VMware 扩容 Fedora 虚拟机磁盘后调整分区并拉伸文件系统
分类：System 标签：Vmware Fedora
Fedora 29 前两天已经 Final Freeze 了，准备从 Fedora 28 升级到 Fedora 29 。 之前创建虚拟机时，硬盘设置的有点小 upgrade 这种操作空间不够用，在 VMware 中把虚机硬盘扩容至 8 GiB 。 虚拟机 只有一个 / 分区，后面调整磁盘分区，拉伸文件系统，需要在 LiveOS 环境进行操作， 下载了一个 netinst ISO 安装镜像，重启引导进入安装 LiveOS 环境。
调整分区
查看当前分区的 起始位置 和 分区标记 ( Flags ) ：
[anaconda root@localhost /]# parted /dev/sda
GNU Parted 3.2
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) p
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sda: 8590MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 1049kB 5369MB 5368MB primary ext4 boot
删除旧分区：
(parted) rm 1
(parted) p
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sda: 8590MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
从原分区的 起始位置 开始新建 主分区 至 最大可用空间 ：
(parted) mkpart primary 1049kB 100%
(parted) p
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sda: 8590MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 1049kB 8590MB 8589MB primary lba
重新创建分区后，之前的 分区标记 Flags 丢失，重新设置 boot 不然无法启动：
(parted) set 1 boot on
(parted) p
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sda: 8590MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 1049kB 8590MB 8589MB primary boot, lba
(parted) set 1 lba off
(parted) p
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sda: 8590MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 1049kB 8590MB 8589MB primary boot
(parted) q
Information: You may need to update /etc/fstab.
TIPS： 使用 growpart 可以更简单的扩展分区，树莓派就是用 growpart 扩展 SD 卡分区的：

文件系统自检
分区调整好后，使用 e2fsck 自检 分区上的文件系统：
[anaconda root@localhost /]# e2fsck -fv /dev/sda1
e2fsck 1.44.3 (10-July-2018)
Superblock last write time is in the future.
(by less than a day, probably due to the hardware clock being incorrectly set)
Pass 1: Checking inodes, blocks, and sizes
Inode 138584 extent tree (at level 1) could be shorter. Fix<y>? yes
Inode 282934 extent tree (at level 1) could be shorter. Fix<y>? yes
Pass 1E: Optimizing extent trees
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information

文件系统扩容
使用 resize2fs 对文件系统进行拉伸：
[anaconda root@localhost /]# resize2fs /dev/sda1
resize2fs 1.44.3 (10-July-2018)
Resizing the filesystem on /dev/sda1 to 2096896 (4k) blocks.
The filesystem on /dev/sda1 is now 2096896 (4k) blocks long.
使用 dumpe2fs 确认文件系统大小：How to find the size of a filesystem ?
# echo 1024*1024*1024|bc
1073741824
# dumpe2fs -h /dev/sda1 |& awk -F: '/Block count/{count=$2} /Block size/{size=$2} END{print count*size/1073741824}'
7.99902
也可以挂载 /dev/sda1 到 /mnt 查看大小：
[anaconda root@localhost /]# mount /dev/sda1 /mnt
[anaconda root@localhost /]# lsblk
