--Z95B/7ub16XurzO8 Content-Type: text/plain; charset=iso-8859-2 Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hello hackers... I've spend some time working on GEOM Gate, so... Cache was implemented, but only for reading (cache for write requests isn't good idea here, IMHO). Many workers can be used now. This will help to split requests. Requests are queued and always worker with minimal number of pending requests is choosen. Workers can be added at run-time with '-r' option. ggd(8) use now NFS-like exports file. Sample entries: 192.168.0.3 RD /dev/acd0 192.168.0.4 RW /test.img 192.168.0.5 RW /dev/ad0s1a I've also wrote some manual pages: - gg(4), - geom_gate(4) (exists, but isn't finished yet), - ggc(8), - ggd(8). There are few sysctls that could help in performace and memory consumption tuning and more to come. TODO. Errors handling needs more work. Maybe UDP (for now transport is done via TCP). Per-device sysctls created automatically. Regression tests. Performance benchmarks. GEOM Gate is avaliable at: http://garage.freebsd.pl/geom_gate.tbz http://garage.freebsd.pl/geom_gate.README See you all at BSDCon 2003!:) --=20 Pawel Jakub Dawidek pawel@dawidek.net UNIX Systems Programmer/Administrator http://garage.freebsd.pl Am I Evil?
