Thanks all. This plan no longer sounds as nuts as it did at the start.

We've been running AFS over ZFS over LUKS over EC2/EBS volumes for two years

I realise that sounds like a lot of indirection, but it meets our needs of
flexibility, security and cost.
This approach has also allowed us to incrementally upgrade as needed (replacing
underlying EBS volumes) and, through concurrency, get the throughputs we need.

We deployed a ZFS on Linux server (on Scientific Linux) in the past week.
Pretty simple stuff...the only non-default options are atime=off and
recordsize=64K (which may be wrong, though some posts about ZFS and AFS suggest
it).
About Ceph, we had a test server serving an RBD /vicep partition. And it
worked. We're still building up the Ceph cluster (primarily to provide
OpenStack Cinder volumes) and once it is in production we plan to run a few
virtualized AFS servers with Ceph volumes behind.
All of this is in testing, and though we've not had deal breaking incidents,
the long term stability is still in question.

Out of pure curiosity, does anyone care to share experiences from
running OpenAFS on ZFS?
If any one is running OpenAFS on top of or in a cluster which also uses
Ceph, would you care to share experience, as well as your architecture?
Background: I have 4 Thumpers (SunFire x4500s) with 48tb a pop and am
wondering how best to set up my storage layer. This cluster will both
serve user files and be the backend for a VM cluster.
Thanks,

Volumes shouldn't just show up as corrupt like that, yes.
It now looks like it's a hardware problem with the SAN storage for that
viceb partition. Ouch.
And this is one of the reasons why ZFS is so cool :)
