When my rsync from a different system to one of the NFS mounts runs, I get like 48G of Inactive memory that goes back to free if I umount the share. I'm wondering why this memory moves from ZFS ARC to INACT. And, is this expected? -- Larry Rosenman http://www.lerctr.org/~ler Phone: +1 214-642-9640 E-Mail: ler@lerctr.org US Mail: 108 Turvey Cove, Hutto, TX 78634-5688
