Re: [CentOS] systemd-udevd not applying ATTR to block device at boot

I suppose it would help if I posted relevant version info (sorry about that...) CentOS Linux release 7.4.1708 (Core) @ 3.10.0-693.11.6.el7.x86_64 systemd-219-42.el7_4.4.x86_64 $ modinfo virtio_scsi filename: /lib/modules/3.10.0-693.11.6.el7.x86_64/kernel/drivers/scsi/virtio_scsi.ko.xz lice

[CentOS] systemd-udevd not applying ATTR to block device at boot

Hi everyone, I have a udev rule file that contains a singular rule: SUBSYSTEM=="block", ACTION=="add|change", ENV{ID_VENDOR}=="*Google*", ENV{DEVTYPE}=="disk", ATTR{queue/scheduler}:="noop" When I use a Google Cloud instance and boot it, things work as expected and /dev/sda (a persistent disk)
