As stated in the ha-manager #2 patch, I'm inclined to register this at
/nodes/{node}/ha/... instead of /cluster/ha/nodes/{nodes}/..., because
then we wouldn't need to duplicate the nodelist in the HA endpoints in
the latter, because it is already provided at GET /nodes. We could still
provide information on GET /nodes/{node}/ha for each node, e.g. the LRM
state, mode, etc.

Just to be sure: do you mean for "each"–as in separately for the respective
node–or for "all"–as in always for all nodes independent on which {node}?
The latter should rather be returned by /cluster/resources, if needed.

AFAICT the informational endpoints might not be needed anymore for this
patch series anyway (as the lrm_mode is now returned by the HA's status
endpoint), but I meant the former case where GET /nodes/{node}/ha would
have returned the {node}'s LRM state, mode, etc.

On second thought, most users would probably like to know about the
status of all LRMs at once instead of needing to do one-by-one requests,
but that's what GET /cluster/ha/status/current is already here for.

s/pane/panel/?

I understand that pane might be more correct here, but I'd guess that
users are more familiar with 'panel' here.

Also, I think it would be nicer to integrate that into the former
sentence, for example:

Currently you can enabled or disable the maintenance mode in the HA
status panel in the web UI or using the ha-manager CLI tool.

Yep, that makes sense to me. Will fix up for a v2 patch.

I actually meant for that one to be gone and replaced with the added
sentence instead. I must've missed the removal on my local branch
patch application. Is the replacement sentence okay or should it be
removed and the existing sentence updated?

Ah I see, then both are fine even though I'd replace the 'using the
buttons on the HA panel' with just 'in the HA status panel' as you
describe how it's done later already, but that's just nit-picking on my
side ;-).

Why use two packages in this file here? AFAICT this seems like it is
copy-pasted from PVE::API2::Nodes and could very well be a single
package as that's much cleaner than having two packages in one file.

Also it seems like we do that seldomly:

# rg -o -c -g "*.pm" "^package" . | awk -F: '{if ($2 > 1){print $1}}'

are extract_param, cfs_{read,write}_file, dclone used?

nit: either way, use statements should follow the dependencies style
guide [1], i.e. something like the following:


use HTTP::Status qw(:constants);
use Storable qw(dclone);

use PVE::Cluster qw(cfs_read_file cfs_write_file);
use PVE::JSONSchema qw(get_standard_option);
use PVE::RPCEnvironment;
use PVE::SafeSyslog;
use PVE::Tools qw(extract_param);

use PVE::HA::Config;

Hm, we do that differently around the API endpoints, but at least for
the HA-related API endpoints we don't list the subdirectories, but
output the information in the entity itself, e.g. for HA resources:


+ ha
|
+-+ resources     - GET    List HA resources.
  +               - POST   Create a new HA resource.
  |
  +-+ {sid}       - GET    Read resource configuration.
    +             - PUT    Update resource configuration.
    +             - DELETE Delete resource configuration.
    |
    +-+ migrate   - POST   Request resource migration to another node.
      + relocate  - POST   Request resource relocation to another node.


Of course, it doesn't make sense for a POST/DELETE API endpoint for
nodes, but it could still be useful to make the
GET /cluster/ha/nodes/{node} route informational, e.g., output the
current maintenance state and possibly other information about nodes
there.

So something like this:

+ ha
|
+-+ nodes         - GET    List HA nodes.
  |
  +-+ {node}      - GET    Read HA node information.

I think the GET /cluster/ha/nodes/{node}/maintenance API endpoint should
be integrated into the GET /cluster/ha/nodes/{node} instead as putting a
node in/out of maintenance mode is only an action, but the state could
be more than just the node being in maintenance mode.

On second thought, is this API endpoint even used at all in the patch
series?

Hm, I see that that part is from the CLI handler, but there `disable` is
only used for two different subcommands `enable` and `disable`, so
wouldn't it be neater to have two API endpoints for that instead? Like
for example the API endpoints for VM/container start/stop/..., e.g.

- POST enable_maintenance
- POST disable_maintenance

Either way, the CLI command should then use this API handler instead of
the CLI handler to have the logic at one place only, i.e. in
ha_manager.pm

'node-maintenance' => {
    enable => [__PACKAGE__, 'node-maintenance-set', ['node'], { disable => 0 }],
    disable => [__PACKAGE__, 'node-maintenance-set', ['node'], { disable => 1 }],
},

should then be changed to:

'node-maintenance' => {
    enable => ['PVE::API2::HA::Nodes', 'enable_maintenance', ['node']],
    disable => ['PVE::API2::HA::Nodes', 'disable_maintenance', ['node']],
},

nit: for consistency's sake with the HA API endpoints, this could e.g.
be "List HA nodes.".. even though they don't really belong to the HA..

$can_audit is never used here and the check has $noerr set, so it
doesn't do anything..

The more I think about it, I'm somewhat inclined to register the whole
subclass under /nodes/{node}/ha/... instead of /cluster/ha/nodes/... to
not duplicate the information of a nodelist, which is provided by
pve-cluster and there would be something wrong with the HA Manager
anyway if those are out-of-sync and all the HA-related information can
then live in a node-specific "ha" subdirectory.

Then this API handler wouldn't be needed anymore at all.

Yes, I did use that file as the source for this package. It could very
well be one package, especially if it was placed elsewhere in the API.
I was trying to mirror the behavior of the existing nodes dir in the
API.

The API isn't specifically used here, but we have found it useful in
our local branch to have it so that we can query the transition of the
state of a host directly. I figured someone else might find it useful
as well, so I left it in here. If it should be removed, I can remove
it in the v2 series.

For this, I was mirroring the existing underlying API calls as listed
below, but I agree that enable/disable would be more clear. I'll put
that in the v2 series.

Will update this in the v2 series.

If this is how Proxmox would like it, that makes it much easier IMO. I
wasn't sure which one to include it under, so I put it under the
cluster path since a cluster must be created to even have the HA
featureset. I'm good with either, I just need to know so that I know
what to update for a v2 series.

We might be already all on the same page, so just to be sure and a
bit more context to avoid making this to HA specific:

Reporting the current (maintenance) status should go into either (or
both of) the /cluster/ha/status and/or the /cluster/resources API
endpoint.

As there are some light-weight plans to provide maintenance mode
for non-ha services, I'd indeed place that outside of a ha specific
path now already, might be even fine to use a dedicated
/nodes/{node}/maintenance API endpoint. For now the description should
state that it's only affecting HA, the non-HA parts are probably not
very complicated work, but got quite a few edge cases and design
decisions that are better done in a separate series building on top
of such API infrastructure you add here.

I see, the only thing I'm still worried about is that in the current
state the API endpoint might expose more internal structure than
necessary and should at least be documented in the API schema and/or
abstracted away.

@Thomas do you have an opinion on this?

Hm, I've only looked at the PVE API now, but one similar feature is the
PBS's maintenance mode for datastores [0], which are set by a single,
enum property 'maintenance-mode' in a PUT request.

Maybe we could add the same PUT method to @Thomas' proposed
/nodes/{node}/maintenance API endpoint, because AFAICT for non-HA use
cases we'd need some way to enable and disable maintenance mode there
too. That's also cleaner than introducing two very similar endpoints
with quite long, weirdly-cased names.

I'd leave it out for now, that transition could be conveyed in the HA
status in any case and also for the node entries in /cluster/resources,
it could be argued that doing the latter only makes really sense once
the maintenance mode is really generic, but not _that_ hard feelings
here; in any case, with the status there we can cheaply show a
maintenance icon in the web UI's resource tree.

If the API for maintenance mode is under the /nodes/{node}/maintenance
as @Thomas proposed, does it still make sense to put the code for the
API into the ha-manager package instead of the manager package? I like
the idea of the enum under this endpoint e.g. something like PUT
/nodes/{node}/maintenance --maintenance-mode enable|disable. To be
more specific to HA, could use something like --lrm-maintenance
enable|disable that way the maintenance-mode enum could stay free if
it was wanted for the more generic maintenance mode and it would
convey to the user that it was specific to HA only.

If it is under /nodes/{node}/maintenance, then yes, I also think it
should go in the pve-manager package.

IMO for the maintenance-mode parameter it's fine to make it generic
already but stating in the description that it's only affecting the HA
for now, as introducing `lrm-maintenance` might cause confusion later on
when users want to put the whole node under maintenance.. Except if
there are use cases to only 'partially' put the node in maintenance
through the API.

Then it should be rather straight-forward to implement the functionality
with issuing the CRM commands to the HA Manager with

    run_command(['ha-manager', 'crm-command', 'node-maintenance', $maintenance_mode]);

where $maintenance_mode is either 'enable' or 'disable'.

The tidy command as written does not currently include untracked
files, so that's why my newly added file did not get caught by the
formatter. Looking at git ls-files docs, adding the -co (tracked and
untracked) and the --exclude-standard (use standard exclusions)
parameters would handle targeting untracked files as well.

Re: [pve-devel] [PATCH manager 2/2] add UI for node maintenance enable/disable

[Daniel Kral]

Hm, the buttons might be a little ambiguous that these are only for LRM
entries... But I think it's a good start as there isn't a dedicated list
for the LRMs which gives more room for action buttons that can be done
on all items. But let's wait for other feedback.

var mustn't be used for new code anymore [0], and new variable names
should be in camelCase [1].

[0] https://pve.proxmox.com/wiki/Javascript_Style_Guide#Variables
[1] https://pve.proxmox.com/wiki/Javascript_Style_Guide#Casing

this could be an arrow function and the function's variable name is
rather fragile as 'disable' can be set and then does a rather different
action to the node maintenance.. Maybe just "setNodeMaintenance"?

nit: use an arrow function instead

I wasn't sure where the best place for buttons to go would be, but
Thomas Lamprecht suggested in [1] to place in the HA overview, so
that's where I figured it would fit best. I agree with his logic on
needing to check HA status before enabling/disabling the maintenance.
Selectable grid was an easy implementation there and the status was
already being polled.
