The issue you are facing:

I am seeing constant error message “low water mark reached dropping 100% metrics”. Can someone explain what this is?

I have one of my drives in pool degraded but other than there is nothing else happened. In the past, it degraded also while I change the drive but did not exhibit this issue so I can not to degrade problem. I can not login to system while in the state wondering what this is error is all about?

Is this the first time you’ve seen this error? (Y/N):

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:
