Hello, we have a situation where we have a few large VMs that were failing to backup using the vRanger product. at the time, we were on ESXi 4.1 and we had to create a new volume with a 4mb block size or the file would not back up. Now we have upgraded to version 5.0 and purchased a new storage array. the new VMFS volumes are version 5 and now we are getting the exact same error as before. I dont know all the particulars but my backup administrator insists its because the block size is only 1mb on the volume. I cannot find any way to create a new VMFS 5 volume with larger than 1MB. Has anyone else run into this issue?
