The further same command would fail. This behavior is unfriendly to scripts since the script has no idea why exactly the second same command fails.</p> <p>By contrast, setting "disabled" would always success. The different behaviors of "disabled", "enabled" and "shutdown" is inconsistent thus confusing.</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre># lctl set_param mdt.*.hsm_control=enabled mdt.lustre0-MDT0000.hsm_control=enabled # lctl set_param mdt.*.hsm_control=enabled error: set_param: setting /proc/fs/lustre/mdt/lustre0-MDT0000/hsm_control=enabled: Operation already in progress # lctl set_param mdt.*.hsm_control=disabled mdt.lustre0-MDT0000.hsm_control=disabled # lctl set_param mdt.*.hsm_control=disabled mdt.lustre0-MDT0000.hsm_control=disabled # lctl set_param mdt.*.hsm_control=shutdown mdt.lustre0-MDT0000.hsm_control=shutdown # lctl set_param mdt.*.hsm_control=shutdown error: set_param: setting /proc/fs/lustre/mdt/lustre0-MDT0000/hsm_control=shutdown: Operation already in progress </pre> </div></div> <p>Returning success on all redundant starting/stopping commands seems better. </p> LU-14689
