Planned Failure Volume 计划实施失败量
Primary node data volume failure 主节点数据卷故障
Secondary data volume failure 次要资料磁碟区故障
From a reliability standpoint, RAID-0 has the same characteristics as linear mode — the more drives you add to the array, the higher the probability of volume failure.
从可靠性的立场来看,RAID - 0模式与线性模式具有同样的特征——向阵列中添加的驱动器越多,卷的故障概率就越高。
Actually, if you spread your linear volume over multiple disks, your volume is more likely to become unavailable due to a random hard drive failure.
事实上,如果您的线性卷分布于多个磁盘上,它就很可能由于偶然的硬盘故障而变得不可用。
If you're trying to determine why a server won't boot after a disk failure, the first thing I often do is to un-map or disconnect all disks from the server except for the root volume group.
如果想要判断一个服务器为何在磁盘故障后不能引导,我通常会做的第一件事情是从服务器(根卷组除外),断开所有磁盘的映射和连接。
