So we do only map up cells in /afs which have a valid AFSDB-rr in DNS, this is an at least 10 year old standard. So if you choose an cellname where you will not be able to add an AFSDB-rr in DNS lets say "idontlikedots", we will never map your cell in our /afs which prevent our users from accessing your cell. So if you ever want to add AFSDB-rr in DNS ,which i recommend, i would pick a cellname that in "in" your domain. /Jimmy ___ OpenAFS-info mailing list [EMAIL PROTECTED] https://lists.openafs.org/mailman/listinfo/openafs-info

There are at least 250 active and public AFS-cells on the internet. Thats what my afscrawler found out a year ago. And there were about 60.000 AFS-clients. The biggest site was cern.ch in clients and data ammount. I have asked all 60.000 clients what version they were running, we presented that results on The AFS Workshop Dec 2002 in Monterrey.

Re: [OpenAFS] slave volumes
"klaas hagemann" <[EMAIL PROTECTED]> writes: > as far as i understood afs, i can create severeal read-only replicas of a > volume. How is the decision made, which of these replicas is taken? In the case of openafs/transarc: Your client will pick one of the sites by random, sites with a lower "serverpref" are more likely to be selected. the serverpref is today calculated by pingtime and giving some bonus if your are located on the same Class-C network. Your client may keep accessing this replica untill it goes away. (at least true for Transarc) In the case of arla: serverpref will be calculated by ping time and nothing else. The client will look at "serverpref" for EACH AFS-operation. Which gives true loadbalancing for sites with almost equal pingtimes. > We have a distributes WAN and want to avoid that the Client takes a volume > which is behind a very thin connection. For availability reasons all the > replicas should stay available but in an ideal situation only the volume > with the widest or fastest connection should be taken first. Has the faster connection also better pingtime ? In this case youre lucky. If the wider connection has better pingtime than the narrow one, it will suck. > Can someone explain me the algorithm used by OpenAFS? There is no general algorithm, algorithm may be slighly different dependent on the version you are using. Arla 0.36 (or at least 0.37) will be using an completly different and more adaptive algorithm. /Jimmy ___ OpenAFS-info mailing list [EMAIL PROTECTED] https://lists.openafs.org/mailman/listinfo/openafs-info

The server should/might be compatible with Tru64 5.1, however i do recommend to compile your own version. The client is NOT compatible with 5.1 or 5.1a! For the client you have to use the arla-client instead, the openafs-client does not work at all. However i have never tested running an arla-client on the same mchine as an openafs-server, but it should work.

Do not ever write your logfiles into direct to AFS. The data will not be written untill you do fsync() or close(), depending on clientimplementation.
