扩展的raid 5没有扩展

Question

我在 dl360p gen8 HP 服务器中有一个带有 25 个 1Tb 磁盘和 P421 raid 卡的 D2700。

它被突袭为两个突袭5，每个突袭2个备用。我决定将其中的一个raid 5 删除，删除一个raid 并将磁盘添加到另一个raid。

现在几周后用 hpssacli（对我来说是新的）查看它们看起来很好，所有 25 个磁盘都显示正常，raid 显示正常，但我仍然只有 11.8 TB，它应该显示大约 23 TB ..？

这就是“sudo hpssacli ctrl all show config”给我的：

这有点疯狂......对于RAID5来说，磁盘太多了。您有两个热备用驱动器这一事实抵消了这一点，但是该死！！

但是，您已经扩展了底层阵列，但尚未扩展逻辑驱动器。请记住，“阵列”是磁盘的物理分组。“逻辑驱动器”是您分配 RAID 级别的对象。一个阵列中可以有多个逻辑驱动器。

阵列 A（SAS，未使用空间：8974754 MB）

这是您未使用的空间，因此您可以从可用空间中创建另一个逻辑驱动器，或扩展logicaldrive 1.

ctrl slot=1 ld 1 modify size=? 或者 ctrl slot=1 ld 1 modify size=max

<target> modify [size=#|min|max|maxmbr|?] [forced]
   Extends the logical drive to the specified size. The implied units are MB.
   max will extend the logical drive to its maximum size. maxmbr will extend to
   the maximum size the master partition table allows. The target can be any
   valid logical drive.
