nvme drives

I have these on my new computer. I can partition the nvme scsi drive with parted but parted can't handle the other drive on the machine. Has archlinux got a separate tool to take control of nvme drives the way parted does?

Hi. What are the other drives in question? //Torxed On 10/3/22 09:02, Jude DaShiell wrote:

Hello, And what? what you have pasted is just showing one nvme device with two partitions and there is nothing unusual there in my opinion. W dniu 3.10.2022 o 17:17, Jude DaShiell pisze:

Hi. Correct, both /dev/sda and /dev/nvme0n1 are normal devices and parted can handle both. The others are not really block devices expected to be dealt with using parted (or equivalent programs). //Torxed On 10/3/22 17:19, Michał Zegan wrote:

You made me curious: is there any documentation on this? I was under the impression that nvme was just another (storage) interface and that EFI partitions were just fat32 partitions. Now it sounds like there is something special going on with nvme and efi? Mvg, Guus Snijders

By any chance is the disk controller in the EUFI/BIOS set to RAID or Intel rapid storage technology? Try changing it to ACHI and see if that resolves your issue. On Mon, Oct 3, 2022, 12:02 AM Jude DaShiell wrote:

rather not ahci. nvme and ahci are two different things. here on my computer i can enable or disable something like this and it will probably either present two nvmes as one or two nvmes as two W dniu 3.10.2022 o 17:59, nhasian@gmail.com pisze:

That needs sighted people to even look at those settings let alone adjust them. Jude <jdashiel at panix dot com> "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Hello, The kernel should be able to detect those remapped nvme drives and report them in the ahci sysfs tree. cat /sys/bus/pci/drivers/ahci/*:*/remapped_nvme This command should report a number greater than 0 if there is such a remapped nvme. Since the nvme is listed in the lsblk output, there should be no remapping occuring, though. What drives do you expect the machine to have? Your output lists one unpartitioned scsi/sata drive as /dev/sda, one nvme drive as /dev/nvme0n1 including three partitions, one optical drive as /dev/sro, and some zram (compressed ram). parted should be able to work with both sda and nvme0n1. I think the -l option for parted should list all drives and partitions it can access. parted -l -- ProgAndy Am 03.10.22 um 18:52 schrieb Jude DaShiell:

If any disk partitions were changed then the kernel needs to be informed to update its internal map - this is usually done by calling partprobe. I dont use parted so it may already be doing that, but mentioning in case its helpful. I am unclear what the problem is exactly. regards, gene
