When I try to use the Discover app I just get a spinning icon that says "Still looking..." I back up one screen and it says:
"Unable to load applications.
Please verify Internet connectivity."

But I DO have Internet connectivity. I can bring up Konqueror or Firefox and surf the web and ping various web servers.

This is probably related to the fact that when I click the Networks icon in the system tray it says:
"No available connections"

This is on a desktop PC using the wired ethernet port built-in to the motherboard.

It seems that some parts of KDE are not recognizing the existing and working ethernet connection.

Any suggestions?

I finally got Devuan to install and boot with the root partition on a RAID0 array and in pure UEFI mode. See this link to discussion on this topic in the Debian users forum:
https://forums.debian.net/viewtopic.php?t=153228

Since Devuan is essentially Debian with a different init system, the same initrd workaround also works for Devuan.

Well, I finally got it to boot. I tried all kinds of things: regenerated the initramfs a few times, tried several kernel boot options, etc. Spent many hours on it. Nothing worked. Then the thought occurred to me to try a different BIOS boot option. I had been booting the PC in pure UEFI mode. That is how I boot Windows, Artix Linux, CentOS and the Devuan install CD. I tried setting the BIOS to UEFI+Legacy mode and now Devuan boots! I don't know why the installed kernel requires UEFI+Legacy mode when the installation CD didn't, but that was the key to getting it to boot.

I followed the instructions at https://wiki.debian.org/EFIStub, created a Devuan subdirectory on the efi partition and created the /etc/kernel/postinst.d/zz-update-efistub and /etc/initramfs/post-update.d/zz-update-efistub. I noted that the file /etc/initramfs-tools/modules contains the entries

md-dev
raid0

That looked like those should be important, since I have a RAID0 array.

I verified that the mdadm package was already installed

I ran
update-initramfs -u
as instructed in https://wiki.debian.org/SoftwareRAID.

I verified that the vmlunuz and initrd.img files got copied to the efi Devuan directory.

I used efibootmgr to create a new entry in the UEFI boot menu using this command:

efibootmgr --disk /dev/md126 --part 1 -c -L "Devuan (EFI stub)" -l /EFI/Devuan/vmlinuz -u 'root=UUID=6ae760b1-58a7-4b88-8373-5342d04deba2 ro rootfstype=jfs initrd=\EFI\Devuan\initrd.img mdadm=true'

I try to boot Devuan from the new "Devuan (EFI stub)" boot selection. It acts like it almost boots. It appears to load the kernel and the initramfs, lots of messages scroll by, and then it gets stuck the same as I originally posted, because it can't find the root partition. I check /dev and the /proc/mdstat file and see that the RAID didn't get assembled and accessed.

I removed the "quiet" boot parameter so I could see more messages as it attempts to boot. Here are the last screen full that I captured:

I noticed the message about "Loading essential drivers... raid6 ..." and then more messages about raid6. Why raid6. I have raid0, or does raid6 encompass all forms?

Anyway, it looks like I am getting close to getting Devuan to boot, but I must be missing some essential kernel hook or initramfs module, or something?

Any suggestions?

I have Devuan installed on a RAID0 array. The install seemed to go ok but it won't boot. I am wondering if I can forget grub and just boot the kernel directly. I also have Artix Linux running on the same RAID0 and that is the way it works. I copied the Artix kernel and initramfs to a subdirectory on the efi partition and used efibootmgr to create a new entry in the UEFI boot menu. Artix Linux boots right up; no grub required. I'm wondering if I can do the same with Devuan?

TxLogicGuy · Installation

As I mentioned in my original post, I am trying to install Devuan on a Intel motherboard with Intel Rapid Storage Technology, sometimes called "fake RAID" in these fora. I have 2 disks configured in the BIOS as RAID0. I already have Windows 7, Artix Linux, and CentOS 8 installed and running in separate partitions on this RAID0 array. Windows uses an Intel driver to access the RAID. Artix Linux and CentOS both use mdadm.

I don't have any other disks in the system. The UEFI efi partition is the first partition on the RAID0 array. Those three OS's that I listed all have their initial boot code stored in their own subdirectories on the efi partition. All three of those OS's boot right up. The UEFI firmware obviously knows how to load and run those boot code modules, even when the efi partition is on a RAID.

I originally tried to install Debian on this machine following the instructions at the link in the Debian wiki that steve_v pointed to. I got as far as step 9, which involves booting the the install disk in rescue mode and mounting the Debian partition in chroot mode. When I do that, the install disk says that it can't find any partitions. I put a query on the Debian forum but never got an answer. So, I decided to try Devuan. It seemed to go through the install phase all right but it won't boot. That is how I ended up here.

I can't mount the Devuan partition from the initramfs prompt and chroot into it because the RAID partitions are not visible at that point.

I tried booting the install disk in Rescue mode but discovered that the
modprobe raid0
mdadm --assemble --scan
trick I posted earlier doesn't work when booted in that mode. Apparently it's not loading the same kernel, or the same kernel options, as when booted in normal install mode.

This is turning out to be much more difficult than I anticipated.

Well, that worked only up to a certain point. The Devuan install seemed to go ok but it won't boot. I now have a new entry in my UEFI boot menu, I select it, I get a grub menu, but Devuan doesn't start. I get a blank screen for about 30 seconds or so then I get this:

mdadm: error opening /dev/md?*: No such file or directory

(initramfs)

UUID=6ae760b1-58a7-4b88-8373-5342d04deba2 is the UUID of the partition where Devuan was installed, so that is correct.

I think the clue is probably this:

mdadm: error opening /dev/md?*: No such file or directory

It appears that some kernel component is not getting loaded which would allow the RAID array to be recognized.

Any suggestions?

Thank you ralph.ronnquist for the pointer to https://raid.wiki.kernel.org/index.php/RAID_setup !

It turns out that all I had to do was run the installer up to the point where it runs the partitioner, back up and drop to a command prompt, and type
modprobe raid0
mdadm --assemble --scan

Now when I go back into the partitioner it shows my RAID0 array and all the existing partitions.

I have an Intel DH77KC motherboard. This board has BIOS RAID, what Intel calls Intel Rapid Storage Technology, and what in these fora is often called SATA RAID or "fake RAID". I have 2 disks configured in the BIOS as RAID0. I already have Windows 7, Artix Linux, and CentOS 8 installed and running in separate partitions on this RAID0 array. I would like to give Devuan a try. I booted a CD with devuan_chimaera_4.0.0_amd64_netinstall.iso; but, when I get to the "Partition disks" step it doesn't show the existing RAID array but instead the individual disks.

I tried adding dmraid=true or mdadm=true to the boot parameters but neither one helped.

Windows 7 uses an Intel driver to access the RAID. Both Artix Linux and CentOS use mdadm.

I booted the CD in expert mode and did some exploring of the install environment from a command shell. I tried executing
find / -name 'mdadm*'
and got this:
/cdrom/pool/DEBIAN/main/m/mdadm
/cdrom/pool/DEBIAN/main/m/mdadm/mdadm_4.1-11_amd64.deb
/cdrom/pool/DEBIAN/main/m/mdadm/mdadm-udeb_4.1-11_amd64.udeb
/tmp/mdadm.conf
/sbin/mdadm
/run/mdadm

So, mdadm is already on the CD. The /tmp/mdadm.conf file caught me attention. Its contents are:
ARRAY metadata=imsm UUID=f46ce314:c874c458:5630027e:d4375317
ARRAY /dev/md/WD1TBRAID0 container=f46ce314:c874c458:5630027e:d4375317 member=0 UUID=58b9905f:2a773399:518dbd70:7b52bdc0

Aha! WD1TBRAID0 is the name of my RAID array, so Devuan is recognizing the RAID to a certain extent. I just need to find some way to make it read the partition table (GPT) and find the existing partitions.

Is there some magic kernel boot parameter I can enter, or some hocus-pocus commands I can enter from a command shell to make it make use of mdadm, and whatever else might be required, to make Devuan understand and use my RAID array?

Any suggestions will be appreciated.
