You didn’t give enough context, but I think this is a collectd matter rather than Nextcloud related.

what is collectd? Is this a truenas thing then? After disabling power management for HDDs i stopped seeing but started reappearing during uploading of about 1GB data comprising of ~100KB chunks.

It’s not solely a TrueNAS thing, but, yes, AFAIK TrueNAS has it. As for what it is, check your favorite search engine. :slight_smile:
