[Lustre-discuss] LAST_ID issue on lustre 1.8.7

[Andrus, Brian Contractor]

All,

We seem to be having a bad failure here.
Here is some info from lctl and from looking at the lov_objid for our /work filesystem:

==============================================

What concerns me is that we have 10 OSTs for the filesystem, but there appear to only be 6 showing up in the lov_objid...
Am I reading this correctly? If so how do I recover those 'missing' OSTs.
