[lustre-discuss] lustre2 cannot set ost to read only

[Kurt Strosahl]

Hello,

   I've been following the procedure for setting a lustre ost to read only, but it doesn't seem to be working.

I want to set this ost to read only (as seen on the mds):

> lctl dl | grep OST000e
 23 UP osp lustre2-OST000e-osc-MDT0000 lustre2-MDT0000-mdtlov_UUID 5

> lctl --device 23 deactivate

> lctl dl | grep OST000e
 23 UP osp lustre2-OST000e-osc-MDT0000 lustre2-MDT0000-mdtlov_UUID 

Looking in dmesg I see the following:
Lustre: setting import lustre2-OST000e_UUID INACTIVE by administrator request

And the same thing shows up in messages:
kernel: Lustre: setting import lustre2-OST000e_UUID INACTIVE by administrator request

I'm running lustre 2.5.3 on Centos 6.5:
lustre-2.5.3-2.6.32_431.23.3.el6_lustre.x86_64.x86_64
kernel-2.6.32-431.23.3.el6_lustre.x86_64
