Joshua Boniface cba6f5be48 Fix wording of non-coordinator state 2023-09-15 16:51:04 -04:00
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.

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.

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.

Joshua Boniface cea8832f90 Ensure initial OSD stats is populated
Values are all invalid but this ensures the client won't error out when

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.
