Joshua Boniface 8d0f26ff7a Add additional kb_ values to OSD stats 
Allows for easier parsing later to get e.g. % values and more details on
the used amounts.

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 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 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.

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.

Validation already happened and the set happens again later.

Joshua Boniface fe73dfbdc9 Use current live value for bridge_mtu 
This will ensure that upgrading without the bridge_mtu config key set
will keep things as they are.

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 3122d73bf5 Avoid duplicate runs of MTU set 
It wasn't the validator duplicating, but the update duplicating, so
avoid that happening properly this time.

Joshua Boniface 7ed8ef179c Revert "Avoid duplicate runs of MTU validator"

Joshua Boniface caead02b2a Set all log messages to information state 
None of these were "success" messages and thus shouldn't have been ok
state.
