Man page provides no clue how to interpret NVMe error log

[xypron]

sudo smartctl -a /dev/nvme0

reports a lot of errors

But unfortunately neither the smartctl output nor the man pag provides any clue how to interpret this output.

I think the documentation should provide both a description of each of the error log columns as well as links to the documents describing the values seen here.

sudo nvme error-log /dev/nvme0

provides a bit more information

The nvme-cli tool is available here: ​https://github.com/linux-nvme/nvme-cli.

As both smartmontools and nvme-cli are under GPLv2 it should be easy to just copy the status field texts to smartmontools.

Here are some commands that provoke one of the errors I observed:

sudo nvme sanitize-log /dev/nvme0
NVMe status: INVALID_LOG_PAGE: The log page indicated is invalid. This error condition is also returned if a reserved log page is requested(0x2109)

sudo nvme self-test-log /dev/nvme0
NVMe status: INVALID_LOG_PAGE: The log page indicated is invalid. This error condition is also returned if a reserved log page is requested(0x2109)

sudo nvme endurance-log /dev/nvme0
NVMe status: INVALID_LOG_PAGE: The log page indicated is invalid. This error condition is also returned if a reserved log page is requested(0x2109)

sudo nvme ana-log /dev/nvme0
NVMe status: INVALID_LOG_PAGE: The log page indicated is invalid. This error condition is also returned if a reserved log page is requested(0x2109)

sudo nvme changed-ns-list-log /dev/nvme0
NVMe status: INVALID_LOG_PAGE: The log page indicated is invalid. This error condition is also returned if a reserved log page is requested(0x2109)

sudo nvme telemetry-log /dev/nvme0 -o foo
NVMe status: INVALID_LOG_PAGE: The log page indicated is invalid. This error condition is also returned if a reserved log page is requested(0x2109)

smartctl -l error ... now prints an error message:
