I work at Monash University. We are using active-standby MDS. We don't yet have it in full production as we need some of the newer Luminous features before we can roll it out more broadly, however we are moving towards letting a subset of users on (just slowly ticking off related work like putting external backup system in-place, writing some janitor scripts to check quota enforcement, and so on). Our HPC folks are quite keen for more as it has proved very useful for shunting a bit of data around between disparate systems.
We're also testing NFS and CIFS gateways, after some initial issues with the CTDB setup that part seems to be working, but now hitting some interesting xattr acl behaviours (e.g. ACL'd dir writable through one gateway node but not another), other colleagues looking at that and poking Red Hat for assistance...
