A hundred megabytes (plus one) of zeroes should be d748d1b68b9dc69c4717ebc070dbc547d129bcc6. So that is the root of your problem (the empty file will obviously not trigger the "too large" fsck check), but I don't know why it would be failing. Maybe check the output of "test-tool genzeros 104857601" to make sure that it as expected? If not, then the bug is somewhere in t/helper/test-genzeros.c. It's on the left-hand side of pipe. Maybe it is getting a write() error, but we are ignoring it? Maybe a patch like this would help diagnose: diff --git a/t/helper/test-genzeros.c b/t/helper/test-genzeros.c index 8ca988d621..0574917005 100644 --- a/t/helper/test-genzeros.c +++ b/t/helper/test-genzeros.c @@ -18,14 +18,14 @@ int cmd__genzeros(int argc, const char **argv) /* Writing out individual NUL bytes is slow... */ while (count < 0) if (write(1, zeros, ARRAY_SIZE(zeros)) < 0) - return -1; + die_errno("write()"); while (count > 0) { n = write(1, zeros, count < ARRAY_SIZE(zeros) ? count : ARRAY_SIZE(zeros)); if (n < 0) - return -1; + die_errno("write()"); count -= n; } -Peff
