为什么我的 WD blue 4tb 磁盘在 gparted、gdisk、parted 和 fdisk 中显示为 2tb

  • 772

它们使用双 sas raid 卡连接。目标是使用 mdadm 创建一个用于 nas 目的的大型 raid 6 阵列和一个 plex 服务器。但如果我似乎无法格式化 4tb，我不会尝试创建一个巨大的 24tb 数组。

nasplex@nasplex-pc:~$ sudo gdisk /dev/sdc
GPT fdisk (gdisk) version 1.0.4

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

Command (? for help): ^C
nasplex@nasplex-pc:~$ sudo parted /dev/sdc
GNU Parted 3.2

    因为我用的是旧的raid卡。一个 lsi sas 3801E，它只支持最多 2tb 磁盘。请参阅：Broadcom.com/support/knowledgebase/1211161495837/using-drives-2tb-in-capacity-with-lsi-sas-hbas
