Applied new patch and got:
./mdadm -Ss
mdadm: stopped /dev/md127
./mdadm -Asvvv
mdadm: looking for devices for further assembly
mdadm: no RAID superblock on /dev/dm-3
mdadm: /dev/dm-3 has wrong uuid.
want UUID-084b969a:0808f5b8:6c784fb7:62659383
tst=0x10dd010 sb=(nil)
Segmentation fault
Again tried various buffer sizes (segfault above was with char buf[200];)
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) {
char buf[1<<16];
fprintf(stderr, Name ": %s has wrong uuid.\n",
devname);
fprintf(stderr, " want %s\n", __fname_from_uuid(ident->uuid, 0, buf, ':'));
fprintf(stderr, " tst=%p sb=%p\n", tst, tst?tst->sb:NULL);
if (tst) {
fprintf(stderr, " have %s\n", __fname_from_uuid(content->uuid, 0, buf, ':'));
fprintf(stderr, " metadata=%s\n", tst->ss->name);
}
}
goto loop;
}
