Here are three patches for md in 2.6.13-mm1 The first (embarassment) gets sb_size initialisation REALLY right. I did more testing with mdadm-v1 and found hot-add wasn't working either. This patch definitely covers all cases. The other two fix problems with raid10 when enough drives fails that not all block are available. It was particularly a problem as recovery would BUG-out, but other issues are fixed to. These patches are tested and suitable for early release to Linus. Thanks, NeilBrown [PATCH md 001 of 3] Really get sb_size setting right in all cases. [PATCH md 002 of 3] Fix raid10 assembly when too many devices are missing.
