Joshua Boniface f030ed974c Correct schema and handling of network subkeys 
Required a bit of refactoring in the validation code to ensure we have
direct access, without relying on the translations done in the normal
zkhandler functions.

Joshua Boniface 5540bdc86b Add automatic schema upgrade to nodes 
Performs an automatic schema upgrade when all nodes are updated to the
latest version.

Joshua Boniface 3c102b3769 Add per-node schema tracking 
This will allow nodes to start with their own schema versions, and then
be updated simultaneously by the API.

 2021-06-08 23:35:39 -04:00
Joshua Boniface 126f0742cd Add Zookeeper schema manager to zkhandler 
Adds a new class, ZKSchema, to handle schema management in Zookeeper in
an automated and consistent way. This should solve several issues:

1. Pain in managing changes to ZK keys
2. Pain in handling those changes during live upgrades
3. Simplifying the codebase to remove hardcoded ZK paths

The current master schema for PVC 0.9.19 is committed as version 0.

Addresses #129

Joshua Boniface f0dc0fc782 Avoid duplicating maintenance state change 
This makes no functional difference, but is technically more correct.
 2021-06-05 01:36:40 -04:00
Joshua Boniface 5d88e92acc Avoid returning errors with duplicate router mode 
Like the previous (new) flush change, these shouldn't be errors, but
simply information "what you want is already done" messages.

Joshua Boniface a48bf2d71e More gracefully handle none selectors 
Allow selection of "none" as the node selector, and handle this by

Joshua Boniface 8c4c1aba38 Revert "Add object-map to default RBD volume features" 
This reverts commit 00e9cca6f0.

This causes RBD mapping to fail on Debian 10. Reverting but keeping in
history for future reference.
 2021-02-28 01:57:30 -05:00
Joshua Boniface 00e9cca6f0 Add object-map to default RBD volume features 
This allows for much quicker image deletes especially for empty images.
 2021-02-17 13:57:28 -05:00
Joshua Boniface ab05e0f3db Add B suffix back to bare bytes values 2021-02-17 11:37:36 -05:00
Joshua Boniface 9291ce6ffc Correct output of fromhuman and add size compare 
Ensures that the bytes_tohuman returns an integer to avoid the hacky
workaround of stripping off the B.

Adds a verification on the size of a new volume, that it is not larger
than the free space of the pool to prevent errors/excessively-large
volumes from being created.

Closes #120
