用的是惠普dl360服务器，增加了几块磁盘后，发现ubuntu中看不到。
新增6块：
2块保留sata模式
4块组成raid6

Discarding blocks...Done.临时挂载
普通单xfs 磁盘
mount -t xfs /dev/sdc /disk2
raid磁盘
sudo mkfs.xfs /dev/sda
mkfs.xfs: /dev/sda appears to contain a partition table (gpt).
mkfs.xfs: Use the -f option to force overwrite.
这里提示无法挂载，有gpt分区表，因为确认是新raid，我们选择强制格式化，加-f参数:
sudo mkfs.xfs -f /dev/sda
df -h 查看挂载结果
永久挂载
vim /etc/fstab
/swapfile none swap sw 0 0
/dev/sdc /disk2 xfs defaults 0 0
/dev/sdd /disk3 xfs defaults 0 0生效查看:
mount -a
