I may have missed it somewhere, what OS (and version) are you using?
Also are you accessing the nvme device e.g. /dev/nvme0n1 raw or via
partition or filesystem?

Subject: Problems writing to intel P3700 NVMe drive
I am having problems with writing to an intel P3700 NVMe drive on a ARM
based platform and I would appreciate any help in debugging this problem.
Here are my experiments and observations so far:
- The drive is usable for read operations and I can run fio (randread,
etc) but I cannot write to it.
- Other manufacturer's NVMe drive can be inserted into this platform and
I can write to it
- I can insert the intel P3700 into an x86 host and I can perform write
- I have tried using the nvme-cli
(https://github.com/linux-nvme/nvme-cli) tool and have read the error codes
from read. It just shows 'WRITE_FAULT' which is not very helpful.
- I have looked at the SmartLog reports and the 'Critical Warning'
is 0, i.e. the device is not in Read-Only mode
- I have updated the firmware using the intel SSD-DataCenterTool and
updated the firmware on the drive the latest available version.
The updated drive works fine on x86 platform.
I think there is some combination of the platform and drive that is causing
the problem. Can anyone offer pointers on how to debug this?
