We plan to install a read-only AFS-DB-Server in every school too (makes at least 100). Will Ubik scale to this number of Servers?
Ubik doesn't scale beyond three servers.
Oh. There are (or at least were) cells with 5 Servers around.
And the other question ist: Do the read-only-DB-Servers take part in the election, when they can never become sync-site?
Our idea is, to use different CellServDB-Files in each school containing just the local RO-Servers and the tree Master-RW-Servers. Only the Master Servers will know all other Servers.
Klog seems to select its kaservers randomly from the CellServDB - what about afsd? Is there a "use next"-Server heurestics. What about school-dependend CellServDB-Files, containing just the "local"-RO-DB-Servers and the "master"-RW-Servers?
Nobody in their right mind would use kaserver anyway. Start using Kerberos right away.
Sorry for my bad English. What I wanted to ask is: Does afsd use the same algorithm when it locates a Ubik-Server. In ubikclient.c (which is used by klog too, that's why klog went into this context) is a rather simple randomisation of the CellServ-List. Location of the Servers is not taken into account.
Of course we will use (Heimdahl-)Kerberos 5.
Thank you for your answer.
