As far as I remeber, there was some support for "splicing" GEOM I/O schedulers into "live" GEOM graph without rebuilding graph from scratches. Is it possible now for GEOM class, which is completely transparent (like geom_nop, without offsets, errors, etc) to be inserted into live GEOM graph? I need to put one such GEOM between device and file system and I don't want to stop server, unmount filesystem, etc... --=20 // Black Lion AKA Lev Serebryakov
