Someone here already mentioned variable stripe sizes. ZFS doesn't just add a checksum sector after each block (something i've been planning to write an md module for, for a couple years). It writes the checksum at the end of the tree member, inode, dirent, whatever. So there's no read-modify-write when you write < 1 checksum block size. One thing i noticed about zfs that surprised me: it's using indirect blocks, from what i saw. -- Tom Vier <tmv@comcast.net> DSA Key ID 0x15741ECE - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
