rbd 磁盘扩容resize 容量过程(当系统盘无法在运行状态下扩容时)

admin · 发表于 2025-2-10 10:10:44

执行扩容：
[root@controller1 src]# rbd resize --size 50G hdd-8T-volumes/volume-7339c495-25dd-44a3-b0cb-3b00cd59e070
Resizing image: 100% complete...done.
[root@controller1 src]# rbd info hdd-8T-volumes/volume-7339c495-25dd-44a3-b0cb-3b00cd59e070

在openstack上因为更新底层不一定能正常更新磁盘空间，可以调整磁盘大小，还需要修改cinder的数据库。
