Raid0 drives not correctly detected on debian 12.2
by rekotc from LinuxQuestions.org on (#6FRFW)
Hello everybody,
I've recently updated a very old machine to Debian 12. This machine has a dual-boot setup with Windows 10.
The Windows system is installed on an RAID0 configuration (Intel softraid) on two physical drives, and it worked correctly before the update.
Now, when I run os-prober in order to detect the windows partition, I get the following:
Code:lsblk: /dev/mapper/isw_bjdgfgejcf_RAIDSTACKER*[0-9]: not a block deviceSo I run fdisk -l to check the situation (I hid the unrelated drives from the output):
Code:rekotc@QSTACKER:/dev/mapper$ sudo fdisk -l

The two drives are detected first as single drives, as /sdd and /sde, plus the /sde2 partition seems to be some kind of "raid" drive since it shows a 930,9G size. And then I have /dev/mapper/isw_bjdgfgejcf_RAIDSTACKER, which should be the actual raid0 configuration, but for some reason the disk is splitted into 3 different devices, with this "part1", "part2", "part3" added at the end of the device name.
Any hint about this? Thanks in advance.
