Server has no maintenance window start time configured

jtr · January 31, 2024, 7:26pm

It’s a newer check, but all is does it make sure that parameter has a value and I don’t see any obvious bugs in the code.

Are you sure things are quoted correctly? Can you provide the parsed by running occ config:list system?

huhas12 · January 31, 2024, 7:36pm

Sure!

ou may use your browser or the occ upgrade command to do the upgrade

Tengo el mismo inconveniente todo andaba de maravilla sin alertas o errores hasta esta nueva actualización no se que deba modificar para resolverlo me gusta ver todo perfecto

jtr · February 1, 2024, 2:53pm

"version": "25.0.8.2",

That can’t be your active configuration. It’s for NC25!

joe2014 · February 1, 2024, 3:37pm

hi guys ,did u resolve this problem?
i get same one ,when i update to 28.0.2

bb77 · February 1, 2024, 3:46pm

There’s a link in the warning message to the documentation

You have to add the following line line to your config.php:

'maintenance_window_start' => 1,

1 stands for the hour when you want the maintainenance window to start in UTC time, so in the above example the maintainenance window starts at 01:00 UTC Time.

Nextcloud Documentation:
https://docs.nextcloud.com/server/28/go.php?to=admin-background-jobs

What is UTC time?:
https://www.utctime.net/

UTC time zone converter:

jhon2323 · February 1, 2024, 4:06pm

Amigo exactamente en que lugar de la configuracion php debe ir
‘maintenance_window_start’ => 1,

bb77 · February 1, 2024, 4:35pm

Anywhere except in an array. If you want to be on the safe side, place it in the second last line above the );

Or you could use the occ config command.

Example:

sudo -u www-data php /path/to/nextcloud/occ config:system:set maintenance_window_start --value="1" --type=integer`

jhon2323 · February 1, 2024, 4:51pm

mil gracias esa era la solución vuelvo a tener todo en orden

ngreene · February 1, 2024, 5:15pm

Worked for me
‘maintenance_window_start’ => 1, in the Config.php file
be sure to restart apache2 and PHP (as applies) and then reboot.
Notice gone

huhas12 · February 1, 2024, 5:28pm

What you mean it’s 25.0.8.2? I am updating again to check!

joe2014 · February 2, 2024, 12:59am

it is really work now, thank you very much.

huhas12 · February 2, 2024, 7:36pm

Still the same. I updated to 28.0.2, restarted apache and php service, waited for a day.

jtr · February 2, 2024, 9:15pm

@huhas12 The configuration you posted yesterday was for NC25. Are you sure you’re modifying your live configuration? Or perhaps do you have a second Nextcloud Server installation active?

politas · February 2, 2024, 9:36pm

It would have been nice to add this parameter to the configuration page before adding the warning about it, especially since it needs to be in UTC, making it really easy to set an inappropriate time. Can we get a selector in the configuration when CRON method is selected that allows setting this parameter using a local time selector?

bb77 · February 3, 2024, 12:44pm

I wrote a small bash script that sets the parameter based on the local time of your server. Maybe it is of any help:

#!/bin/bash
#
# Set the local time when you want the maintenance window to start:
# (Only use full hours in 24hrs (HH:MM) formating) e.g. "00:00" "01:00" "02:00" etc...)
#
TIME="01:00"
#
# Set the path where your Nextcloud is installed:
#
NCPATH="/var/www/nextcloud"
#
# Set the web server user:
#
WWWUSER="www-data"
#
# DO NOT CHANGE ANYTHING BELOW THIS LINE!
#
LOCALSTARTTIME=$(date -d "$TIME" +%s)
UTCSTARTTIME=$(date -u -d "@$LOCALSTARTTIME" "+%-H")
sudo -u $WWWUSER php $NCPATH/occ config:system:set maintenance_window_start --value="$UTCSTARTTIME" --type=integer
exit 0

This may be of interest to those of you who, like me, don’t want to set a time window at all. So all tasks should be able to be started at any time.
In order for the message to disappear anyway, you have to deactivate the time window with the value 100:

  'maintenance_window_start' => 100,

Good to know, and thanks for sharing.

Is this documented somewhere, or how did you find out?

ernolf · February 3, 2024, 2:38pm

Documented here:

github.com

nextcloud/server/blob/63f327c7ba35e189d2f9e05a16a3fd6526afe678/config/config.sample.php#L1412

           *
           * Some background jobs only run once a day. When an hour is defined for this config,
           * the background jobs which advertise themselves as not time sensitive will be
           * delayed during the "working" hours and only run in the 4 hours after the given time.
           * This is e.g. used for activity expiration, suspicious login training and update checks.
           *
           * A value of 1 e.g. will only run these background jobs between 01:00am UTC and 05:00am UTC.
           *
           * Defaults to ``100`` which disables the feature

… and since it only checks IF it is set to any value at all to supress the warning:

github.com

nextcloud/server/blob/master/apps/settings/lib/SetupChecks/MaintenanceWindowStart.php#L52


      
          
          	public function getCategory(): string {

          	public function getName(): string {
          		return $this->l10n->t('Maintenance window start');
          	}
          
          	public function run(): SetupResult {
          		$configValue = $this->config->getSystemValue('maintenance_window_start', null);
          		if ($configValue === null) {
          			return SetupResult::warning(
          				$this->l10n->t('Server has no maintenance window start time configured. This means resource intensive daily background jobs will also be executed during your main usage time.

          			);
          		}
          
          		$startValue = (int) $configValue;
          		$endValue = ($startValue + 6) % 24;
          		return SetupResult::success(

Find out here, that you can deactivate the time window with any value greater than 23:

          		// set to run indefinitely if needed
          		if (strpos(@ini_get('disable_functions'), 'set_time_limit') === false) {

Ah yes, the config.sample.php file, I should have thought of that myself

Thanks

EDIT: In the meantime it’s also in the docs: Configuration Parameters — Nextcloud latest Administration Manual latest documentation

Or maybe it has been since the feature was introduced, and I didn’t find it? Never mind. It’s in there now.
