DS925+ DSM 7.4-90075 requires m2_pool_support=1 for M.2 Storage Pool

[sashved2020-ai]

Hi
First for all thanks, for maintaing this script
I found something intreing while working with DS925+ with model DSM 7.4-90075. i had 2 ssd disk and couldt use them becouse of they wasnt for Synology_HDD_db v3.6.132. There was a lot of old exploits which hepls to dismand , but i didint found anywhere exploits for version 7.4. the old methods didnt work for this model. I ran:
/opt/syno_hdd_db.sh -f
The script reports:

• Support disk compatibility already disabled
• NVMe support already enabled
• M.2 volume support already enabled
  However Storage Manager still refused to create an M.2 Storage Pool and displayed:
  "This drive has not been tested or validated for M.2 SSD storage pools."
  I inspected the runtime files and found:
  /run/synostorage/disks/nvme0n1/m2_pool_support = 0
  /run/synostorage/disks/nvme1n1/m2_pool_support = 0
  After changing both values to:
  echo 1 > /run/synostorage/disks/nvme0n1/m2_pool_support
  echo 1 > /run/synostorage/disks/nvme1n1/m2_pool_support
  Storage Manager immediately allowed creation of the Storage Pool.
  To make it persistent I currently execute those commands at boot via Task Scheduler.
  Maybe DSM 7.4 overwrites m2_pool_support after your script runs?
  Hope this helps

You should always run syno_hdd_db.sh with the -n option. And the -f option you used causes the issue you experienced.

/opt/syno_hdd_db.sh -n

or if syno_hdd_db is scheduled

/opt/syno_hdd_db.sh -ne

That makes sense, I was assuming DSM 7.4 was resetting m2_pool_support, but still I did it but in worser way
