現(xiàn)在服務(wù)器的硬盤都比較大，經(jīng)常會超過2TB。所以安裝系統(tǒng)的時候經(jīng)常會出現(xiàn)一些新的問題。
1，安裝windows server 2008r2/2012r2時提示：無法在此驅(qū)動器上安裝windows。
因為服務(wù)器出廠一般默認(rèn)還是BIOS引導(dǎo)，當(dāng)你合并VD（虛擬磁盤）后，改用UEFI引導(dǎo)安裝windows時會出現(xiàn)此錯誤。此時你可以使用”shift+F10”快捷鍵打開命令行窗口。執(zhí)行以下命令清除之前BIOS引導(dǎo)時磁盤分區(qū)殘留的信息。命令如下：
diskpart （啟動diskpart程序）
list disk （列出現(xiàn)有的磁盤，一般合并后為一個disk0）
select disk 0（這里根據(jù)實際情況選擇你要清除殘留信息的磁盤）
clean （清除所選磁盤殘留信息，注意所有的數(shù)據(jù)也將丟失）
然后就可以像平時安裝windows那樣進(jìn)行安裝了。
2，超過2TB的硬盤不能劃分為一個分區(qū)。
這是因為BIOS引導(dǎo)下默認(rèn)MBR分區(qū)格式最大只能支持到2.1TB，超過了就不能劃分為一個分區(qū)。需要更改為UEFI格式引導(dǎo)，采用GPT分區(qū)格式。
3，GPT分區(qū)格式磁盤不能建立擴(kuò)展分區(qū)，不能建立邏輯分區(qū)。
這是因為GPT分區(qū)本身不支持?jǐn)U展分區(qū)和邏輯分區(qū)。但GPT分區(qū)格式windows下支持最多128個主分區(qū)肯定是夠用了。所以直接分區(qū)主分區(qū)就好了。
