Hi folks-that-dwells-among-multiple-replicated-servers,   The doc refers to two bad URLs on this page : https://glusterdocs.readthedocs.io/en/latest/Administrator%20Guide/RDMA%20Transport/ Section : Setup The first one isn't anymore in any DNS server : site not found : http://pkg-ofed.alioth.debian.org/howto/infiniband-howto.html The second one drives you to the site but not its page : http://people.redhat.com/dledford/infiniband_get_started.html NB : This page apparently do not exist anymore.   There is also a link that points to either a 404 or a private page in this page : https://glusterdocs.readthedocs.io/en/latest/Administrator%20Guide/Gluster%20On%20ZFS/ Section : Recurring ZFS Snapshots Link name : Recurring ZFS Snapshots Pointing to : http://community.spiceworks.com/how_to/show/15303-recurring-zfs-snapshots Leads to a page that says : Oops! That page doesn’t exist or is private.   Jean-Yves
