> GEOM_MIRROR: Cannot add disk zvol/tank0/vol0 to mirror0 (error=45).
seems to be triggered by the following code in sys/geom/mirror/g_mirror.c:
error = g_getattr("GEOM::candelete", disk->d_consumer, &i);
if (error != 0)
goto fail;
plus the fact that ZFS zvol does the following:
case BIO_GETATTR:
case BIO_DELETE:
default:
g_io_deliver(bp, EOPNOTSUPP);
break;
Perhaps, the gmirror code should be more flexible with respect to EOPNOTSUPP
from g_getattr?
