Re: [systemd-devel] 60-persistent-storage.rules: add NVMe disks and partitions (again)

[Per Bergqvist]

Hej, Seems like nobody thinks using the scsi_id for NVMe drives is a good idea so the alternative must be to introduce a new nvme_id utility. Please find a patch (relative 2.19) to add this. It is using native nvme ioctl to get the model, serial and firmware revision info. To apply: patch -p0 < nvme_id.patch aclocal automake ./configure  The resulting entries in /dev/disk/by-id will look like: lrwxrwxrwx 1 root root 13 May 15 15:34 /dev/disk/by-id/nvme-INTEL_SSDPEDME400G4_CVMD43750011400AGN -> ../../nvme1n1 lrwxrwxrwx 1 root root 15 May 15 15:34 /dev/disk/by-id/nvme-INTEL_SSDPEDME400G4_CVMD43750011400AGN-part1 -> ../../nvme1n1p1 lrwxrwxrwx 1 root root 15 May 15 15:34 /dev/disk/by-id/nvme-INTEL_SSDPEDME400G4_CVMD43750011400AGN-part2 -> ../../nvme1n1p2 lrwxrwxrwx 1 root root 13 May 15 15:34 /dev/disk/by-id/nvme-INTEL_SSDPEDME400G4_CVMD43750013400AGN -> ../../nvme0n1 lrwxrwxrwx 1 root root 15 May 15 15:34 /dev/disk/by-id/nvme-INTEL_SSDPEDME400G4_CVMD43750013400AGN-part1 -> ../../nvme0n1p1 lrwxrwxrwx 1 root root 15 May 15 15:34 /dev/disk/by-id/nvme-INTEL_SSDPEDME400G4_CVMD43750013400AGN-part2 -> ../../nvme0n1p2 BR Per

Well, nothing changed really: we'd like to remove scsi_id from systemd/udev upstream. Please ask sg_utils to pick it up instead. We'll continue to support the status quo for a while longer, but it can't stay this way, and we shouldn't add new features to it while it's in limbo. Lennart -- Lennart Poettering, Red Hat
