Hi! What would be the recommended settings for an xrootd installation
that use a distributed file system like gluster?
beside the dfs what other tweaks will make sure that the load is equally
distributed among the file servers?
it would seem that the redirector remembers the last data server that
answered a file query so the same server is used again ...how can this
be disabled?
also, given the uniformity of the storage space, is there a need for a
redirector?(or cmsd)? could a simple xrootd (and with dns aliasing)
distribute the load equally?
also, for really large installations (and not only) i seen that there is
a mechanism for keeping a metadata cache of all namespace(s) - XrdCnsd
can this be used to bypass the metadata query of files and reduce the
load of the actual block device?
also, i seen the in the documentation the XrdCnsd is started by xrootd,
which i do not think is a safe model (service started by a service)
is there a way for ofs.notify to send the information to an already
started service?
Also, this inventory is a collection of what? in the data servers the
namespace is a collection of symlinks
Thank you!
Adrian
