It cannot be achived in the same manner afaik. If you have some files that shall be distributed 3 times, some 5 times and others just 1 time, the configuration will become extremely complex and as far as I know it is also not possible to let glusterfs chose random nodes for storage, e.g. you have to manually define the nodes where a "3 times" file will be stored etc.. If there already is a way to achive this randomly, I would be very happy to know. If not, take my immaginary balance translater as a feature wish :) > Lets fix the problem of selfheal you faced when you started this thread, > is it still valid? Yes it is. When I started this thread, I were using server side AFR to replicate two datastorages and two namespaces each. Then I used unify on the AFRed ds and ns, also serverside. I did not find a way to get this basic setup working as expected (see the detailed description earlier in this thread). In the underlying export directories there were also some files with a timestamp of 1970-01-01 created (replicated copies created by AFR?). In the meantime I decided to swtich to clientside AFR without a namespace (as provided by unify). Self-Healing basically works this way as expected but I also see some files being 1970-01-01ed in the underlying export directories. Let's say I create a file on Server A, it will be replicated to Server B with a timestamp of "0". However, it will show up with the correct timestamp in glusterfs mounts as long as there is one copy in the cluster with the real timestamp. The problem is, if first Server A crashes and later Server B, the timestamp will be incorrect also in mounted directories until the file is touched again. When it is touched, the timestamp is corrected on both nodes, so it seems that the incorrect timestamp only is set on creation, not on update. I am using Debian Etch with GlusterFS 1.3.9 on ext3. Both servers are correctly synchronized. regards Daniel
