Missing guide pages on haiku-os.org

[pulkomandy]

The following pages disappeared from the website:

• ​https://www.haiku-os.org/guides
• ​https://www.haiku-os.org/guides/building/pre-reqs

Can they be restored?

[arfonzo]

It may be more than just these two pages, perhaps everything under the guides section.

we're worried about compromise or disk corruption at this point. I saw lots of spammers creating accounts this morning, and we noticed some disk / malloc errors in dmesg:

[286510.697200] systemd-journald[271]: Failed to write entry (20 items, 701 bytes), ignoring: Cannot allocate memory
[289388.892195] ata1.00: failed command: WRITE DMA

Nielx is looking at it in a few mins.

I rebuilt the guide index page by recreating it from archive.org, but the paths still existed pointing to the old node id.

I fixed that, but all the book pages also still point to the old node ID:

Old: ​http://www.haiku-os.org/node/3226 (missing?!)

Recreated: ​https://www.haiku-os.org/node/6067

Update: the reason why the pages have disappeared has been found. The user id had been set to the value 0, which is not a valid user.

The cause is not known.

Currently we are trying to restore the correct user ids from a backup.

Replying to nielx:

Currently we are trying to restore the correct user ids from a backup.

Technically, UID 0 is used for the anonymous user role, and appears as the first entry in the users table. I suspect you know that already though, and were just trying to keep the explanation simple. :) It's weird that valid uids for authenticated users were replaced by the anonymous user id somehow. Hopefully you find out the root cause soon enough after the problem is corrected.

[nielx]

Actually that is very useful information. Are you sure it exists in the user table? Because currently it doesn't (which explains why suddenly the pages would stop working).

[nielx]

Note to self: see ​https://drupal.org/node/1029506 on how to restore the user.

Thanks jprostko, that probably fixes the issue for good.

Still no explanation on the cause (how got the anonymous user deleted?) but at least for the future we will not run into unexpected problems.

[jprostko]

Hey, sorry I'm slow on the response here. I was going to suggest that maybe the anonymous role accidentally got deleted, but your mention of restoring the uids from the backup made me think they were actually associated with uids greater than 0.

In any case, I am glad to know you got it fixed!
