Phil:
I did add the Distribution context to my pvfs2-fs.conf , and restarted
the server nodes, and received an "Option cant be defined in that
context" error.
The error points to the Filesystem context, maybe indicating that I
cannot declare the distribution sub-context here (?)
I have attached the error and a copy of my pvfs2-fs.conf
The error comes up when I create a storage space.
[I have 4 storage servers and 1 MDS. I tried by reconfiguring storage
and restarting the servers and the error persists. It also says that the
host names must be consistent [see log] . Thats strange since otherwise,
the servers start fine, without the Distribution context defined]
