Hello everyone!

I'll be taking the site down for two maintenance windows this week to complete our server migration.

  • Weds Jan 29th - 09:00 - 11:00 PT (12:00 - 14:00 ET)
  • Thurs Jan 30th - 09:00 - 11:00 PT (12:00 - 14:00 ET)

During the first window I'll be migrating us from OVH to our new dedicated hardware. After this migration there will likely be some temporarily broken images, as it takes approximately 8 hours to resync our object storage from OVH.

This is a major change and despite my testing, may have some unintended side effects. If you run into any problems that aren't just a broken image, please let us know.

The second maintenance window is to migrate our pict-rs database from it's local sled-db into our primary postgres DB. This is a much smaller change but since pict-rs checks every image as it goes through them, it takes about 1.5 hours.

As usual, you can check https://status.lemmy.ca/ for updates.

First move complete, went smoothly =)

The broken images and thumbnails should fill in over the next 8-10 hours 🀞

Let me know how performance is for everyone, I expect it to be quite a bit snappier!

[–] [email protected] 5 points 4 weeks ago* (last edited 4 weeks ago)

Much faster than I expected!

Performance already seems fine for me

Edit: I can scroll as fast as I can on my phone and never have to wait for a post to load, your upgraded server is awesome!

[–] [email protected] 4 points 4 weeks ago

That was really quick!

[–] [email protected] 3 points 3 weeks ago

Beautiful work ... thanks for everything

[–] [email protected] 2 points 4 weeks ago* (last edited 4 weeks ago)

Didn't even notice. Today's been busier at work. :D

Sorted by most comments, opened a 400-comment thread. Fast-fast.

[–] [email protected] 1 points 3 weeks ago

Seems a lot snappier for sure!

[–] [email protected] 24 points 1 month ago

Good luck with the server migration!

Second move complete, all done for now!

[–] [email protected] 3 points 3 weeks ago

Great news. I hope it was relatively non-eventful.

[–] [email protected] 1 points 3 weeks ago

Beautiful work ... everything purring like a well tuned motor over here

Thanks!

I've noticed my profile pic is partially broken.

The mini-thumbnail beside my name in comments appears fine; but the image in 'about' on my profile is broken. (viewed from Jerboa).

It opens properly in full-res when you click on the broken image though.

Haven't tried re-uploading it yet. Just figured I'd report it.

/edit Broken in the side bar too

Fixed with a re-upload.

[–] [email protected] 1 points 3 weeks ago (2 children)

Do you happen to have the broken image url still?

[–] [email protected] 1 points 3 weeks ago* (last edited 3 weeks ago)

I don't, but I'll pm you an IP address. Check the logs for 404s from that ip? (around 4 hours ago)

[–] [email protected] 1 points 3 weeks ago (2 children)

It looks like your profile is doing the same; but only when viewed from Jerboa.

I didn't check mine in a browser at the time.

[–] [email protected] 2 points 3 weeks ago

Thanks, I see it too. Digging.

[–] [email protected] 2 points 3 weeks ago (1 children)

I think this is fixed now. I'm not sure why but pictrs was expecting a bunch of resized images that don't exist in either the old or new object stores. I've manually cleaned up the DB.

[–] [email protected] 2 points 3 weeks ago* (last edited 3 weeks ago) (2 children)

Many of them are, but scrolling through this thread and checking the profiles of various lemmy.ca accounts; some are still broken.

@[email protected] for example

[–] [email protected] 1 points 3 weeks ago (1 children)

I've hacked in a dirty dirty fix for now. It looks like the pictrs database migration failed horribly and cloudflare was caching the images, so nobody noticed. Now I've got two copies of pictrs running (old + new) and some code in place to try both of them.

Sigh.

[–] [email protected] 1 points 3 weeks ago

Oh shit.... Well at least you found it before everything just stopped working? :(

Thanks for your efforts m8; I appreciate the hard work. Best of luck fixing that.

[–] [email protected] 1 points 3 weeks ago

Well shit, cloudflare's been caching all our images and deceiving me into thinking stuff was working properly. Digging, but I made a mess =(

[–] [email protected] 8 points 4 weeks ago

Damn, not even 20min?

Well done. πŸ‘

[–] [email protected] 8 points 1 month ago

Thank you for the updatesπŸ€—
I hope the migration goes well!βœŠπŸ€

[–] Shadow 4 points 4 weeks ago

Incoming federation test.

[–] [email protected] 2 points 4 weeks ago

I see the Canuck lemming

[–] [email protected] 7 points 4 weeks ago* (last edited 4 weeks ago) (1 children)

What's the best way to let you know if we're having issues after the maintenance windows? Any on a different platform if we have issues accessing Lemmy?

Thanks for all the hard work!!

[–] [email protected] 10 points 4 weeks ago

We're also in the lemmy rooms on matrix, but [email protected] is probably the quickest method to get my attention if you can't even post on Lemmy at all. I really don't expect any issues though.

[–] [email protected] 7 points 4 weeks ago

Exciting. This brings us one step closer to Pixelfed and Friendica hosted by Fedecan.

[–] [email protected] 6 points 4 weeks ago

Thank you for the great work Shadow!

I’m so excited for the increased autonomy of Lemmy.ca 🫑
