[Ocfs2-users] invalid opcode bug in dlmglue?

[Brian Kroth]

Excellent.  Thanks for the quick response.

Also, any idea when the tools might support indexed dirs?  I suspect
we'll have some downtime coming up in a couple of months and am
wondering if we can use the opportunity to turn on that feature for
quicker lookup times.

Thanks,
Brian
