Sure. > I need to know whether rdist was reading HAMMER via NFS or writing to > HAMMER via NFS, and what kinds of file structure was being copied? > (big files, little files, hundreds of files, thousands of files.. what?). Just an rsync -av src dst, where dst is the nfs-mounted hammer volume, which was just created, so I don't think rsync could read much. It got stuck in the devel/ directory (in an old dragonfly sys/ checkout even). The file was some version of ibcs2_stat.c. Before getting there it had copied over a few hundread thousands of files, some small, some average-sized. I'm going to make sure I can get a dump and then try it with latest head. Aggelos
