I tested it on my DS1821+ and the script works. Analyze shows saving 4 TB. Now set to automatic and hope it does something

UPDATE: script also works fine on DS1821+ and DS920+ with DSM 7.3.2-86009

The script (and syno_hdd_db.sh) seems to run successfully for me on a DS925+ with that DSM version, with 4GiB of RAM and two Western Digital Red Plus 8TB disks, with --tiny --hdd, but after rebooting and trying in a clean browser session I still cannot get the "Configure data deduplication" option to appear. Unfortunately I just started using this system, cannot say whether it would have worked on an earlier DSM version, so I don't know if there's something else I'm missing.

FWIW, full output of sudo -s ./syno_enable_dedupe.sh -c:

Synology_enable_Deduplication v1.4.32
DS925+ DSM 7.3.2-86009

StorageManager 1.0.1-1100

Using options: -c
Running from: /volume1/scripts/Synology_enable_Deduplication-1.4.32/syno_enable_dedupe.sh

NAS has 4 GB of memory.

Btrfs Data Deduplication is not enabled.

Tiny Btrfs Data Deduplication is enabled.

Dedupe config menu for HDDs and 2.5" SSDs is enabled.

Backup file is okay.

Don't forget you need the scheduled task that runs them on reboot...

@Khazmadu Do you only have HDDs?

My DS821+ is still on DSM 7.3.1 but after it updated to Storage Manager 1.0.1-1100 my HDD volume no longer had the deduplication option, but my NVMe volume still does. So I suspect I just need to do the storage manager edit differently for 1.0.1-1100 and later.

After comparing Storage Manager 1.0.0-01026's storagepanel.js to 1.0.1-1100's storagepanel.js I realised nothing has really changed in Storage Manager. So I tried something really simple and then rebooted and it worked!

I'll update the script tomorrow.

@hawkeye73 Do your DS920+ and DS1821+ both have 16GB or more memory?

I suspect the problem is only for those with 4GB or more but less than 16GB of memory.

Correct:

DS920+ -> 20 GB
DS1821+ -> 36 GB

@007revad I have only HDD volumes. I have NVME SSDs but those are used as cache drives.
It would be great if you could update the script. It has been very useful for me so far.

Thanks, I'm not sure that was even the problem in the end. I installed the new version twice, rebooting every time. No errors or anything, but it still didn't work.
I then rebooted a third time, actually for a different reason but after that it finally showed up and is now working again.

I've rebooted once via the script, and now 2 times via the UI - I still don't see the option.

If you need any logs etc let me know - thanks!
