Are you mounted with discard ? perhaps fstrim ?




I believe that I have all the default options, and I have one extra partition for images.

At this point I don't have a /var/crash mounted (or a LV even).  I assume I should re-create.


I noticed on another server with the same problem, the var_crash LV isn't available.  Could this be part of the problem?
