P3608 ssd: lspci OK while fdisk fail to find device.

[llpyh]

My P3608 ssd seems to have some problems recently. lspci works fine and I can find /dev/nvme*n1.

However, fdisk doesn't show this device.

isdct also cannot find information about this disk.

When using fio to test, it works fine without option "direct=1" while fails with it.

Does someone knows what happened to this ssd???

ps. information in details is listed below.

Hi lpyh,

Thank you for contacting our support community. We understand your situation regarding the Intel® SSD DC P3608 Series. In order to better assist you with your situation, could you please provide the following information: Is the SSD connected directly to the motherboard? Or is it connected to a RAID controller? IS the SSD configured in a RAID array? If so, please specify which one. What is the Linux* distro you are using and the kernel version?We look forward to hearing back from you.Regards,Junior M.

1. It's directly connected to the motherboard through PCIe slot.

2. It doesn't configured in RAID.

3. My linux distro information: ubuntu 16.04 with kernel linux 4.14.0

BTW, I find that "lsblk" shows the disk information correctly, while "fdisk -l"cannot show anything about the SSD. Then typing "fdisk /dev/nvme0n1", it only shows 5GB capacity.

[llpyh]

isdct can show the ssd information, but "Inappropriate ioctl for device".
