Hi,
We have run the below command and it runs without any error.
./poseidonos-cli device scan

But, the below command does not fetch any NVMe from the hardware.
./poseidonos-cli device list --unit

Checked the PoseidonOS is running by the command below;
ps -ef | grep poseidonos | grep -v grep

The below command shows two drives in the hardware:
fdisk -l | grep nvme

Please help!!!
Thanks in advance

Hi,
I think you are missing run script/setup_env.sh to bind userspace driver.
can you check this?

[aagi-girish]

Hi,
We ran the "script/setup_env.sh" and then scanned for the available disks. But the result of bin/poseidon-cli device list is as attached below.

[so931]

Did you run poseidon os?
Before run poseidon-os cli, need to run the poseidonos first.

[aagi-girish]

Thanks. But the NVMe was not listed yet. Any suggestions would be of great help.

[so931]

Can you attach the log "/var/log/pos/pos.log"?

[aagi-girish]

Attached. Thanks.
pos.log

Currently, only 512 sector size device is supported in poseidonos.
You can check your device's sector size use the following steps.

1. make udev_uninstall
2. lib/spdk/script/setup.sh reset
3. apt install nvme
4. nvme id-ns -H /dev/nvme0n1 | grep LBA Format.

Can you share the result of above command?

[aagi-girish]

Thanks. The output you requested is provided below.

[so931]

You can change sector size using below command.
$ sudo nvme format /dev/nvme0n1 -l 0
$ sudo nvme format /dev/nvme1n1 -l 0
And also, you need a minimum of 3 same NVMe devices to create an array.

Thanks. It worked. Hope to see compatibility for sector size 4k as well.
