Joshua Boniface bc38af774e Check that node is in run state before primary 
Fixes #37
 2019-06-19 12:49:34 -04:00
Joshua Boniface 9a0554fdbe Remove all volumes from pool on removal 
Technically not needed, but otherwise random errors may be thrown,
so best to be explicit.

Joshua Boniface 87907d4ce8 Remove size field from volume objects 
This data is just in the stats anyways.

Joshua Boniface db0b382b3d Don't bother with snapshot management by Daemon 
This is *definitely* not needed in the end, and just uses RAM for
no conceivable purpose. Snapshots are fully client-managed.

Joshua Boniface 98365b0fcf Correct bugs around snapshots 2019-06-19 09:41:33 -04:00
Joshua Boniface 1c9f606480 Implement volume and snapshot handling by daemon 
This seems like a super-gross way to do this, but at the moment
I don't have a better way. Maybe just remove this component since
none of the volume/snapshot stuff is dynamic; will see as this
progresses.

Joshua Boniface 01959cb9e3 Implementation of RBD volumes and snapshots 
Adds the ability to manage RBD volumes (add/remove) and RBD
snapshots (add/remove). (Working) list functions to come.

Joshua Boniface b50b2a827b Add forced delays after pool add/remove 
Prevents returning immediately to give the cluster some breathing
room before the admin can do other commands. Keep the write lock
as well to prevent other clients from attempting this as well.

Joshua Boniface b0411e8e1a Remove "error" message from Ceph commands 
This triggeres at every node start and isn't useful.

Joshua Boniface 8d9007f697 Remove OSD stat collection if count is zero 
Otherwise, ceph osd df will hang indefinitely trying to get data
for the zero OSDs.

Joshua Boniface d4ebe63d9b Rename network device field 
It seems much nicer and more consistent as "device" rather than as
"name".
 2019-06-17 23:44:41 -04:00
Joshua Boniface 1d3f868206 Unify network devices and addresses in config 
The old way of doing this was a little cumbersome, with an upper YAML
tree split between "devices" (name and MTU) and addresses. This commit
unifies these under the root "networking" section to make this section
clearer.

Joshua Boniface e70255dbd6 Support configurable interface MTUs 
MTUs were hardcoded at 9000, which breaks if the underlying interface
or network switch does not support jumbo frames, a possible deployment
limitation. This has non-obvious consequences due to MTU mismatches
for certain services (Ceph, Zookeeper, etc.).

This commit adds support for configurable MTUs for each interface,
set in pvcd.yaml. The example has been updated to reflect this, with
a default of 1500 (the Ethernet standard).

This commit also adds autoconfiguration of the VNI device MTU based
on the `vni_mtu` value, the same for bridge networks and minus 50
(rather than 200 from the hardcoded value, based on the following
resource [1]) for VXLAN networks.

Joshua Boniface c583ee1709 Revert "Wait a little longer" 
This reverts commit bd7a55e9e1.

This is not really needed, but do keep the 5s wait
 2019-06-17 21:56:06 -04:00
Joshua Boniface bd7a55e9e1 Wait a little longer 2019-06-17 12:14:13 -04:00

Joshua Boniface fe654aa5a2 Correct typo in daemon 2019-06-16 19:27:20 -04:00
Joshua Boniface 3ba3c339a7 Show vCPU count on CLI output 
Showing the static, total number of CPUs was pointless. Instead,
show the number of allocated vCPUs. To preserve space, no longer
show the host CPU count in the list.

Joshua Boniface 14e9ba892c Wait on both sides for 30s 
Still finding issues with the flush
 2019-05-24 01:23:18 -04:00
Joshua Boniface 703e34e8ea Remove disable of pvc-flush 
Since it isn't re-enabled and this makes life difficult, don't
disable the pvc-flush service if it was enabled.
 2019-05-23 23:47:57 -04:00
Joshua Boniface ae37afcf75 Wait 10 seconds when starting pvc-flush 
Without waiting the unflush will trigger too soon, before the
daemon is fully ready and such it fails in odd ways.

Joshua Boniface e8b666708c Add one final keepalive update before exiting 2019-05-23 23:23:03 -04:00
Joshua Boniface 4c5ce9b995 Perform additional tweaks to units 
Use RemainAfterExit to avoid pvc-flush from auto-stopping immediately.

Use PartOf to tie services to the target itself.

Use --wait on flush to avoid daemon stopping before flush is complete.
