在我的240 GB SSD上,我最初有两个分区,一个包含Linux Mint的逻辑卷,另一个包含与Windows共享的NTFS分区。现在,我删除了NTFS分区,并希望扩展我的逻辑卷组以使用释放的磁盘空间。
如何扩展卷组,包含/ home的逻辑卷和/ home上的文件系统(ext4)?这可以在线吗?
PS:是的,我知道我必须备份我的数据:)
/dev/sdb/ (240GB)
linuxvg (160GB) should use 100% of the disk space
swap
root
home (ext4, 128GB) should be extended to use the remaining space

,而不是完全删除该分区。如果增加了现有的PV分区,则可能必须重新启动,因为Linux拒绝在使用磁盘时重新读取分区表。在线解决此问题很尴尬。-请显示您当前的分区表。
