Many thanks for your patience and explanation.

I will now progress as I mentioned (let OpenPLI take care of trash management) and keep an eye on things. 

Indeed I find it strange. While it is an Octagon, the image for XP1000 has always been used as it is the same product just a different label

It is old but it works, I've been using OpenPLI for years with no issues.... (so far !)

So to check and test I bought a new SansDisk 128GB USB stick and have used that to make recordings. It works.

NOTE: both storage devices were tested with Linux Mint's disk utilities, no issues. But over the years my experience with storage is that it works until it doesn't !!!! (hence back ups).

But the new USB stick also shows the same problem, slowly declining free space. About 0.5GB for a 3.3GB .ts recording. 

So a series of systematic tests were carried out. The first with Linux Mint and stick, the second series with the sat tuner.

The initial testing of the USB stick was done with Linux Mint running on a laptop and stick connected directly with USB

I use Mint's file manager (Nemo) to check properties and move the 3.3GB file to the stick and delete it.

Start with an empty stick

121.4GB free and 1.1GB used, and it is a ext3/est4 file system type

Move a 3.3GB .ts file to stick

118.1 GB free and 4.4GB used

Delete file

121.4GB free and 1.1GB used, perfect result

This was done several times, the numbers never change. Everything seems fine.

There are several ways to do a similar test with the Sat tuner.

The stick is accessed via the sat tuner using an IP address (i.e. sat tuner acts as a server)

Here the process is the same as using the laptop as noted above. The results are very different, they are reported via the Linux Mints file manger

Start with empty stick

121.4GB free and 1.1GB used and file system is cifs.

Move the same 3.3GB .ts file to the stick with Linux's file manager

117.4GB free and 5.1GB used

delete the file via the file manager (need to be sudo to do that), also deleted from the sat tuners trash folder

120.7GB free and 1.8GB used  (already some capacity is disappearing)

The second method uses OpenWebif to delete the files and "Box Info" to report status

NOTE: the reported status via OpenWebif "Box info" and the Enigma menus  show quite different results for an empty unused stick or even one with recordings on it. Also a reboot was carried out to ensure everything was starting from the same level.

Status report: 113.1GB free via OpenWebif "Box Info" and 116.8GB via the tuners user menus

A 3.3.ts file was copied to the sat tuner "movie folder" via the Linux mint file manager

108.7 free (OpenWebif - "Box info")

delete the file via OpenWebif and further deletion from Trash with OpenWebif

111.8GB free

These steps were carried out several times and the free capactiy drops step by step. A reboot restores the starting condition.

My increasing suspicion (no proof) is that OpenPLI might be using the external storage in some non visible way.

So the next step is do no manual delete and let OpenPLI take care of emptying trash.

To that end the default values seem fine (minimum 40GB and 8days old are dumped)

But I now changed the background delete which seems to default on a, for me non existent, internal HDD to "everywhere"

 I know of nothing else I can do, now monitor the situation to see if OpenPLI really does manage the trash.

Sorry for the long post.....

Thanks for the heads up. The files concerned are .ts files of recordings.

When I no longer need the recording after viewing it I delete it using OpenWebif

But I then had habit of emptying the trash can on a regular basis, also via OpenWebif. Emptying the "Rubbish bin" is normal practice in Linux Mint for example.

I access the sat tuner remotely hence the use of OpenWebif, works very well (timer programming, downloading recordings, deleting them. etc). 

But over a few months I noticed I had lost about 100GB capacity from a 250GB HDD and even one fouled up recording, a reboot cleaned things up. 

My current setup is "Remove from trash after 8 days" and "Keep 40GB for recordings". 

But from your comments it seems the best approach is to let enigma take care of trash management.

I am running OpenPLi 9.0-release (2024-10-11-release-9.0). Recordings are made on a USB connected HDD to the sat tuner. (An Octagon SF8)

However deleting the recording using the OpenwebIF the amount of free capacity slowly decreases with each delete. about 0.5GB for a 4GB recording).

On rebooting the capacity is restored back to normal. 

There seems to be nothing wrong with the HDD or even a USB stick the same effect is seen.

On checking the storage with a Linux Mint laptop and the USB storage attached directly (no Sat tuner) worked perfectly.

So the issue seems to be in the Sat tuner / OpenPLI system.

I even tried accessing the USB storage when connected to the sat tuner directly (no OpenWebIF) from the Linux Mint file manager (nemo) to move and delete files.

The same slow decrease in capacatity is seen.

I can live with it as a regular reboot resets the system so to speak. But I would like to understand what is going amiss.

Any ideas?
