Got it: while "roaming", the soft RAID partition metadata appears to have been
overwritten.
Specifically, BIOC_SCBOOTABLE is unset, as shown in /softraid_amd64.c in
srprobe():
if (bv->sbv_state != BIOC_SVOFFLINE)
printf(" sr%d%s", bv->sbv_unit,
bv->sbv_flags & BIOC_SCBOOTABLE ? "*" : "");
which appears to be called from efiboot.c.
When I boot, offered are:
disk: hd0 hd1 sr0* sr1
meaning that sr1 has lost the bootable flag.
Now: how do i set this flag on that RAID partition on the external disk?
Bioctl is not able to set it.
Any ideas?
