Hi, > write(4, > "bitm\4\0\0\0~\332I'%L\33n\363\303\24J\237AY\322\267\252J\0\0\0\0\0"..., > 2560) = -1 EINVAL (Invalid argument) This mdadm version has a problem of opening the device with O_DIRECT, but then using an unaligned buffer for write(). Your strace doesn't contain the open() command for fd=4, so please look earlier in your strace to confirm the O_DIRECT part. Also, confirm that this write that returns EINVAL uses an unaligned buffer. Once you confirmed these, grab mdadm 3.2.4 or the following commit: 6ef8905 super1: make aread/awrite always use an aligned buffer.
