Note that I think this dmesg stuff overlaps with the last lot, namely the start of this is the tail end of the array starting successfully last time. I'm using ./mdadm, so that's the version I downloaded from Neil's repository yesterday ... I'll investigate the source when I get the chance (wives!!! :-) So is this virtualbox and fuse playing up? Dunno ... (this vm is mono-processor - shouldn't make any difference ...)
