The Synology needs to restart. Type yes to reboot now. Type anything else to quit (if you will restart it yourself).

After running syno_enable_m2_card.sh, E10M20-T1 with its storagepool came back online!

After the last DSM update I discovered you can set a "pre-task" to a triggered scheduled task. This will make sure that "syno_enable_m2_card.sh --model=E10M20-T1" runs before syno_hdd_db.sh

But I'd still need to reboot after a DSM update has finished and booted up.

Need to download dtc Do you want to download dtc? [y/n]

This is strange. Syno_hdd_db should have installed dtc, and when syno_enable_m2_card updated it should have included /bin/dtc

[RozzNL]

Changed the taskscheduler to include the pre-task, thanks. Is there any way i can help you further to prevent this happening again or to others?

What is dtc? saw in your github comment this was applicable so said YES to install.

[007revad]

dtc (device tree compiler) is a tiny linux cli program used to decompile and compile device tree blobs, which allows adding device information without compiling a new kernel. Synology models from 2020 onwards that use a CPU that Synology hadn't used before all use a device tree blob named model.dtb. To enable E10M20-T1, M2D20, M2D18 or M2D17 on NAS models that don't already support them the script needs dtc, which is not included in DSM.

I'm trying to think how to prevent the same thing happening to other people.

Before this 7.2.2 update all was well, i did however use the hdd_db at shutdown instead of at bootup, but it should not matter i think?
