[Lustre-discuss] OST retirement

[Arne Wiebalck]

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)?

TIA,
  Arne
