SOLVED: How to enable Intel Software RAID

[Ulysses_]

Windows can see 2 SSD drives as a RAID-0 set and so can Linux Mint. This is Intel Software RAID where you specify the drives in the EFI settings. How do you add support for it in Debian? Tried this:

sudo apt-get install dmraid dmeventd

Debian can now see the partitions of the RAID-0 set but not the data inside. Are some more packages needed?

Attaching the list of packages installed in Mint when RAID-0 works, that are not installed in Debian.

Debian can now see the partitions of the RAID-0 set but not the data inside.

Can you elaborate ? Please show us.

Also the file manager does not have any entry on the left for these partitions, only the partitions on the other drive, the hdd.

[Ulysses_]

Got the list of packages that Peppermint adds to Debian. This list has the following packages in common with the above list that Mint adds to Debian. So it's one or more of the following packages that is missing if any. EDIT: Repeated with Ubuntu which is yet another Debian derivative where this particular RAID works by default, and narrowed down the common packages added by all 3 distros.

Where is the config stored for this RAID?

[p.H]

The configuration for fake RAID is usually stored in the on-disk metadata.

What does blkid report about these /dev/mapper/isw_*_Volume1p* partitions (as root) ?

Code: Select all

blkid /dev/mapper/isw_*_Volume1*

Are ntfs-3g and dosfstools installed ?

[Ulysses_]

Yes they are both installed and here is the output of blkid:

sudo blkid /dev/mapper/isw_*_Volume1*
/dev/mapper/isw_baaeiihdeg_Volume1: PTUUID="16a493ca-f396-47ce-8ea4-6bf101b46e1e" PTTYPE="gpt"

[Ulysses_]

Tried installing all the packages in the above list, minus the ones that produce an "Unable to locate package" error as they are in a different repo.

Result is the same: can't see the data. What do you make of this? Blob required that only Ubuntu repos have? Default dmraid config is wrong for this hardware?

[Ulysses_]

These are the packages excluded because they are not in the Debian repo. Add any?

[p.H]

Weird, blkid does not show any partitions. Could it be that the kernel did not create the device nodes for the partitions ?
I don't know how dmraid manages partitions in fakeRAID arrays. Maybe you need kpartx.

[Ulysses_]

This stackexchange advise on adding Ubuntu repos to Debian is worrying. Should we exhaust config first and other possibilities before taking the plunge? Kpartx is available in Debian and installed but kpartx-boot is not.

[Ulysses_]

Sorted. Kpartx is the missing package, on top of dmraid and dmeventd. But an extra manual step is needed:

sudo kpartx -a /dev/mapper/isw_baaeiihdeg_Volume1

What is the proper place to put this in the initialization scripts?

[p.H]

I guess kpartx should be run in some device-mapper or udev rule triggered when the array is activated.
But that's weird because according to dmraid's manpage, it should activate partitions on the RAID set by default unless the -p|--no-partitions option is given.
