ubuntu server 試過都唔得
暫時解決唔到
改用 2TB 算數...

    > 2TB single disk 既話你隻碟有無改用 GPT partition format 先？無既話 default MBR 佢應該 address 唔到 2TB 或以上既 space 然後會出事

我試過唔行 raid, 裝單 4T HDD 係無問題喎
上面既圖已經睇晒 setting
我唔覺有地方可以set GPT 喎
請教一下係邊度set?

未解決

甩左 sdb 後reboot都係入 emergency mode
google左成日都無乜成果
有人話 yum update kernel 就得, 我試過都係一樣
入左 emergency mode 開既 file ,插返 sdb 仲係度
仲可以點攪呢
