Hello, I recently upgraded to Scale. I’ve noticed that my Boot drive gets a lot more activity than I expect, especially compared to what I recall it getting when on CORE. Is this normal in Scale? Should I be concerned or just let it do its thing? My boot pool isn’t mirrored. The system dataset is …

I figured it out. For some reason, my system was swapping, even though I have ~240gb of ram. I ran swapoff -a and then disk usage slowed way down. Bonus- it seems faster too. Not sure why it was using swap. You can tell in the graph below exactly when I turned off swap. [image] edit: adding ano…

Is you log being spammed with something aggressively?

Hi @winnielinnie , Any suggestions on which log I should check? /var/log/syslog is pretty quiet. Noticed that /var/log/netdata/error.log is getting hit with this every second: [image] However, that doesn’t look like enough to generate the writes I’m seeing in the graph. Here’s log files with wri…

Just by gauging the users from the old forum (and continuing in here), SCALE seems to be more “chatty” than Core. I love Core. :smiling_face_with_tear:

I guess it just must be normal! I was used to Core barely writing at all… so it just alarmed me at first. I guess I’ll just let it do its thing. :slight_smile: Looks like the 870 EVO has a lifespan of about 300 TBW… so I guess it should be good for a while still. at least it’s not a USB thumb drive…

If it helps, here is my Scale boot drive reporting data: [20240501_14h56m12s_grim] I am on Cobia though, too early to migrate to Dragonfish for my tastes. All the logs go to the boot drive since Cobia. didn’t use to.

Dragonfish writes logs and audit entries to the boot device.

Your chart with it off looks basically like my Cobia one, which I consider “normal”. I wish you had posted the memory reporting.

Also see this thread. I’ve posted a fair amount here after discovering that swap was being “chatty” on my boot disk.
