lvconvert 创建缓存的 LV - 导致设备映射器：重新加载 ioctl (254:0) 失败：参数无效

Question

在 Sles15 上，成功创建 Meta 和 Cache LV 并将它们与 结合后lvconvert，我将 Cachepool 与慢速 LV 关联起来，并收到以下错误：

lvconvert --type cache --cachepool vgVMs9/VMs9Cache vgVMs9/VMs9
您是否要清除缓存池 vgVMs9/VMs9Cache 的现有元数据？[y/n]: y

设备映射器：重新加载 ioctl（254:0）失败：参数无效
无法锁定逻辑卷 vgVMs9/VMs9。

我已经在另一个相同的 SLES15 系统上以完全相同的方式成功完成了此操作

http://fibrevillage.com/storage/460-how-to-create-lvm-cache-logical-volume

故障系统已经删除和添加了许多 LV 和 VG，因此我怀疑 LV 元数据存在问题，但我无法发现问题在哪里。

在重新创建 vg 或 lv 之前，我查看了以下内容，一切看起来都很好。我甚至销毁了物理阵列并将其重新创建到不同的 sd。

当我尝试为其他两个 LV 创建缓存时，也遇到了同样的错误。

如果对下一步行动有任何帮助，我们将非常感激。

这是使用不同的 raid 阵列和 SSD 进行的另一次尝试的 strace
