我的磁碟陣列有多大？

我的 SunOS 5.10 主機上有 3 個 Sun 6140 磁碟陣列，我想知道磁碟容量。

根據zpool list我有一個 5TB 和 16TB 的池。format只顯示 12 個磁碟

這里奇怪的是format聲稱磁碟大於 1TB，根據6140 數據表，情況並非如此。

/etc/hosts包含

#6140 Disk array
10.0.68.65
10.0.68.66
10.0.68.67
10.0.68.68

所有都可以ping通的地方。

我沒有看到任何 RAIDzpool status

問題

由於每個 6140 有 16 個磁碟，我希望看到 3x16 個磁碟，但我只看到 12 個比數據表允許的更大容量，而且我沒有看到任何配置的 RAID。報告的磁碟大小因磁碟而異嗎？

如何找到磁碟的實際容量？

您期待的是 JBOD，但似乎這可能設置為 SAN，並且您看到的是 LUN。您應該自己檢查 6140。

如果你認為作業系統在騙你，你可以執行這個

zfs list

它將顯示 ZFS 從這些磁碟中有多少可用空間。
