wolverine (128.182.58.80) is configured as a SLASH2 metadata server. Below is a dump of the ZFS configuration:
(pauln@wolverine:zpool)$ sudo ./zpool status

scrub: none requested
config:

To date I’ve been able to successfully run a 10 million file create test (and unlink). Here’s the fio test config:
