I've never checked -CURRENT, just thought of whether ZFS can do this or not. Let's assume there's a shared disk on a scsi bus, that's attached to two boxes. Can that disk be used simultaneously with ZFS on the two boxes at the same time? AFAIK UFS2 is unable to do this, since it doesn't have any on-disk synchronization and similar features, that would enable an operation like this. Sincerely, Gergely Czuczy mailto: gergely.czuczy@harmless.hu --=20 Weenies test. Geniuses solve problems that arise. --MGYHOYXEY6WxJCY8 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) owFFU7FuE0EQNYmQ0EoUaZDoRjQp4jvsKDbBKAqRiUOUiCJOQAIJtHc39i252zU7 s3bsjo6CAlEgJIqID0BKEagQRZp0UOQH+ACoqOjYs2PS7c6+ee/N2903V2dLM3Pf j46fLLx+++HSp5m/0ULumHU3yKXtKx1UK5VqULtdqdeCpeBWZ6lSrS0ltXq9jnEU tY5GJ02jGTUHu8MeNoDxgG/2Mqn0HYhTaQl5xXEnWBZT3D1FPUOKldENUDpTGv+f 7VqpqYM2WNexSZTuNuCFM4xJ0LNKs4wyFOI+ZpkRYnO+j0CIGnKph14M431M4HGr 7VkhaO7t7Kw/2C2D1AmMsV3DQno+pEIbZGQcT+EdixhREk6QGvtop4ziguq5IwZO jeumDKYDgxQ59ciCJJYaEuNPFYGxoA2HQmwjzxNIIpcjFFAstkA+GG81UbQPhROg mBREjsoeJH2LkMzS6yfAnnJgIDIHSCE0vUiBmLRGCI48hlTuMpYajaNsKAaK07El U4Dxoh8kjwskCzcqx1VYa61tbsFeq70ovG+ni4QLzfNJyp5bxwjKKxokPc+QSh9Q EbjRQeFC0FDHqTVajeQkVz12pDJpoYOSncXzuWBgXJYAjlWEH8X00E6aMrWPY0Uf WruQtJgNy0JsoO36FTRHLh4NRS5VxqYB3Uk5jMfluz7OPEOiMHVCBMHKYkU88g9D +ZHZ33YIG37joyIgk3n7PWu8g5wmrqRVhKF4tTp7uVQ86OlvmJt5xqXD/Ovpz5fv 5J+HPz5/OWu1r/erv66UDp+e1s62r73/9jEOh/3jkxvLza3f/wA= =Apir -----END PGP SIGNATURE----- --MGYHOYXEY6WxJCY8--
