Tips for "Care and Feeding" of my Instance - Disk Usage Rising (lemmy.ml)

submitted 1 year ago by [email protected] to c/[email protected]

4 comments fedilink hide all child comments

Any helpful tips for general care and feeding I should be doing on a regular basis?

I know I need to keep an eye on updates and re-run my ansible setup form time to time to stay up to date.

But I have also been keeping an eye on my VPS metrics to see when/if I need to beef up the server.

One thing I am noticing is a steadily increasing disk utilization (which mostly makes sense except its seeming a bit faster than I expected as most all media is links to external sites rather than uploading media directly to my instance).

Anything I can do to manage that short of just adding more space? Like are there logs/cached content that need to be purged from time to time?

Thank you!

The main cause for the steady rise in disk usage that I'm seeing is the activities table, which contains the full JSON of all ActivityPub messages seen by the instance. It appears Lemmy automatically removes entries older than 6 months though.

Gotcha thanks! Thats good to know. Based on the originating ticket: https://github.com/LemmyNet/lemmy/issues/1133

Sounds like it might be safe for me to purge that table a bit more often as well.

Dumb question, how are you profiling (RE your mention of getting a better idea of which tables might be bloated) your DB? Just SSHing into your box and direct connecting to DB? Or are there other recommended workflows?
