[Gluster-users] Ubuntu upgrade broke Gluster

[Brantley Hobbs]

All,

I have 2 Ubuntu 13.10 nodes (gluster 3.2.7) with local gluster volumes set to mirror (two webservers keeping their content in sync with one another).  I upgraded one node to 14.04.1 (gluster 3.4.2).  After rebooting, Gluster can't find my volumes.  "gluster volume status" returns "No volumes present".

The following output is present in my gluster logs:
-----------------------------------snip----------------------------------------
W [rdma.c:4197:__gf_rdma_ctx_create] 0-rpc-transport/rdma: rdma_cm event channel creation failed (No such device)
E [rdma.c:4485:init] 0-rdma.management: Failed to initialize IB Device

-----------------------------------snip----------------------------------------

Does any of this ring a bell with anyone?  Am I providing enough information?

Sorry for what is probably a set of n00b questions, but I'm having trouble finding a solution here.  I'd appreciate any pointers.
