Joshua Boniface 0ad6d55dff Add initial SR-IOV support to node daemon 
Adds configuration values for enabled flag and SR-IOV devices to the
configuration and sets up the initial SR-IOV configuration on daemon
startup (inserting the module, configuring the VF count, etc.).

Joshua Boniface e4a65230a1 Just do the shutdown command itself 2021-06-15 02:32:14 -04:00
Joshua Boniface 284c581845 Ensure shutdown migrations actually time out 
Without this a VM that fails to respond to a shutdown will just spin
forever, blocking state changes.

non-primary coordinators.

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.

Joshua Boniface ac3ef3d792 Revamp fencing order

before, would have to go through 3 timed out commands at ~20s each
before failure was registered; reduced to 1 if the first times out.

Joshua Boniface 3705daff43 Better handle failing RBD lock frees 
If the VM is not in a stop state, failing to free the lock is now
considered a fatal error and will put the domain into fail state,
aborting the start. This is better than being unsafe or trying to start
a VM which will fail to boot due to read-only volumes.

Joshua Boniface 7c99a7bda7 Safely reset RBD locks on failed VMs 
Should correct issues on cold start as well as if a VM crashes
uncleanly, which would prevent the VM from starting due to stale RBD
locks.

This implementation has four parts:
  1. Update how IP addresses are handled, specifically by replacing all
  previous instances of "vni_ipaddr" with "vni_floatingipaddr", and then
  adding the "vni_ipaddr" with the real data for this node's IPs. Also
  include the storage IPs in this where they weren't before, so each
  this_node actually has the local IPs plus floating IPs. This enables
  the next two steps.
  2. Modify flush_locks to take this_node as an argument, and update the
  run_command function to only operate against this node, rather than on
  the primary coordinator.
  3. Have the flush_locks check each lock against the current node, to
  verify that the lock is actually held by the current node. This is the
  only way to do this safely. During fencing, we override this by not
  passing a this_node which bypasses this check.
  4. Have the VM start do the check for VM failure/startup and execute a
  flush_locks before actually starting the VM.

Joshua Boniface 89c7e225a0 Move OSD stats uploading to primary only 
Instead of each node uploading its own OSD stats, which would not work
if the PVC daemon wasn't running, instead have the primary upload stats
for all OSDs in the cluster.
