OpenStack Swift segments are not removed when deleting a large object file (SLO)

[BIGAIRFOX]

Hello group,

My English is not so good but I'll give it a try.

I use Cyberduck with OpenStack Swift on Informaniak Swiss Backup.

When I upload a larger file it is stored in 2 directories (default and default_segments). In default is the correct name with 0 byte and under default_segments you see the individual split parts in subdirectories that look like this for example: 2242a4bd7d293a3930f7e38403c0b594

Uplaod and download work without any problems.

Now to my problem. If I delete the file under default, the individual parts of the file remain under default_segments and are not deleted. The storage space is not released.

In order to delete a file completely, I first have to look for the folder under default_segements under Info -> Metadata, then delete it and then the actual file under default.

Unfortunately, this is very tedious and time-consuming, especially if you have a lot of files.

David Kocher wrote to me: When deleting the manifest files for a large upload we ought to collect all segment files and delete these as well.

Now i enclosed the LOG from the Cyberduck and some Screenshots. I use Cyberduck on Windows 10 21H2 the Cyberduck-Version is 8.3.2.37449.

I have carried out the following:

1. display the file 03_LW_E63.adi incl. info because of the directory for the segments. (Cyberduck01.png)

2. after deleting the file 03_LW_E63.adi, it is gone in default. however, the associated directory in default_segments is still present and also occupies the space. (essafb41...) (Cyberduck_02.png).

3. delete the segments via delete essafb4... (Cyberduck_03.png)

4. after manual deletion everything is gone. (Cyberduck_04.png)

Many greetings

Handling the deletion of large segments when replacing a file has been revised with #14327.

[dkocher]

Large object segments are stored in .file-segments/ by default. You may want to reach out to Infomaniak support about default_segments.
