One of our (3) AFS servers has a mounted read-write volume which must be available 24x7 to our batch system. The server is as resilient is we can make it, but still it may fail outside normal working hours for some reason. For technical reasons related to the software installed on the volume it is not possible to use read-only volumes mounted from our other servers (the software must be installed and served from the same directory name), so I have devised the following plan in the event of a failure:
a) create read-only volumes on the other 2 servers, but do not mount them; use "vos release" whenever the software is updated b) in the event of a failure of server1 (which has the rw volume), drop the existing mount and mount one of the read-only volumes (we can live with the read-only copy whilst server1 is being repaired/replaced) in its place. Can anyone see problems with that scenario ? We could use "vos convertROtoRW"; how would that affect the process ?
