Bug description

Hello guys, I have more than a week dealing with a serious problem with my nextcloud installation, I tried to test many things before writing here
I have a nextcloud installation for months that I use to share content with family, friends and clients, I have been using cloudflare's R2 as primary S3 storage, everything worked great for months, until a week ago the installation is completely broken and no shows the files, if it tries to open a previously shared url if it shows the list of files but when trying to play or load them an error is shown, I already did a new installation, but when configuring S3 as primary storage it returns and breaks, it does not load the css styles of the installation, I will leave some screenshots of how it is shown

Steps to reproduce

1. create a new installation of nextcloud version 24.0.5
2. configure s3 as primary storage
3. the installation is completely broken

Expected behavior

that everything works correctly as this great software does

Additional info

Hi,

Do you see the file-listings in your instance? (via web-interface)
Is the data there in your S3 storage? (all 'numbered files')
Do you see the previews? (via web-interface)

take a good hard look at your sql-table oc_storages. When you are working completely in S3 all entries should be 'object:...' I think you may have some history with 'local:' folders.. DO NOT simply remove those entries!!

Could you post the oc_storages info? (do anonymize the data)

I have quite a bit of experience with NextCloud->S3, so I might just be able to help you out..

hi
I really appreciate your help, here I show you my oc_storage table

[mrAceT]

please answer:

1. Do you see the file-listings in your instance? (via web-interface)
2. Is the data there in your S3 storage? (all 'numbered files')
3. Do you see the previews? (via web-interface)

[edwinosky]

the web interface does not show the files, not previews, it does not even try to upload them, in cloudflare R2 I have more than 1TB of data but I cannot access it without nextcloud

[mrAceT]

you have
28: object::user::sonya => GOOD
49: home::sonya => local storage! => NOT good

you have
1: local::/var.... => NOT good!
29: object::store.. => GOOD!

check your oc_filecache and take a good look at at the storage ID's

I have had trouble with migrating to S3 storage.. and have written a migration tool to local (take a look at: lukasmu/nextcloud-s3-to-disk-migration#6) and later have built the reverse back to s3..

what you will need to do is first make backups! Of your data.. of your SQL.

Did you have a separate storage config? (that was part of my trouble..)

Is there data in your LOCAL data folder? (besides the default stuff)

check your oc_filecache, are there storage id's attached to number 1? and 49?

This BRUTE FORCE approach might work (but do make backups..........):

• go to maintenance mode (beyond important)
• check your config => is all set to S3?
• remove the local storages in oc_storages (local.. home..)
• remove all the local storage references in your oc_filecache
• go out of maintenance mode

This Q & D approach might work.. (but do make backups..........)

The problem is you are now "in limbo" things are set to local AND S3.. Nextcloud seems to prefer local.. resulting in you not seeing S3..

[edwinosky]

If I already have a backup of my database, I use plesk so it is very easy, and I also have the R2 bucket backed up in another bucket
I will try to carry out the steps that you indicate in oc_storage and in oc_filecache as soon as I finish I come back here to talk to you about the results

[edwinosky]

hi @mrAceT
I already deleted the oc_storage entries, the error is still not fixed, now I ask you in oc_filecache I have more than half a million entries, will I be able to delete them all?

[mrAceT]

oc_filecache I have more than half a million entries, will I be able to delete them all?

NO!!

In contrary to local storage, S3 storage can NOT rebuild itself via the data in S3 (that should be possible, but for some reason NextCloud has decided to use the cryptic numbers, I have asked about this in the forum, but to my knowledge no one has ever given a good answer)

check your oc_filecache, are there storage id's attached to number 1? and 49?
remove all the local storage references in your oc_filecache

With that last sentence I ment the numbers of all those 'home & local' ID's.. if you would remove those, all data in there should refer to S3-data.. So for Sonya.. how many entries are there in oc_filecache with storage ID 28 ? Does that "feel right"?

delete the oc_filecache entries with ID 1 ID 28 and ID 49, it does not solve the problem either, I remember that it happened to me about three months ago and I managed to solve it with a command that I execute in the occ binary, that command was written by someone in the official forum but I couldn't find it
I have been thinking about using the script that you recommended above but I think I will need enough storage space, that implies changing vps

i'm pretty sure my problem lies with the database because i install a clean instance with s3 and it works fine, it just breaks when i import the database

Oh dear.. number 28 are the entries for OBJECT->S3.. do you understand the structure of the numbers? You need to remove the NOT object-numbers

The truth is that all the data that matters to me is in the admin account, and since I share it with other users, I can delete the other user accounts without problems.

Is there any way to do a kind of cleanup to the database without touching the admin data?

Then I'dd keep it simple.. and remove all the other accounts via the web-interface.. then you would have a nice clean oc_storage (the basis S3 entry and that one user?. Then remove all but those two numbers form the oc_filecache .. If nothing else has been broken, you should see all your files you'dd want to rescue in your filecache..

Also, if the other users are "simply shares".. then you'dd not have any other files lingering in your S3 storage..
