几个月前,我们通过添加 VMDK sdi 磁盘来扩展根 XFS 文件系统分区大小(仅为 20G),并将根文件系统增加 +100G
[root@DB_OP_SERVER ~]# pvcreate /dev/sdi
Physical volume "/dev/sdi" successfully created.
[root@DB_OP_SERVER ~]# vgextend VG_DB /dev/sdi
Volume group "VG_DB" successfully extended
[root@DB_OP_SERVER ~]# lvresize --size +100g /dev/mapper/VG_DB-lv_root
Size of logical volume VG_DB/lv_var changed from ....
Logical volume VG_DB/lv_var successfully resized.

现在我们想要将根文件系统增加+50G,以使根文件系统大小达到170G
所以我们更新VMDK磁盘(通过将vSphere客户端中的设置编辑为150G)
再次增加根文件系统需要哪些步骤?
我执行了以下步骤,这样我们就得到了正确的分区大小
首先我们需要重新扫描磁盘
