I have worked with Dell Poweredge servers around 15 y ago. These had PERC hardware RAIDs able to completely do the whole job without any help from the OS. The configured RAID devices were seen by the kernel as individual disks. After a few years working like this I configured the PERC so as to show every disk individually (therefore no RAID), and managed software RAIDs using mdadm. md RAIDS, not dm RAIDS. dm stands for device-mapper, which also means Logical Volume Manager. On the contrary of what is said in the Debian document, I found LVM (dm RAIDs) not much more usefull than md and overly complex. On the other hand, mdadm also is not a piece of cake but I can find my way with it and I have developped a graphics monitoring tool for it, actually a little web server displaying the status of all the host's md RAIDs. Hi, I'm interested about this web server thing is it packaged? Not packaged. Debian packaging is something I was never able to achieve and I prefer devoting my time to more fruitfull trasks, given my skills. I can send you diskweb.tgz, the size of which is 16K. It is trivial to build. It monitors both md RAIDs and the level of occupation of the filesystems. RAID data is read from devices' representation in /sys/devices/virtual/block, and the display is made attractive by the use of colors and svg graphics. I wrote this more than a dozen years ago and never touched it since that time. It's running on our home Desktop. Note that the location /sys/devices/virtual/block is not granted to stay the same place in the future, but this location is easy to change in the source in case kernel people change their mind. If more people are interested I might put it on Devuan git. -- Didier ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

Hi Frazier,
A couple nights ago I went through similar nonsense on a newly
purchased refurbished Dell Insperon 3721 laptop. I used a different
distro (Void) and I didn't have hardware Raid. Also, my setup wouldn't
recognize my Void install DVD in UEFI, and wouldn't boot it in Legacy,
which is a little different. But I think we're still in the same
ballpark.
On my machine, SETUP is F2 several times before and during the Dell
logo. Boot choice at boot time is F12 several times before and during
the Dell logo. Obviously, your computer might have different buttons
for this stuff.
So I created a Void installer thumb drive, using
cp void.img /dev/sdWhatever, taking care that I got the thumb drive and
not my hard drive (which would be a big oops). I stuck it in the USB
slot, rebooted, F2 and set the machine to boot from UEFI, not Legacy,
but to leave Legacy enabled. I then exit and saved and of course it
booted windows. So then I powered off, powered on, and pressed F12
several times. When the F12 screen came up, under UEFI choices I had
Windows boot selector or whatever it's called, but now I also had USB
, which I chose and continued. It booted my thumb drive.
NOW, I'm booted into UEFI, so the installer thumb KNOWS it's in UEFI
and installs a UEFI installation. I just did a typical install, setting
the bootloader to /dev/sda and making the EFI partition /boot/efi. I
rebooted, pressed F12 again, and bang, up came Linux.
My story is just an anecdote, and your mileage may vary. But I have a
feeling that booting the thumb by way of UEFI was the key distinction.

If you changed from RAID to AHCI, didn't that trash your Windows? The

I'd ask the guys you bought it from before busting open the box.
