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

[Kurt Strosahl]

Thanks,

   At first I was a bit concerned that the ost wasn't set to read only, but after I observed it for a bit I realized that it was just not being reported as read only.  I agree that it is quite annoying... as, under lustre 1.8 I had the mds occasionally set osts to read only (discovered by using the lctl command).

cat /proc/fs/lustre/lov/*/target_obd
<other osts>
12: lustre2-OST000c_UUID INACTIVE
13: lustre2-OST000d_UUID INACTIVE
14: lustre2-OST000e_UUID INACTIVE
