Linux磁盘扩容

[MD]

1. 在OCI后台把引导卷从40GB调整为100GB

2.在SSH操作

2.1 lsblk

# lsblk
NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda      8:0    0   40G  0 disk 
├─sda2   8:2    0    8G  0 part [SWAP]
├─sda3   8:3    0 31.5G  0 part /
└─sda1   8:1    0  512M  0 part /boot/efi

可以看到/对应的分区是sda3

2.2 dd 重新扫描磁盘

# dd iflag=direct if=/dev/sda of=/dev/null count=1
# echo "1" | tee /sys/class/block/sda/device/rescan
1

2.3 查询系统类型

# lsblk -f
NAME   FSTYPE LABEL UUID                                 MOUNTPOINT
sda                                                      
├─sda2 swap         c20ab25a-797e-4c88-b9b4-bbc5e279a88c [SWAP]
├─sda3 xfs          e8399f69-1f3e-4713-afca-f2b9c8f7bbc6 /
└─sda1 vfat         9BE4-DC71                            /boot/efi

2.4 安装扩容软件

# yum install cloud-utils-growpart
# yum install xfsprogs

sda3的系统类型为xfs，扩容需要安装xfsprogs

2.5 growpart对应的分区

# growpart /dev/sda 3
CHANGED：partition=1 start=...

2.6 扩展分区

# xfs_growfs  /dev/sda3

2.7 验证

# lsblk
NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda      8:0    0  100G  0 disk 
├─sda2   8:2    0    8G  0 part [SWAP]
├─sda3   8:3    0 91.5G  0 part /
└─sda1   8:1    0  512M  0 part /boot/efi

其他问题：

报错：Couldn’t find valid filesystem superblock.，resize2fs替换为xfs_growfs
报错：Warning: the kernel is still using the old partition table.The new table will be used at the next reboot.，运行partprobe重新读取分区表
