If there is...
1. No '--cluster' passed, and
2. No 'local' cluster, and
3. There is exactly one cluster configured
...then use that cluster by default in the CLI.
Allows an administrator to adjust the PG count of a given pool. This can
be used to increase the PGs (for example after adding more OSDs) or
decrease it (to remove OSDs, reduce CPU load, etc.).
Allows specifying a particular device class ("tier") for a given pool,
for instance SSD-only or NVMe-only. This is implemented with Crush
rules on the Ceph side, and via an additional new key in the pool
Zookeeper schema which is defaulted to "default".
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.
This ensures that any client command is logged by the local system.
Helps ensure Accounting for users of the CLI. Currently logs the full
command executed along with the $USER environment variable contents.
This is recommended by the Python Requests documentation:
> It’s a good practice to set connect timeouts to slightly larger than a
multiple of 3, which is the default TCP packet retransmission window.
This allows us to keep a very low connect timeout of 3 seconds, but also
ensure that long commands (e.g. --wait or VM disable) can take as long
as the API requires to complete.
Avoids having to explicitly set very long single-instance timeouts for
other functions which would block forever on an unreachable API.
Allows preserving colour within e.g. watch, where Click would normally
determine that it is "not a terminal". This is done via the wrapper echo
which filters via the local config.
Instead of erroring, just use the implication that restarting a VM does
not want a live modification, and proceed from there. Update the help
text to match.
When using the "state", "node", or "tag" arguments to a VM list, add
support for a "negate" flag to look for all VMs *not in* the state,
node, or tag state.
