Scott's view (which sounds good to me) is that GEOM should include a library of routines for working with common transforms such as RAID1, striping, etc. Each ATA RAID vendor format would then consist of a small GEOM module that used the library routines to manage all the I/O and the bulk of the module would be managing a specific metadata format. -- John Baldwin _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
