From c5ba7a2a4dd19a2d31b8a9d52d3c4bdde78387f0 Mon Sep 17 00:00:00 2001 From: Thomas Blume Date: Thu, 2 Mar 2023 12:06:13 +0100 Subject: udev-rules: fix nvme symlink creation on namespace changes The nvme by-id symlink changes to the latest namespace when a new namespace gets added, for example by connecting multiple NVMe/TCP host controllers via nvme connect-all. That is incorrect for persistent device links. The persistent symbolic device link should continue to point to the same NVMe namespace throughout the lifetime of the current boot. Therefore the namespace id needs to be added to the link name. --- rules.d/60-persistent-storage.rules.in | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'rules.d') diff --git a/rules.d/60-persistent-storage.rules.in b/rules.d/60-persistent-storage.rules.in index 43c2060d59..76621a467d 100644 --- a/rules.d/60-persistent-storage.rules.in +++ b/rules.d/60-persistent-storage.rules.in @@ -37,14 +37,22 @@ KERNEL=="nvme*[0-9]n*[0-9]", ENV{DEVTYPE}=="disk", ATTRS{serial}=="?*", ENV{ID_S KERNEL=="nvme*[0-9]n*[0-9]", ENV{DEVTYPE}=="disk", ATTRS{wwid}=="?*", ENV{ID_WWN}="$attr{wwid}" KERNEL=="nvme*[0-9]n*[0-9]", ENV{DEVTYPE}=="disk", ATTRS{model}=="?*", ENV{ID_MODEL}="$attr{model}" KERNEL=="nvme*[0-9]n*[0-9]", ENV{DEVTYPE}=="disk", ATTRS{firmware_rev}=="?*", ENV{ID_REVISION}="$attr{firmware_rev}" +KERNEL=="nvme*[0-9]n*[0-9]", ENV{DEVTYPE}=="disk", ATTRS{nsid}=="?*", ENV{ID_NSID}="$attr{nsid}" +# obsolete symlink that might get overridden on adding a new nvme controller, kept for backward compatibility KERNEL=="nvme*[0-9]n*[0-9]", ENV{DEVTYPE}=="disk", ENV{ID_MODEL}=="?*", ENV{ID_SERIAL_SHORT}=="?*", \ OPTIONS="string_escape=replace", ENV{ID_SERIAL}="$env{ID_MODEL}_$env{ID_SERIAL_SHORT}", SYMLINK+="disk/by-id/nvme-$env{ID_SERIAL}" +KERNEL=="nvme*[0-9]n*[0-9]", ENV{DEVTYPE}=="disk", ENV{ID_MODEL}=="?*", ENV{ID_SERIAL_SHORT}=="?*", ENV{ID_NSID}=="?*",\ + OPTIONS="string_escape=replace", ENV{ID_SERIAL}="$env{ID_MODEL}_$env{ID_SERIAL_SHORT}_$env{ID_NSID}", SYMLINK+="disk/by-id/nvme-$env{ID_SERIAL}" KERNEL=="nvme*[0-9]n*[0-9]p*[0-9]", ENV{DEVTYPE}=="partition", ATTRS{serial}=="?*", ENV{ID_SERIAL_SHORT}="$attr{serial}" KERNEL=="nvme*[0-9]n*[0-9]p*[0-9]", ENV{DEVTYPE}=="partition", ATTRS{model}=="?*", ENV{ID_MODEL}="$attr{model}" KERNEL=="nvme*[0-9]n*[0-9]p*[0-9]", ENV{DEVTYPE}=="partition", ATTRS{firmware_rev}=="?*", ENV{ID_REVISION}="$attr{firmware_rev}" +KERNEL=="nvme*[0-9]n*[0-9]p*[0-9]", ENV{DEVTYPE}=="partition", ATTRS{nsid}=="?*", ENV{ID_NSID}="$attr{nsid}" +# obsolete symlink that might get overridden on adding a new nvme controller, kept for backward compatibility KERNEL=="nvme*[0-9]n*[0-9]p*[0-9]", ENV{DEVTYPE}=="partition", ENV{ID_MODEL}=="?*", ENV{ID_SERIAL_SHORT}=="?*", \ OPTIONS="string_escape=replace", ENV{ID_SERIAL}="$env{ID_MODEL}_$env{ID_SERIAL_SHORT}", SYMLINK+="disk/by-id/nvme-$env{ID_SERIAL}-part%n" +KERNEL=="nvme*[0-9]n*[0-9]p*[0-9]", ENV{DEVTYPE}=="partition", ENV{ID_MODEL}=="?*", ENV{ID_SERIAL_SHORT}=="?*", ENV{ID_NSID}=="?*",\ + OPTIONS="string_escape=replace", ENV{ID_SERIAL}="$env{ID_MODEL}_$env{ID_SERIAL_SHORT}_$env{ID_NSID}", SYMLINK+="disk/by-id/nvme-$env{ID_SERIAL}-part%n" # virtio-blk KERNEL=="vd*[!0-9]", ATTRS{serial}=="?*", ENV{ID_SERIAL}="$attr{serial}", SYMLINK+="disk/by-id/virtio-$env{ID_SERIAL}" -- cgit v1.2.3
