Neil, Here's a couple patches that are necessary for MD before I can add RAID10 to the list of supported personalities through dm-raid.c: 1) md-raid10-rename-mirror_info.patch 2) md-raid1-rename-mirror_info.patch 3) md-move-IO_BLOCKED-to-md_h.patch 4) md-export-md_raid10_congested.patch I'll send the patch that enables raid10 as a separate patch that depends on this patch set and a couple of DM patches. brassow -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
