I figure that | mixes together metadata and data, since the metadata tells me how much | and from where I read back my data. Sure, they are usually mixed, but some tests emphasize (or stress) file data IO vs. metadata more than others do. And sometimes people ask for a metadata stress test, which would focus on mv, ln, stat, etc., more than reading/writing file data. | I see my semi-private linux_udf@hpesjro.fc.hp.com thread titled "zeroes | read back more often than appended" says a write-read-compare test as | trivial as fopen-fwrite-fclose doesn't yet work. That sounds like a filesystem IO test more than a metadata test, though the problem could be in either area. | I blame that either on my own bonehead newbie errors i.e. illegit test | setup, else low-hanging bugs.
