篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了bad geometry: block count 65536 exceeds size of device (53248 blocks)相关的知识,希望对你有一定的参考价值。
在虚拟机里做LVM的缩减的时候,未卸载逻辑卷的情况下进行了缩减导致报错:
bad geometry: block count 65536 exceeds size of device (53248 blocks)
猜测大概的意思就是我分区表里是64M(PE为4M),而实际逻辑卷已被缩减到52M。
参考了几篇文章也没解决掉:
我就尝试直接去扩展逻辑卷,结果就好了。
逻辑卷扩展的步骤: 1.先确保扩展的大小;并确保所属的卷组有足够的剩余空间 2、扩展物理边界 lvextend -L [+]size /path/to/lv_device 3、扩展逻辑边界 resize2fs /path/to/lv_devive 缩减逻辑卷的步骤: 1、卸载卷,并执行强制检查 e2fsck -f /path/to/lv_devive 2、缩减逻辑边界 resize2fs /path/to/lv_device SIZE 3、缩减物理边界: lvreduce -L [-]size /path/to/lv_device 4、挂载卷
