xfs 分区

要使用 xfs 文件系统，先分区，后格式化

安装 xfs 套件

yum install xfsprogs

通过 fdisk 或 parted 进行分区

parted /dev/vdb
(parted) print                                                            
Error: /dev/vdb: unrecognised disk label
Model: Virtio Block Device (virtblk)                                      
Disk /dev/vdb: 1563GB
Sector size (logical/physical): 512B/512B
Partition Table: unknown
Disk Flags: 

parted /dev/vdb
mklabel gpt
mkpart primary xfs 0% 100%
print
quit

自动脚本 auto_parted.sh

parted /dev/vdb << EOF
mklabel gpt
mkpart primary xfs 0% 100%
print
quit
EOF

格式化为 xfs

[root@localhost ~]# mkfs.xfs /dev/xvdb1
meta-data=/dev/xvdb1 isize=256 agcount=4, agsize=7864318 blks
= sectsz=512 attr=2, projid32bit=0

mkfs.xfs

自动生成 fstab

uuid=$(blkid -s UUID -o value /dev/sdb1)
echo "UUID=$uuid /data                   xfs     defaults        0 0" >> /etc/fstab
