This bug seems to only occur after LU-2547, not sure if this is related.

Comment by Nathaniel Clark [ 23/Apr/13 ]

This seems to be due to dd being slow. Test has minimum dd speed of 2MB/s to "pass" stage 1.

https://maloo.whamcloud.com/test_sets/7388d67c-ac07-11e2-ba3e-52540035b04c
Has 1.1MB/s

ldiskfs seems to run in the 10 to 16 MB/s range, where zfs seems to run in the 1 to 6 range.
