• Question1: I am getting AllocateHardByte Failure on the IBP depots while uploading. What should I do? The error may look similar to :

       edu.utk.cs.loci.ibp.IBPException: Allocation failed
       at edu.utk.cs.loci.ibp.ProtocolService.allocate(ProtocolService.java:114)

• Answer: In the past we have seen this problem occur due to a mis-configuration of the IBP depot itself. Usually if the depot is mounted on a directory that does not exist it will give allocation failures. For example: if you have the ibp depot set up (in the ibp.cfg file) to be mounted on /foo. If /foo does not exist...you will see this kind of a failure. The fix is easy. Just match the directory structure.
