Adds in three parts:
1. Create an API endpoint to create OSD DB volume groups on a device.
Passed through to the node via the same command pipeline as
creating/removing OSDs, and creates a volume group with a fixed name
(osd-db).
2. Adds API support for specifying whether or not to use this DB volume
group when creating a new OSD via the "ext_db" flag. Naming and sizing
is fixed for simplicity and based on Ceph recommendations (5% of OSD
size). The Zookeeper schema tracks the block device to use during
removal.
3. Adds CLI support for the new and modified API endpoints, as well as
displaying the block device and DB block device in the OSD list.
While I debated supporting adding a DB device to an existing OSD, in
practice this ended up being a very complex operation involving stopping
the OSD and setting some options, so this is not supported; this can be
specified during OSD creation only.
Closes#142
Adds a new API endpoint to support hot attach/detach of devices, and the
corresponding client-side logic to use this endpoint when doing VM
network/storage add/remove actions.
The live attach is now the default behaviour for these types of
additions and removals, and can be disabled if needed.
Closes#141
Before, "-y"/"--yes" only confirmed the reboot portion. Instead, modify
this to confirm both the diff portion and the restart portion, and add
separate flags to bypass one or the other independently, ensuring the
administrator has lots of flexibility. UNSAFE mode implies "-y" so both
would be auto-confirmed if that option is set.
Add an additional protected class, limit manipulation to one at a time,
and ensure future flexibility. Also makes display consistent with other
VM elements.
Matches the new node list output format with the additional header line,
as well as revamps some other aspects:
1. Adjusts the UUID to be under the name in the info output.
2. Removes the UUID from the list output to save space, because this
is generally not needed in day-to-day quick-list output.
3. Renames the "Node" header to "Current" to better reflect what
that column actually means and avoid conflicting with the parent
header.
Also adjusts the layout of the node list output to avoid excessively
long lines. Adds another header line with categories and spacing dashes
for easier visual parsing.
Also fixes up the Debian packaging such that this works how I would
want, with proper module installation while leaving everything else
untouched. Finally implements automatic installation and removal of the
BASH completion for the PVC command.
For the "vm modify", revamp the way confirmations are presented. Do the
edits/load, show changes, verify XML, then prompt to write and the
restart. The previous order didn't make much sense.
For any of these `--restart` triggered VM modifications, also alter how
the confirmation works. If the user declines the restart, do not abort;
instead, just set restart=False and continue with the modification.
Allows another way (beyond --yes) to avoid confirming "unsafe"
operations. While there is probably nearly zero usecase for this (at
least to any sane admin), it is provided to allow maximum flexibility.
Sets in the node daemon, returns via the API, and shows in the CLI,
information about the live VNC listen address and port for VNC-enabled
VMs.
Closes#115
Adds cluster backup (JSON dump) and restore functions for use in
disaster recovery.
Further, adds additional confirmation to the initialization (as well as
restore) endpoints to avoid accidental triggering, and also groups the
init, backup, and restore commands in the CLI into a new "task"
subsection.
Before, the default False was problematic and would reset consoles if
the template was otherwise modified. Instead switch the flags to be full
true/false flags, and on modify, adjust the default to be None so they
will not be changed.
