Hello, currently, I am using tar to tar and bzip my scientific data into one data packages. However, the data are on multiple NFS volumes. I realized, that tar only reads from one volume, then goes to the next and so on. So first slave1 is the limiting factor, then slave2 and so on, until all the data are taken. I would like to ask, if it would be possible to put a load balancing option in which tar would realize that the data are on different NFS volumes and then starting to load balance the data streams of each device, so that all server would provide equal data streams. It might be even another bonus to provide a bandwithlimit option so that tar would process only a certain maximum data stream per time unit. This would allow to run it in a mild mode without affecting more important jobs.
Please let me know what you think. with best wishes Jens
