Any idea why Glibc's posix_fallocate makes any difference? Doesn't it simply write a lot of zeros? In that case, why doesn't rsync writing lots of data sequentially result in the same number of extents? -- Jamie -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
