#5480 NVMe drives/partitions not detected

[Aria Bamdad]

Hi,
Running under SLES 15, webmin "Partitions on Local Disks" does not display any of the NVMe device partitions at all. Similarly the "SMART Drive Status" module does not allow you to select any NVMe drive. Any file system on these devices do show up on modules that show file systems or software RAID volumes.

My NVMe devices appear as such :

testsys:~ # l /dev/nvm*
crw------- 1 root root 244, 0 Feb 7 07:59 /dev/nvme0
brw-rw---- 1 root disk 259, 1 Feb 7 07:59 /dev/nvme0n1
brw-rw---- 1 root disk 259, 3 Feb 7 07:59 /dev/nvme0n1p1
crw------- 1 root root 244, 1 Feb 7 07:59 /dev/nvme1
brw-rw---- 1 root disk 259, 0 Feb 7 07:59 /dev/nvme1n1
brw-rw---- 1 root disk 259, 2 Feb 7 07:59 /dev/nvme1n1p1

Thanks,
Aria

Do those partitions show up in the /proc/partitions file?

[Aria Bamdad]

Hi Jamie,

Yes, the sure do:

testsys: # cat /proc/partitions
major minor #blocks name

259 0 500107608 nvme1n1
259 2 500106567 nvme1n1p1
259 1 500107608 nvme0n1
259 3 500106567 nvme0n1p1

[Jamie Cameron]

Does the base device nvme0 show up in /proc/partitions though?

[Aria Bamdad]

The base device is nvme0n1 for the first drive and nvme1n1 for the second. Each is a Samsung 970 PRO SSD 512GB. They are both installed in an Asus Hyper M.2 expansion card supporting 4 NVMe drives. Thanks.

[Jamie Cameron]

So on the "Partitions on Local Disks" page, does the NVME disk not show up at all? Or does it appear, but have no partitions?

Also, what output do you get if you run parted /dev/nvme0n1 unit cyl print

[Aria Bamdad]

Hi Jamie,
The Partitions on Local Disks page only shows the SATA devices and nothing else. The NVMe devices/partitions are not listed.

The output of the parted command is:

Model: NVMe Device (nvme)
Disk /dev/nvme0n1: 62260cyl
Sector size (logical/physical): 512B/512B
BIOS cylinder,head,sector geometry: 62260,255,63. Each cylinder is 8225kB.
Partition Table: gpt
Disk Flags:

Number Start End Size File system Name Flags
1 0cyl 62260cyl 62260cyl raid

Thank you.

[Jamie Cameron]

On the configuration page for the Partitions on Local Disks module (the gear icon), what do you have the Partition management command option set to? The best mode is Choose automatically .

Also, what does that same parted command output when run on a non-NVME disk?

[Aria Bamdad]

Configuration page for partition management command is set to Choose automatically.

Parted command on /dev/sda:

# parted /dev/sda unit cyl print

That also looks fine... which Webmin version are you running there?

Also, are you logged into Webmin as the root user?

[Aria Bamdad]

Jamie. I have to apologize. I opened a few bug reports together and wrongly assumed both systems I was working on were running the latest 1.973 release. This and another but I reported (which I will try to close) were running on a 1.850 release. I upgraded to 1.973 and both problems are fixed. I am sorry to have wasted your time.

[Aria Bamdad]

Actually, the other bug was relating to iptables and it is correctly reported for 1.973 so just this one is incorrect and can be close. Thank you again.

[Jamie Cameron]

Ok, that would explain it!
