      Description

      Commit "LU-9551 utils: add l_tunedisk to fix disk tunings" added the following lines to 99-lustre.rules.

      1. Ensure block devices re-added to the system allow for large writes (LU-9551)
        ACTION=="add|change", SUBSYSTEM=="block", RUN+="/usr/sbin/l_tunedisk /dev/%k"

      However, /usr/sbin/l_tunedisk does not exist on lustre clients and resulted in dmesg:

      Oct 23 08:06:49 lmds1 systemd[1]: Started udev Coldplug all Devices.
      Oct 23 08:06:49 lmds1 systemd-udevd[1565]: failed to execute '/usr/sbin/l_tunedisk' '/usr/sbin/l_tunedisk /dev/sdb': No such file or directory
      Oct 23 08:06:49 lmds1 systemd-udevd[1161]: Process '/usr/sbin/l_tunedisk /dev/sdb' failed with exit code 2.

      Isn't this supposed to be on the server side only?
