Wrong folder size in folder overview

[tflidd]

Steps to reproduce

1. Use owncloud, sync larger folder with client on several computers
2. use it some time

Expected behaviour

OC interface shows correct folder size

Actual behaviour

In the folder view, the folder size is obviously wrong;

But when I'm opening the folder, the size is different:

du in the file system gives a size of 12 GB!
sudo ... occ files:scan username doesn't help.

There is also a recent report on the forum: https://forum.owncloud.org/viewtopic.php?f=31&t=28525&p=88359

Somehow related to #14298 but encryption has been disabled since then (the total storage on the user's personal page is 13.5 GB and in the filesystem it is 14 GB).

Server configuration

Operating system: Ubuntu 14.04

Web server: Apache

Database: MySQL

Updated from an older ownCloud or fresh install: updated many times

Are you using external storage, if yes which one: not this user

Are you using encryption: no

Are you using an external user-backend, if yes which one: no

Logfiles: There is nothing specific in the logfiles, I can't say when it exactly appeared. Perhaps some interrupted sync or lost wifi connection??

@icewind1991 Can you have a look?

[tflidd]

I tried the fix for shared folders in #14861 but it didn't work (there are no shared folders)

@tflidd can you check the "size" values in oc_filecache of the folders ?

Maybe there were multiple scanners trying to compute the folder sizes at the same time concurrently and gave wrong results.

[tflidd]

The parent folder (shown in images above) has a size of: 12037693124 in the filecache-table. There is still the field with unencrypted size (encryption was turned off some months ago): 449034503 (this seems to be the size shown on the interface).
edit: the "encrypted" field is 0 for all files.

[PVince81]

Hmm, if I remember correctly, whenever you disable encryption, it will not automatically recompute the sizes, so you might still have old sizes there.

Did you try running ./occ files:scan --all ?

[tflidd]

I did run the ./occ files:scan several times but it didn't change anything.
In the meantime, I repaired my filecache-table with this sql-command:

UPDATE `oc_filecache` SET `unencrypted_size`=0 WHERE `encrypted`=0

[PVince81]

Ah yes, that would work too.

[tflidd]

I leave it open for you, if you want to fix the encryption enabling/disabling-routine. From my point of view, the problem is solved.

[PVince81]

Thanks. I think I discussed this with @schiesbn before and decide to leave it.
Also, since 8.1 disabling encryption will be done using a separate mechanism.

@schiesbn your call

[PVince81]

Closing as obsolete.

Since encryption 2.0 (OC >= 8.1) the size column will always contain the unencrypted size, so doesn't need to be updated after encrypting/decrypting.
