OMV4 with SATA PCI-e adapter doesn't boot

Hello,

I make a new OMV 4.19 NAS on a optiplex 390. My nas works very well with only 2 SATA harddrives: one SSD with the OMV system and other one with datas.
Now, I want to add a new SATA datas harddrive but my motherboard has only 2 SATA slots.

So, I bought 2 differents SATA adapter (PCI-E X1) with the same effect: As I physicaly attached a SATA drive on the card adapter and reboot the NAS, my NAS doesn't want boot anymore (GRUB doesn't launch).
I precise, if I attach the SATA drive AFTER the boot, there is no problem! I can see and mount the drive from the Web GUI or SSH.

My Sata adapters are:
- Marvel 88SE9125 rev1.1 (Hightpoint Rocket 620)
- ASMEDIA ASM1061

I performed this installation:

echo "deb http://deb.debian.org/debian stretch-backports main contrib non-free" >> /etc/apt/sources.list
apt-get update
apt-cache search linux-image-4
apt-get -t stretch-backports install linux-image-4.19.0-0.bpo.5-amd64 firmware-linux-free

Do you know why my NAS doesn't want to boot with a disk physically attached to my SATA adapter?
I think there is probably a way to boot by changing "/etc/fstab" but I don't know how to proceed...

Thanks for any help

Hello,

Nobody to help me?

Perhaps, I'm not in the correct section of the forum? If a kind administrator can move my thread in the correct section, I would be grateful. Thanks

Thank you but it seems it's a more a software issue with grub or something like that because I have the same issue when I test with DVD drive and the first data HD drive disconnected.
My second HD drive consummes only 2.5W. Any other idea?

Hello Macom,

I succefully run a update-grub as mentioned but no more change after a reboot.

Eventually, I run boot-info-script after the grub update: bootinfo result

How to debug/trace my boot sequence? Because I think my grub doesn't launch at all when my second hard drive is attached to my sata adapter. Why? I don't know but if a get a log I will performed a more precise search.
