Hi All, we are copying large data sets within our lustre filesystem and between lustre and an external nfs server. In both cases the performance is unexpected low and the reason seems that rsync is reading and writing in 32 kB Blocks, whereas our lustre would be more happy with 4 MB Blocks. rsync has an --block-size=SIZE Parameter but this adjusts only the checksum block size (and the maximum is 131072), not the i/o block size. Is there a solution to accelerate rsync?
