记录一次RockyLinux UEFI磁盘迁移(扩展)

2020.03.10

使用任意软件, 例如傲梅, 进行磁盘一比一直接克隆
从新硬盘启动系统, 出现卡住的情况, 一般是复制的时候EFI分区UUID更改了(生成新的)

A stop job is running for dev-disk-by\x2duuid-6C02\x2dB99B.device

等待一会后, 键入root密码, 进入紧急模式

使用blkid查看块UUID, /dev/sda1正是EFI分区

/dev/sda1: SEC_TYPE="msdos" UUID="0000-4823" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="EFI system partition" PARTUUID="182ddd5c-fc1b-11ee-bc5d-c3b5b8bd8720"
/dev/sda2: UUID="fa5133df-3efe-40d8-8386-2599e0bc6417" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="182ddd60-fc1b-11ee-bc5d-c3b5b8bd8720"
/dev/sda3: UUID="LCzkNd-2bJU-hk6q-YIeS-RBnM-XY0f-u91TAG" TYPE="LVM2_member" PARTUUID="182ddd64-fc1b-11ee-bc5d-c3b5b8bd8720"
/dev/mapper/rl-root: UUID="0e5e4a9c-cbb1-40b4-ac83-7a5021b10e31" BLOCK_SIZE="512" TYPE="xfs"
/dev/mapper/rl-swap: UUID="717d74bc-390f-47b5-83ed-e9322bbcbbe3" TYPE="swap"
/dev/mapper/rl-home: UUID="013f7c16-aaa4-4346-b9c8-4bb02cc456cd" BLOCK_SIZE="512" TYPE="xfs"

修改/etc/fstab上/boot/efi的UUID, 重启即可

/dev/mapper/rl-root     /                       xfs     defaults        0 0
UUID=fa5133df-3efe-40d8-8386-2599e0bc6417 /boot                   xfs     defaults        0 0

/dev/mapper/rl-home     /home                   xfs     defaults        0 0
/dev/mapper/rl-swap     none                    swap    defaults        0 0

调整磁盘大小

parted /dev/sda

对LVM分区进行扩容

resizepart 3 100%

对分区物理卷进行扩容

pvresize /dev/sda3

使用pvs查看卷

  PV         VG Fmt  Attr PSize   PFree
  /dev/sda3  rl lvm2 a--  929.92g    0

使用vgdisplay查看卷组情况

  --- Volume group ---
  VG Name               rl
  System ID
  Format                lvm2
  Metadata Areas        1

  VG Access             read/write

  VG UUID               rFnljf-9GxD-tS5t-8b6e-esEc-E2Jc-Lg2tpC

扩展root卷大小

lvextend -l +100%FREE /dev/mapper/rl-root

同步root卷文件系统

xfs_growfs /dev/mapper/rl-root

使用df -h查看磁盘情况

Filesystem           Size  Used Avail Use% Mounted on
devtmpfs              16G     0   16G   0% /dev
