[Almost done... Update] Expected instance downtime for upgrading pict-rs (mander.xyz)

EDIT:

The pictrs migration is still taking place in the background, and there might be some problems displaying new or some old images, as well as a bit slower site performance. But it seems like the site can run well now.

The lemmy backend makes use of pict-rs for hosting images. A new version (0.5.0) was recently released, and upgrading from the previous version involves a migration that is expected to take a few hours.

I am planning to run that migration either tomorrow evening or on Saturday. If all goes well, the instance will be down for only a few hours.

Just a heads up in case you stop by and see that the site is unavailable.

Horrors upon horrors.

😅 I have read and re-read the migration guide. Seems simple enough.... And the current backup is almost ready!

Whenever I say that when trying to do a docker container, I feel like Sideshow Bob making friends with rakes.

Does this have anything to do with the issues earlier today (maybe 9-10 hours ago)? After several failed attempts to open new messages or reload the page, I got a message stating that the server was rebooting, and a couple minutes later everything was working fine again.

That's probably when I ran a quick upgrade from 0.19.2-rc-5 to 0.1.9.2! If I know it will take only ~5 mins I usually just go ahead without notice.

... and just hope nobody else notices? 😆 I figured something was going on and it would be back shortly, but I also know sometimes servers do thing that admins weren't aware of, figured I would just check in.

Yeah, since it is such a short downtime - comparable to what one might randomly see anyway when the CPU spikes for a mysterious reason, I figure that it is not so helpful to plan ahead and make an announcement. I just do it when I have some time.

...I kind of chose the worst time ever to migrate to this instance, didn't I? [laughs]

I hope that the upgrade goes well!

[–] Sal@mander.xyz 2 points 8 months ago (1 children)

....Sorry 😅

And welcome!

[–] lvxferre@mander.xyz 3 points 8 months ago (1 children)

Thanks for the welcome!

On other matter: I'm planning to create a Linguistics community here, would it be OK? I noticed a few comms about other human sciences, but asking it to be sure.

[–] Sal@mander.xyz 2 points 8 months ago

Sure! Thank you for creating a community!
