[Lustre-discuss] Quota behavior with inactive OSTs

[Kevin Hildebrand]

Hello.  I've just noticed that OSTs marked as 'inactive' for some reason 
don't count in the quota display.

I have a handful of OSTs temporarily marked inactive because they are 
close to full, and as soon as they are marked inactive, 'lfs quota' stops 
showing their contribution to the total.  Is this the correct behavior? 
'lfs quota -v' shows each individual OST properly, but the totals are 
wrong.
I don't actually have quotas set, but I use the quota facility to keep 
track of how much space my users are using, and having the numbers 
inconsistent like this is a pain.

We're running 1.8.7wc with kernel 2.6.18-274.3.1.el5_lustre.g9500ebf.

Thanks,
Kevin
