The arrays are clearly currently assembled. Trying to assemble them again is not likely to produce a good result :-) I should have said to "./mdadm -Ss" first. Could you apply this patch and then test again with: ./mdadm -Ss ./mdadm -Asvvv Thanks, NeilBrown diff --git a/Assemble.c b/Assemble.c index afd4e60..11323fa 100644 --- a/Assemble.c +++ b/Assemble.c @@ -344,9 +344,14 @@ int Assemble(struct supertype *st, char *mddev, if (ident->uuid_set && (!update || strcmp(update, "uuid")!= 0) && (!tst || !tst->sb || same_uuid(content->uuid, ident->uuid, tst->ss->swapuuid)==0)) { - if (report_missmatch) + if (report_missmatch) { + char buf[200]; fprintf(stderr, Name ": %s has wrong uuid.\n", devname); + fprintf(stderr, " want %s\n", __fname_from_uuid(ident->uuid, 0, buf, ':')); + fprintf(stderr, " have %s\n", __fname_from_uuid(content->uuid, 0, buf, ':')); + fprintf(stderr, " metadata=%s\n", tst->ss->name); + } goto loop; } if (ident->name[0] && (!update || strcmp(update, "name")!= 0) && -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
