Elasticsearch : Snapshots not executed automatically (cron schedule issue)

[Ksnov]

Hi !

I've changed the schedule of my managed snapshot policy. By default, the cron is each 30 minutes, and I wanted just one per day. Since... the snapshots are not executed automatically...

I've putted back the previous configuration but it doesn't fixed the problem

There's no recent failure (last failure is Feb 03, 2022 10:30 AM).
BUT ! I'm able to manually take a snapshot. It's only the cron that is not working.

My deployment is at version 7.17.1, this is the json config returned by GET https://ES.HOST/_slm/policy/ :

{
    "cloud-snapshot-policy": {
        "version": 10,
        "modified_date_millis": 1648205967792,
        "policy": {
            "name": "<cloud-snapshot-{now/d}>",
            "schedule": "0 */30 * * * ?",
            "repository": "found-snapshots",
            "config": {
                "partial": true
            },
            "retention": {
                "expire_after": "259200s",
                "min_count": 10,
                "max_count": 100
            }
        },
        "last_success": {
            "snapshot_name": "cloud-snapshot-2022.03.28-7bsk_rtkt7klcmre3yghtq",
            "start_time": 1648449376402,
            "time": 1648451047195
        },
        "last_failure": {
            "snapshot_name": "cloud-snapshot-2022.02.03-yyl4pcwfqvynla9v7noqgg",
            "time": 1643880630250
        },
        "next_execution_millis": 1648458000000,
        "stats": {
            "policy": "cloud-snapshot-policy",
            "snapshots_taken": 23346,
            "snapshots_failed": 230,
            "snapshots_deleted": 23214,
            "snapshot_deletion_failures": 119
        }
    }
}

My deployment is managed on Elastic Cloud, using Azure.

I've taken a snapshot manually 2 hours ago and, as you can see, a snapshot should have been executed 3 minutes ago but doesn't appear in my found-snapshots reposity (even in the logs, there's nothing...)

So it's "just" the cron schedule that needs to be fixed... Any suggestion ?

Thanks !
