Dear list, is there a way to see the difference whether I deactivated an OST filesystem-wide by lctl --device 15 conf_param pps-OST000a.osc.active=0 or only locally by lctl set_param osc.pps-OST000a-osc.active=0? And: After deactivation, I see the OSTs still on the device list (as inactive): is there a way to completely remove them, so that new clients would have no idea they ever existed (and the uuids get eventually reused)?

Arne, This is the same question I''ve put two months ago, with no answer. Which kind of installation do you have?

Hi Ramiro, I did the retirement on a test setup, just to familiarize myself with the procedure of draining and retiring/replacing OSSs. The test installation is a 1.8.0.1 Lustre with 40 active and 12 inactive OSTs ;-) Cheers, Arne Ramiro Alba Queipo wrote:> Arne, > > This is the same question I''ve put two months ago, with no answer.
