I think that the array for nested raid levels, in metadata.c, may be upside down. When I build a raid0+1 with Intel or Nvidia (one mirror array of two stripe arrays), it is reported as a "raid10" with [dmraid -s], this should be "raid01". If I reverse the nesting to raid10, in Intel (one stripe array of two mirror arrays), it is reported as a "raid01" with [dmraid -s], this should be "raid10". Can we just reverse the array in metadata.c? From: static const char *stacked_ascii_type[][5] = { { "raid10", "raid30", "raid40", "raid50", "raid60" }, { "raid01", "raid03", "raid04", "raid05", "raid06" }, }; To: static const char *stacked_ascii_type[][5] = { { "raid01", "raid03", "raid04", "raid05", "raid06" }, { "raid10", "raid30", "raid40", "raid50", "raid60" }, }; Thanks, Jason _______________________________________________ Ataraid-list mailing list Ataraid-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ataraid-list
