Joshua Boniface dd0177ce10 Rework replacement procedure again
Avoid calling other functions; replicate the actual process from Ceph
docs (https://docs.ceph.com/en/pacific/rados/operations/add-or-rm-osds/)
to ensure things work out well (e.g. preserving OSD IDs).

Joshua Boniface 64e37ae963 Update OSD replacement functionality
1. Simplify this by leveraging the existing remove_osd/add_osd
functions, since its task was functionally identical to those two in
sequential order.
2. Add support for split OSDs within the command (replacing all OSDs on
the block device(s) as required).
3. Add additional configurability and flexibility around the old device,
weight, and external DB LVs.

Joshua Boniface 526a5f4a74 Add support for split OSD adds
Allows creating multiple OSDs on a single (NVMe) block device,
leveraging the "ceph-volume lvm batch" command. Replaces the previous
method of creating OSDs.

Also adds a new ZK item for each OSD indicating if it is split or not.

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.

Also removes several outputs from the normal keepalive that were
superfluous/static so that the main output fits on one line.

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 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.

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 67131de4f6 Fix bug when removing OSDs
Ensure the OSD is down as well as out or purge might fail.

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.
