Dear Craig,

we are running  some OSD-Servers on GPFS.
The OSD-servers are in the production-run sense comparable to
fileservers and 
since GPFS is POSIX-compatible (dont know to how many %), everything is 

However, we run those servers as single-server GPFS. They are server
and client alike.

I don't see any major issues with running AFS on top of GPFS, but ...

- GPFS is more likely to hang as any other network-FS compared to a
  local FS.

- not sure how to deal with the /vicep - naming convention ( can you
  have two /vicepa partitions somehow?) I can check with the
  GPFS-admins here.
