Attachment file replacement fails

[BobF]

To enhance performance, I moved the attachments to the file system. This was done successfully.
When I tried to replace an attachment using the admincp, I received an error "Failed to write file. Check disc quotas and permissions". I had assumed that the permissions were correct because the move to the file system was successful and there are no disc quotas set.

Moving the attachments back to the database allowed me to successfully replace the attachment.

What could be set wrong when attachments were in the file system?

'Disc quota' is a server issue. Did you try contacting your host?

[BobF]

It's not a drive space/quota issue, I control the server and it has many gigs of free space.

Check both the overall limit:

Admin CP -> vBulletin Options -> Message Attachment Options -> Limit Space Taken Up By Attachments (Total)

...and the specific Usergroup permissions:

Admin CP -> Usergroups -> Usergroup Manager -> Edit Usergroup -> Attachment Permissions -> Space (in bytes) that a user's total attachment usage may consume

[BobF]

Limit Space Taken Up By Attachments (Total) set to 0

There is no attachment permissions option for the Unregistered users group.

Note: The newsgroup was imported and the messages/attachments are guest messages.

Registered user group attachment permissions:
Space (in bytes) that a user's total attachment usage may consume set to 0

Are group attachment permissions ignored if attachments are in the database?

Check the permissions on the attachment directory and all subdirectories. They should be 777

[BobF]

As a test, I set directory permissions (Windows server 2003) as follows:
Everyone - Full control
Internet Guest account - Full control
Launch IIS process account - Full control
All permissions are inherited.

Still receive the error

Note: I can upload new attachments to the forum without problem, it's just replacing a file that fails (and that only when attachments are in the file system - I can replace the file when attachments are in the MySQL database)
The file size of the attachment is about 500k

The following info may or may not be useful:
Server Type WINNT
Web Server isapi
PHP 5.2.6
PHP Max Post Size 2.00 MB A
PHP Maximum Upload Size 2.00 MB
PHP Memory Limit 128.00 MB
MySQL Version 5.0.67-community-nt-log
MySQL Packet Size 1.00 MB

What does the Unregistered usergroup have to do with post #1? I'm a bit confused.

bit complicated but here's my line of thought.
I think the imported messages and attachments go into the Guest account
I think the Guest account is a member of the Unregistered usergroup
so, that is the usergroup permissions I was trying to check to answer your question in the first quote above.

Is the Guest user not a member of the Unregistered users group? If not, which user group should I check permissions for?

[Steve Machol]

That may be the problem right there. There is no way to check or enforce disc quota limits on unregistered posts. Unfortunately I don't know of any way to do this except to either remove all such attachments or keep attachments in the database.

[BobF]

Is there a way to move all Guest messages for a forum into a Registered user account temporarily and back again after attachment fixes are done?

(assuming this is actually the cause of the attachment replacement failure)
