The virtual disk for my lemmy instance filled up which caused lemmy to throw a lot of errors. I resized the disk and expanded the filesystem but now the pictrs container is constantly restarting.

You can still see the logs using docker logs container_name>. To get the container name you can use docker ps -a. It should list the pictrs container there. The container name is usually the last column of the output.

Seems like your pictrs database is corrupted.

[-] admin@leemyalone.org 3 points 1 year ago* (last edited 1 year ago)

Is there a way to reset the pictrs DB without affecting the posts, commenst and users DB?

[-] SpecGeo@lemmy.world 1 points 1 year ago

You can try mounting a new folder as pictrs volume. I assume your other data will be safe since it is in the database.

[-] ksynwa@lemmygrad.ml 1 points 1 year ago

pictrs database is completely separate from lemmy database. If you want you just delete everything in the pictrs volume and start afresh. You will lose all images though.

[-] admin@leemyalone.org 2 points 1 year ago

There's only two local posts on my instance so i'm not worried about losing thoseabout.

Will the pictrs from subscribed communities in other instances be restored after a db reset?

[-] ksynwa@lemmygrad.ml 0 points 1 year ago

pictrs from subscribed communities in other instances

Dont worry about those. Those images are not stored by your pictrs instance. They are directly fetched from the native instances.

[-] admin@leemyalone.org 1 points 1 year ago* (last edited 1 year ago)

OK. I just deleted the pictrs folder from srv/lemmy/leemyalone.org/volumes but I am still having the same issue.

[-] ksynwa@lemmygrad.ml 2 points 1 year ago

You'll have to check again. My guess is though you should not have deleted the pictrs folders. Just its contents. You can recreate the folder again though:

mkdir pictrs
sudo chown 991:991 pictrs

But check the logs first.

[-] admin@leemyalone.org 3 points 1 year ago* (last edited 1 year ago)

In my previous comment I should have mentioned that I did recreate the pictrs folder. Your instruction to change set the ownership of the pictures folder to 991:991 did the trick.

Thank you so much for your help here. Much appreciated.
