Before this checkin, vol_id was only called for partitioned devices and

Probably vol_id needs to use O_NONBLOCK when opening sr devices. Does
that fix it?
Yes, indeed using a patch like this:
diff --git a/extras/volume_id/vol_id.c b/extras/volume_id/vol_id.c
index 5c4e05d..3dc9f95 100644
--- a/extras/volume_id/vol_id.c
+++ b/extras/volume_id/vol_id.c
@@ -224,7 +224,7 @@ int main(int argc, char *argv[])
goto exit;
}
- fd = open(node, O_RDONLY);
+ fd = open(node, O_RDONLY | O_NONBLOCK);
if (fd < 0) {
fprintf(stderr, "%s: error opening volume\n", node);
rc = 2;
fixes the problem, too. But it looks like that this is discouraged:
