Hi, after updating to mdadm 3.2.2 (by way of upgrading from Fedora 14 to 15) from 3.1.5 I am no longer able to boot my IMSM raid, which I was able to for the last 5 years or so. The errors I am getting are: mdadm(IMSM): Unsupported attributes : 40000000 mdadm: IMSM metadata loading not allowed due to attributes incompatibility. I tracked that down to the patch at http://www.spinics.net/lists/raid/msg34783.html According to that patch 40000000 means #define MPB_ATTRIB_NEVER_USE __cpu_to_le32(0x40000000). Any advice why an unused but aparently set attribute should stop the raid to boot? For now I am up and running with 3.1.5 but would like to keep up with the latest mdadm if possible.
