博客展示了在阿里云进行磁盘扩容的操作过程，包括使用yum install -y cloud-utils-growpart命令安装工具，通过growpart、pvresize、lvresize、resize2fs等命令对磁盘分区、物理卷、逻辑卷进行调整和文件系统的扩容。

[root@doris_be_006 ~]# yum install -y cloud-utils-growpart
[root@doris_be_006 ~]# growpart /dev/vdb 1
CHANGED: partition=1 start=2048 old: size=629143552 end=629145600 new: size=2097149919 end=2097151967
[root@doris_be_006 ~]# pvresize /dev/vdb1
Physical volume "/dev/vdb1" changed
1 physical volume(s) resized or updated / 0 physical volume(s) not resized
[root@doris_be_006 ~]# pvs

/dev/vdb1 vgdata lvm2 a-- <1000.00g 700.00g
[root@doris_be_006 ~]# lvresize -l +100%FREE /dev/mapper/vgdata-lvdata
Size of logical volume vgdata/lvdata changed from <300.00 GiB (76799 extents) to <1000.00 GiB (255999 extents).
Logical volume vgdata/lvdata successfully resized.
[root@doris_be_006 ~]# resize2fs /dev/mapper/vgdata-lvdata
resize2fs 1.42.9 (28-Dec-2013)
Filesystem at /dev/mapper/vgdata-lvdata is mounted on /mnt/data_1; on-line resizing required
old_desc_blocks = 38, new_desc_blocks = 125
The filesystem on /dev/mapper/vgdata-lvdata is now 262142976 blocks long.
