I've been trying to get replication to work all day and I think I've identified some issues and sharpened my questions. First, suppose I have a realms file like this: realm1 coda1 coda2 realm2 coda2 where coda1 is the scm and coda2 is (supposedly) replicating it. If I add a file to realm1 and then go to realm2 to see if it has appeared, I get timeout and permission denied errors. A `cfs lv` tells me I'm disconnected from realm2 and no amount of `cfs reconnect` fixes that. By the way, realm2 doesn't have to be defined, going to /coda/x.x.x.x has the same effect when x.x.x.x is the ip of coda2. At this point, restarting the client results in an error. To get venus to start again I have to touch /usr/coda/venus.cache/INIT. So at this point, I seem to have a replicating server. However, I have a question. I spent much of the day not realizing the problem stated above so I was trying to create volumes on the replicated server. After analyzing createvol_rep I came up with this command: volutil -h coda2 create_rep /vicepa /.1 2130706432 where that last number is the decimal representation of the hex number found in the gruopid column of the / partition on the scm (as shown in the VRList file). I did this because it looks like createvol_rep will create volumes on multiple servers using that command, but won't let you add volumes on other servers if they come later. The question: what is the point of creating volumes on the replicated server when it appears that volumes I didn't use volutil to create can be seen on that server anyway? Or did creating the "/" partition trigger everything to work? (I'll find the answer to that last part myself soon as I wipe clean the replicating server and try again from scratch). ..Patrick On Thu, 2005-04-07 at 08:54 -0600, Patrick Walsh wrote: > I need some help setting up a non-scm server.
