Joshua Boniface 254303b9d4 Use coordinator_state instead of router_state 
Makes it much clearer what this variable represents.

Joshua Boniface 40b7d68853 Separate monitoring and move to 60s interval 
Removes the dependency of the monitoring subsystem from the node
keepalives, and runs them at a 60s interval to avoid excessive backups
if a plugin takes too long.

Adds its own logs and related items as required.

Finally adds a new required argument to the run() of plugins, the
coordinator state, which can be used by a plugin to determine actions
based on whether the node is a primary, secondary, or non-coordinator.

Joshua Boniface b5f996febd Fix bugs for node flush for stop/shutdown/restart 
Previously VMs in stop/shutdown/restart states wouldn't be properly
handled during a node flush. This fixes the bugs and ensures that the
transient VM states (shutdown/restart) are completed before proceeding,
and then avoids setting a stopped/shutdown VM to shutdown/auotstart.

Joshua Boniface 38d63d9837 Flip behaviour of memory selectors 
It didn't make any sense to me for mem(prov) to be the default selector,
since this has too many caveats versus mem(free). Switch to using
mem(free) as the default (i.e. "mem") and make memprov the alternative.

Joshua Boniface 6c58d52fa1 Add node autoready oneshot unit 
This replicates some of the more important functionality of the defunct
pvc-flush.service unit. On presence of a trigger file (i.e.
/etc/pvc/autoready), it will trigger a "node ready" on boot. It does
nothing on shutdown as this must be handled by other mechanisms, though
a similar autoflush could be added as well.

longer. Use a proper conditional followed by an actual error handler.

Joshua Boniface ec559aec0d Remove pvc-flush service 
This service caused more headaches than it was worth, so remove it.

The original goal was to cleanly flush nodes on shutdown and unflush
them on startup, but this is tightly controlled by Ansible playbooks at
this point, and this is something best left to the Administrator and
their particular situation anyways.

Joshua Boniface 7a40c7a55b Add support for replacing/refreshing OSDs 
Adds commands to both replace an OSD disk, and refresh (reimport) an
existing OSD disk on a new node. This handles the cases where an OSD
disk should be replaced (either due to upgrades or failures) or where a
node is rebuilt in-place and an existing OSD must be re-imported to it.

This should avoid the need to do a full remove/add sequence for either
case.

Also cleans up some aspects of OSD removal that are identical between
methods (e.g. using safe-to-destroy and sleeping after stopping) and
fixes a bug if an OSD does not truly exist when the daemon starts up.
 2022-05-06 15:32:06 -04:00
Joshua Boniface 3801fcc07b Fix bug with initial JSON for stats 2022-05-02 13:28:19 -04:00
Joshua Boniface c741900baf Refactor OSD removal to use new ZK data 
With the OSD LVM information stored in Zookeeper, we can use this to
determine the actual block device to zap rather than relying on runtime
determination and guestimation.
 2022-05-02 12:52:22 -04:00
Joshua Boniface 464f0e0356 Store additional OSD information in ZK 
Ensures that information like the FSIDs and the OSD LVM volume are
stored in Zookeeper at creation time and updated at daemon start time
(to ensure the data is populated at least once, or if the /dev/sdX
path changes).

This will allow safer operation of OSD removals and the potential
implementation of re-activation after node replacements.
 2022-05-02 12:11:39 -04:00
Joshua Boniface cea8832f90 Ensure initial OSD stats is populated 
Values are all invalid but this ensures the client won't error out when
trying to show an OSD that has never checked in yet.

Joshua Boniface 4d698be34b Add OSD removal force option 
Ensures a removal can continue even in situations where some step(s)
might fail, for instance removing an obsolete OSD from a replaced node.

Joshua Boniface 00d2c67c41 Allow single-node clusters to restart and timeout 
Prevents a daemon from waiting forever to terminate if it is primary,
and avoids this entirely if there is only a single node in the cluster.
 2021-12-28 03:06:03 -05:00
Joshua Boniface 67131de4f6 Fix bug when removing OSDs 
Ensure the OSD is down as well as out or purge might fail.
 2021-12-28 03:05:34 -05:00
Joshua Boniface abc23ebb18 Handle detect strings as arguments for blockdevs 
Allows specifying blockdevs in the OSD and OSD-DB addition commands as
detect strings rather than actual block device paths. This provides
greater flexibility for automation with pvcbootstrapd (which originates
the concept of detect strings) and in general usage as well.

Joshua Boniface 8f906c1f81 Use power off in fence instead of reset 
Use a power off (and then make the power on a requirement) during a node
fence. Removes some potential ambiguity in the power state, since we
will know for certain if it is off.

Joshua Boniface 50d8aa0586 Add handlers for client network MTUs 
Refactors some of the code in VXNetworkInterface to handle MTUs in a
more streamlined fashion. Also fixes a bug whereby bridge client
networks were being explicitly given the cluster dev MTU which might not
be correct. Now adds support for this option explicitly in the configs,
and defaults to 1500 for safety (the standard Ethernet MTU).

Joshua Boniface f6f6f07488 Add timeouts to queue gets and adjust 
Ensure that all keepalive timeouts are set (prevent the queue.get()
actions from blocking forever) and set the thread timeouts to line up as
well. Everything here is thus limited to keepalive_interval seconds
(default 5s) to keep it uniform.

Joshua Boniface 55221b3d97 Simplify VM migration down to 3 steps 
Remove two superfluous synchronization steps which are not needed here,
since the exclusive lock handles that situation anyways.

Still does not fix the weird flush->unflush lock timeout bug, but is
better worked-around now due to the cancelling of the other wait freeing
this up and continuing.

Joshua Boniface 0d72798814 Work around synchronization lock issues 
Make the block on stage C only wait for 900 seconds (15 minutes) to
prevent indefinite blocking.

The issue comes if a VM is being received, and the current unflush is
cancelled for a flush. When this happens, this lock acquisition seems to
block for no obvious reason, and no other changes seem to affect it.
This is certainly some sort of locking bug within Kazoo but I can't
diagnose it as-is. Leave a TODO to look into this again in the future.
