Script reports to be run from M,2 when using M2. SSD cache on volume. Same occurs for Synology_HDD_DB script as well.
cat /proc/mdstat command returns the following on my DS1621+

unused devices:
Thanks for looking into it.
@007revad commented on GitHub (Jan 5, 2024):
Looks like I'll have to setup an NVMe read cache for 1 of my volumes to see what the script is doing wrong.
@herbingk commented on GitHub (Jan 6, 2024):
Just did a quick check and confirm, by disabling the M.2 SSD cache, the warning disappears.
@007revad commented on GitHub (Jan 6, 2024):
Ok. I've done some testing and I get the warning if the scriptpath variable is empty or contains a volume# that does not exist.
If you try this test script what does it return?

@007revad commented on GitHub (Jan 6, 2024):
When you run syno_enable_dedupe.sh what does the 4th or 5th line show?
It should show the path and filename of the script, like:
Running from: /volume1/scripts/syno_enable_dedupe.sh@herbingk commented on GitHub (Jan 6, 2024):
Running from: /volume1/admin/Synology_enable_Deduplication/syno_enable_dedupe.sh
@herbingk commented on GitHub (Jan 6, 2024):
/volume1/scripts/test.sh
scriptvol: volume1
vg: vg1
md: md3
md2
WARNING Don't store this script on an NVMe volume!
@007revad commented on GitHub (Jan 6, 2024):
Strange. It doesn't do that for me.
I currently have 4 volumes:
And a SATA SSD as a read cache for volume 5.
I just noticed that you and I are somehow getting an extra md2 on the line after "md: md3" for volume1.
@007revad commented on GitHub (Jan 6, 2024):
I just ran that test script on my DS720+ which only has 1 HDD volume and I didn't get the warning or the extra md2.
@herbingk commented on GitHub (Jan 6, 2024):
md3 is my M.2 SSD cache
md2 is my RAID5 SATA SSD volume where the script is stored at
cat /proc/mdstat returns:

@007revad commented on GitHub (Jan 6, 2024):
Your seeing the same as me. md3 is the SSD cache. md2 is the HDD array.
On my DS1821+ I get this:
And this:
Digging a little deeper I see this:
I believe I've found the solution. Can you try this test script to confirm it works correctly for you.

@herbingk commented on GitHub (Jan 6, 2024):
Sure, returns no more warning:
/volume1/scripts/test.sh
scriptvol: volume1
vg: vg1
md: md2
@007revad commented on GitHub (Jan 7, 2024):
Fixed in https://github.com/007revad/Synology_enable_Deduplication/releases/tag/v1.2.17
Thank you.
@herbingk commented on GitHub (Jan 7, 2024):
It was a pleasure to me. I have to thank you for creating, maintaining and sharing these valuable scripts with us. Very much appreciated!
