discussion Legacy Attachment System Corruption – Partial Recovery and Archive Release

[Haywoodspartan]

After a lengthy investigation and multiple recovery attempts, we have concluded that a significant portion of the forum’s legacy attachment system has been severely damaged and is no longer recoverable within XenForo.

What happened​

The original server experienced a critical boot partition failure, which prevented the system from starting normally. In order to bring the forum back online, other administrators performed a manual salvage of the filesystem from the affected disk.

While a large amount of data was successfully recovered, the recovery process did not capture the entire attachment structure intact. Some directories were copied incompletely, some files were recovered without their original metadata, and certain portions of the attachment storage hierarchy were likely missed during the salvage process.

As a result, the recovered data is no longer consistent with XenForo’s attachment indexing system.

Why attachments appear broken​

XenForo attachments rely on a strict relationship between database records and files stored on disk.

Each attachment requires:

1. A database record in xf_attachment
2. A corresponding entry in <span>xf_attachment_data
3. A matching data_id
4. A matching file hash
5. A file located in the correct bucket directory

If any part of this chain is broken, XenForo cannot serve the attachment.

During analysis we discovered several problems with the salvaged data:

• Attachment files exist but their hashes no longer match database records
• Some files were recovered with modified or incomplete filenames
• Certain attachment bucket directories appear partially missing
• Some attachments contain both .data files and sidecar image files .jpg, .png, .webp, but the database references no longer align
• Some database entries exist without a corresponding file on disk

What we will do next​

Since the salvaged attachment data is incomplete but still contains many historical images, we will be taking the following steps:

• The original legacy forum (LC) will be archived
• The salvaged attachment image data will be packaged and released as a downloadable ZIP archive
• This archive will contain the recovered image files exactly as they were salvaged, without modification

This will allow members of the community to:

• download the recovered images
• preserve historical content
• potentially recover individual images manually if needed

Moving forward​

The goal now is to stabilize the forum going forward while preserving as much historical material as possible.

More information about the archive and download availability will be posted once the packaging process is complete.

We appreciate everyone’s patience while we work through the aftermath of the server failure and incomplete filesystem recovery.


I would like you all to give me your serious no BS input and I would greatly appreciate the feedback.

The New Server is now Built from the ground up with Redundancies and Safeguards in Place but the forum in it's current state is looking like a lost cause.

I will do my best with what we have if you all choose to keep the old one or if you all want to move to a completely clean system.

summarized portion.

A major portion of the forum’s old attachment system was damaged during the server failure and recovery process. While much of the site data was salvaged, the recovered attachment files no longer properly match XenForo’s database structure, which is why many older attachments appear broken or missing.


Because XenForo requires exact links between database records, file hashes, and storage paths, a large part of the legacy attachment system cannot be fully restored inside the forum itself.


At this point, the old forum is being treated as a legacy archive. The recovered historical image data will likely be packaged into a downloadable ZIP so members can preserve and manually access what was saved.


The new server has already been rebuilt with stronger safeguards and redundancy in place. The remaining decision is whether to keep trying to maintain the damaged old forum, or move forward with a completely clean system while preserving what we still can from the original.

Thanks for the update on the broken images, videos, and so on.

I figured it had to do with the server crash once again, and it wasn't the first time either.

but it is the worse of the worse crash, basically we are archiving the site and building a new forum under the same name.

 

[Republican Bear]

he is changing the text font lol.

Mine was just as bad until I lowered the glow and chose different colors.

 

[Haywoodspartan]

Yeah I jumped into cesspool hoping it would have been a good recovery.
But as Little Mac has shown time and time again he has no recovery.

Seems like it's been a bad year all together though since the update and mass forum registrations from ATF.

Anyway keep up the good work and I hope the site gets back to normal at a certain point.

It's not the best news, but it's certainly good news.

Thanks for the work,

what would you like feedback on though?
on this plan?

Aren't most people here for the new content?
I would maybe try to salvage the last weeks or so and just consider the rest a fresh start.

 

[Bzshr]

Sad to hear what happened to the forum, but I believe that's a good lesson learned. Let the good members in the forum try to salvage what they can, and you guys focus on getting the new forum up and running for everyone else. Hope these new safeguards protect the new forum moving forward!

 

[Decom]

I’d say whatever’s safer , which sounds like the new server and salvaging why you can. I’m sure eventually all those old files and images and etc will EVENTUALLY find its way back here one way or another

 

[Dip!]

Ok so i can be kinda slow at understanding things.


So, are we completely starting over? Or will their be some things transferred over? The zip file will basically be a "screenshot" of this website? Like can i use that file to know what images i had where in my thread?

Sorry if this was already explaind. Please tell me in simple words like im stupid.

 

[Nicest_Incest]

I imagine the hardest hit sections are probably the images and clips in the AI P4-5 area. Just about every post on every thread there was uploaded as attachments irrc. Sure, losing an incest patch or whatever that was never put in the OP sucks but losing blonde and ginger lolis doing lewd things to their daddy while he's asleep sucks harder.

 

[Ttian]

At the very least we didnt lose everything. A thanks to the devs for all their hard work.

Meh, I don't really care about whatever hidden section y'all are using that will certainly not lead someone to jail one day, I just want a functioning website to access games not permitted by the other website that I won't name because whoever coded this website felt too immature not to hijack whenever it's typed. Oh and I'd like maybe for one fucking day not always having to be force fed whatever drama the admin has that NEED everyone to read. I just want the thumbnail in the latest updates page to work. That's all.

I can't speak for everybody but I'm in US where it's legal, even if I didn't bother with logless VPNs. Even visiting this site in some shithole like Australia? Yeah, there you might as well get into real human trafficking, similar risk as lewd loli art but a lot more money. As far as shit breaking I'm used to it after 4 years. In the early days before they decided to add things and change shit that didn't need added or changed (the simpler something is = the fewer things that can go wrong) the only thing to worry about was changing hosts every 2 weeks with 2-3 days of downtime since back then everything was public.

 

[Republican Bear]

Yeah the AI sections have lost most content and it probably wont be recovered as most of those members have moved on,

The P5 has been a mess for a while though since all the forum errors and other sub-site getting deleted a year ago.

 

[VSCDB]

I have some technical questions if I may.

The original server experienced a critical boot partition failure,

What was the cause? Corruption of the MBR, faulty/erroring disk, some system service that somehow wrote to boot, a faulty update?
Or was it just one of these weird things sometimes happening with some really long running servers that they just seem to wait until system shutdown/reseat to manifest the problem. Could the boot partition already have been damaged for a while? Since these files there are usually loaded into ram from the bootloader, the damage could have originated ever since the last reseat.

As a result, the recovered data is no longer consistent with XenForo’s attachment indexing system.

What actually caused this? Was it the crash?

Attachment files exist but their hashes no longer match database records

If the hash changed, that usually means the data changed. So how is it possible the attachments still exist, but the files have different bits? Was it a distributed file system? Is XFs hash reliant on the exact metadata (creation date and modification date)?

Some files were recovered with modified or incomplete filenames

Basically the same question as in the point before with addition, is this because of metadata/encoding of the file metadreplies

Since the salvaged attachment data is incomplete but still contains many historical images

Does this mean this goes only for the attachment part of the forum, or the whole forum content, like threads and replies?

Some directories were copied incompletely, some files were recovered without their original metadata, and certain portions of the attachment storage hierarchy were likely missed during the salvage process.

How did you guys actually do it in the end? Simple copy of the root dir? Since it was obviously no full file backup, and why was this data missed? Was the normal data also effected by the partition corruption?

Anyway, all in all still good job. And happy to hear some news. Just wanted to ask, since these were questions I had while reading

Time for the new guys to fill the forum with just as much goodies.

It hasn't though and mime has tried her hardest to get more members interested.

I'll miss all those A.I videos though may they rest in peace.
