I looked some more at this Terramaster RAID box and it is a closed system with
its own OS. Not something I can install my own OS on. :(
So I ask:
is there a "bare metal" RAID1 box out there I can install AlmaLinux on?
Accordance makes standalone internal RAID 1 subsystems (OS independent).
I've used them in the very very distant past.

IMHO, that may be what you really need.
The ARAID system will appear as a single drive. It is a "closed" firmware, like
most anything of this type. At the end of the day, you probably don't care.
It's a "singular drive" that just so happens to mirror to two drives.

Would hardware hit the same problem? the Terramaster looks like it is
hardware RAID?
Hardware RAID for ESP partitions requires that the EUFI firmware to understand
how to talk to the hardware raid device. If the EUFI doesn't have the right
driver it will try to talk to the hardware raid as a raw device in a different
way and it goes to pot. [You would think that server hardware would be built
to do this out of the box, but I have had a couple where hardware raid was
only supported to boot non-EUFI or required the EUFI to be on a separate drive.]

Hi Jack,
I'm sorry to bother you during holidays.
I encountered a strange problem installing AlmaLinux 9.1 on a RAID1
(MDADM) with the current configuration:
- /boot/efi on md125
- swap on md126
- / on md127
My limited understanding is that RAID on EFI has been something of a hack
as the backing store that EFI uses is a slightly modified VFAT. What
happens is that there is some code to 'clone' the data across but it
isn't really RAID1. My guess is that something in the 9.1 kernel broke
that hack. Could you try CentOS Stream 9 kernel (you can install that
with your existing Alma or Rocky system) and see if the problem still
occurs? If it does then it is a bug that needs to be tracked upstream at
bugzilla.redhat.com <http://bugzilla.redhat.com> and if it doesn't then
it should have been fixed in an upcoming kernel. You could continue to
then use the CS9 kernel until whatever works in Alma/Rocky 9
disks are 2 SSD MLC Type.
After the installation, if I reboot the system I get:
"md: md125 stopped" (it is printed many times like in a loop)
alternated with:
"systemd-shutdown[1]: Not all MD devices stopped, 1 left
Stopping MD Devices
Stopping MD /dev/md125 (9:125)"
and the system hangs on this loop until I cut the power.
I encountered this issue on my Workstation with Asus Prime Z490-A /
i9-10850k.
I tried with another workstation that runs on Asus Prime Z370-A / i7
8700K, to exclude bad SATA controller and bad cables.
Also on the second workstation the problem is found.
I tried to replicate this using 9.0 ISO. The problem does not occur
until I update to 9.1
I tried also with 8.7. No problem here.
I tried also RockyLinux 9.1 and got the same problem but with different
messages:
"block device autoconfig is deprecated and will removed"
alternated with:
"blkdev_get_no_open: 270 callbacks suppressed."
To stop the machine I need to cut the power.
I tried also Debian 11.5 without problems.
So seems that the problem is 9.1 related. Actually I can't test the same
with RHEL 9.1 but probably the problem will occour also on RHEL 9.1
There is a way to fix this or I should wait an upgrade?
Thank you in advance.
