我的磁盘阵列有多大？

我的 SunOS 5.10 主机上有 3 个 Sun 6140 磁盘阵列，我想知道磁盘容量。

根据zpool list我是否有 5TB 和 16TB 的池。format只显示 12 个磁盘

奇怪的是，format声称磁盘大于 1TB，但根据6140 数据表。

/etc/hosts包含

#6140 Disk array
10.0.68.65
10.0.68.66
10.0.68.67
10.0.68.68

所有内容都可以 ping 通。

我没有看到任何 RAIDzpool status

问题

由于每台 6140 都有 16 个磁盘，我预计会看到 3x16 个磁盘，但我只看到 12 个磁盘，其容量比数据表允许的要大，而且我没有看到任何配置的 raid。而且报告的磁盘大小为什么会因磁盘而异？

如何找到磁盘的实际容量？

答案1

您期望的是 JBOD，但看起来它可能被设置为 SAN，并且您看到的是 LUN。您应该检查 6140 本身。

答案2

如果你认为操作系统在欺骗你，你可以运行这个

zfs list

它将向您显示 ZFS 在这些磁盘上有多少可用空间。
