Re: [Lustre-discuss] OST retirement
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.

[Lustre-discuss] OST retirement
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)?
