重新调整磁盘分区linux / vm的大小
我运行
Linux客户端的VM Player,我想知道如何扩展磁盘?在VM播放器中,我提供了更多的磁盘空间,但我不确定如何将新的磁盘空间安装/扩展/连接到系统.
我的旧磁盘空间是14GB [root@localhost ~]# df -h / Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup-lv_root 14G 4.5G 8.2G 36% / 然后我扩展了它,现在我看到sda2是新的空间? [root@localhost ~]# fdisk -l Disk /dev/sda: 128.8 GB,128849018880 bytes 255 heads,63 sectors/track,15665 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000cd44d Device Boot Start End Blocks Id System /dev/sda1 * 1 64 512000 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 64 2611 20458496 8e Linux LVM Disk /dev/mapper/VolGroup-lv_root: 14.5 GB,14537457664 bytes 255 heads,1767 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/VolGroup-lv_swap: 6408 MB,6408896512 bytes 255 heads,779 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 我需要先安装新空间吗? resize2fs -p /dev/mapper/VolGroup-lv_root 108849018880 resize2fs 1.41.12 (17-May-2010) The containing partition (or device) is only 3549184 (4k) blocks.

如前所述,您首先要调整包含逻辑卷的分区的大小,而不是继续调整LVM大小.跟着这些步骤:
>使用fdisk -l -u / dev / sda记下当前分区设置(尤其是起始扇区) 这些指令对增加磁盘空间(扩展卷)有效 缩小卷在概念上是相似的,但您必须从文件系统收缩开始向后执行步骤.另外,如果您使用XFS或其他无法收缩的文件系统,则无法在没有备份/还原过程的情况下调整LVM卷的大小. (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
