages so it's very clear what's going on.
2021-06-14 17:10:21 -04:00
Joshua Boniface e34a7d4d2a Handle hot reloads properly
A hot reload isn't possible due to DataWatch and ChildrenWatch
constructs, so we instead need to terminate the daemon to "apply" the
schema update. Thus we use exit code 150 (Application defined in LSB)
and reorder some of the elements of the schema validation to ensure
things happen in the right order.
