Joshua Boniface ac36870a86 Implement hup for log rotation 
This function was long-existent, but never used; implement it.

Joshua Boniface 58f4222ee7 Support disabling log colours and dates 
For usecases such as a pure-syslog, allow disabling of dates or colours
in the log messages (separately).

Joshua Boniface 0d513fea4d Add delay after deleting VM 
Otherwise there might still be a watcher on the block device when we go
to delete it, which causes a failure.

Joshua Boniface 13d13b75d7 Revert "Add material theme to docs" 
This reverts commit e9dcbf6198.

ReadTheDocs really doesn't like this theme, so forget that idea.

This reverts commit ec3507db1e.
 2019-07-10 15:23:15 -04:00
Joshua Boniface ec3507db1e Use null name for material theme 
With a real name, RTD complains.

Joshua Boniface 9ccf3390ab Add storage prefix to Ceph commands 
Add the "storage" prefix to all Ceph-based commands in both the CLI and
the API. This partially abstracts the storage subsystem from the Ceph
tool specifically, should future storage subsystems be added or changed.
The name "ceph" is still used due to the non-abstracted components of
the Ceph management, e.g. referencing Ceph-specific concepts like OSDs
or pools.

Joshua Boniface 8a28738bff Use consistent terminology in fence message 2019-07-10 11:54:56 -04:00
Joshua Boniface 8f160abf90 Handle cancelling flushes when new ones run 
Store the flush_thread of a node as a class object. Before starting a
new flush thread (either flush or unflush), stop the existing one if it
exists to prevent further migrations, then start the new thread. Set the
object to None on init and again once the task actually finishes. Remove
the inflush flag as this is not required when using these threads and
functionally does nothing any longer, but add the flush_stopper flag to
trigger cancellation of the current job.

Joshua Boniface c7c8c8bcbb Fix bug with flush 2019-07-10 00:43:55 -04:00
Joshua Boniface 7a8aee9fe7 Remove flush locking functionality 
This just seemed like more trouble that it was worth. Flush locks were
originally intended as a way to counteract the weird issues around
flushing that were mostly fixed by the code refactoring, so this will
help test if those issues are truly gone. If not, will look into a
cleaner solution that doesn't result in unchangeable states.

Joshua Boniface 47f86475f8 Handle failures of Ceph commands gradefully 
If these commands fail, catch the error, print a message, and set up
empty lists. Also handle later data parsing in this case.

Joshua Boniface 4249d5d982 Always load and store IPMI on daemon start 
Without this, the IPMI information set during initial node creation can
never be changed, which can cause issues later. Instead, always set it
fresh on each node boot.

Joshua Boniface 6426607769 Store list of RBD disks in ZK 
Store a basic list of RBD disks in Zookeeper for access by the node
subsystem to handle RBD locks. This avoids the need to implement complex
parsing logic inside the fencing configuration (or elsewhere).

Also handle a malformed XML content properly during VM define.
