I've added:
diff --git a/Manage.c b/Manage.c
index 919dc01..a203ec9 100644
--- a/Manage.c
+++ b/Manage.c
@@ -87,6 +87,8 @@ int Manage_ro(char *devname, int fd, int readonly)
if (*cp)
*cp = 0;
ping_monitor(vers+10);
+ if (mdi->array.level <= 0)
+ sysfs_set_str(mdi, NULL, "array_state", "active");
}
return 0;
}
so that you can set raid0 to --readonly again. Yell if you think that is
wrong.
