The EOS FST server can be configured to store data on any (shared) filesystem as storage device which supports extended attributes. To avoid that filesystems sharing a device or a shared filesystem are accounted multiple times in the space and node aggregation, one can label each filesystem with a shared filesystem name to indicated that all devices using this name share the same hardware resource.
The shared filesystem name can be configured when a filesystem is added e.g. a CephFS filesystem names cephfs1
fs add 7a41781f-62dc-4f18-8f64-375e57487578 foo.cern.ch /cephfs/ default rw cephfs1
If filesystems are already registered or the filesystem name has changed one can use the filesystem config command:
fs config 1 sharedfs=cephfs1
