Hi,
i've ported my raid to a new hardware.
Within the old omv5 system everything works fine.
After moving to new hardware the raid is missing sda disk on every boot.
I'am able to readd that drive and snyc the array afterwards. But on next boot the disk is leaving the raid again.
The first system was an HP ProLiant Microserver 40N.
The new system is based on FANTEC SRC-3168X07.
From the hardware site the main difference is that the new system has got backplanes and the main drive is a m2 disk instead of a ssd.
