如何恢复 LVM 卷的缩小

如何恢复 LVM 卷的缩小

我有一个大约 400 GB 的 Linux LVM 卷。我按照以下步骤将其缩小到 217 GB。

umount /local
e2fsck -f /dev/mapper/vg00-lvol2
resize2fs /dev/mapper/vg00-lvol2 217G
lvresize -L 217G /dev/mapper/vg00-lvol2
lvdisplay /dev/mapper/vg00-lvol2
mount /local

然后我用 将物理卷的大小调整为 260 GB pvresize。如果我这样做,pvdisplay现在lvdisplay我得到:

lvm> pvdisplay
  --- Physical volume ---
  PV Name               /dev/sda3
  VG Name               vg00
  PV Size               260.00 GB / not usable 31.81 MB
  Allocatable           yes 
  PE Size (KByte)       32768
  Total PE              8319
  Free PE               250
  Allocated PE          8069
  PV UUID               6itmL0-3HAd-tmhA-a3u3-ketO-H7OO-MahFc7

lvm> lvdisplay
  --- Logical volume ---
  LV Name                /dev/vg00/lvol1
  VG Name                vg00
  LV UUID                JFATdC-lqxK-wsBc-VgL1-33Xv-PUfb-Y28fk2
  LV Write Access        read/write
  LV Status              available
  # open                 1
  LV Size                35.16 GB
  Current LE             1125
  Segments               1
  Allocation             inherit
  Read ahead sectors     auto
  - currently set to     256
  Block device           253:0

  --- Logical volume ---
  LV Name                /dev/vg00/lvol2
  VG Name                vg00
  LV UUID                F81eoe-xokM-Jqwr-NXND-VujX-BwN6-Kh0zZa
  LV Write Access        read/write
  LV Status              available
  # open                 1
  LV Size                217.00 GB
  Current LE             6944
  Segments               1
  Allocation             inherit
  Read ahead sectors     auto
  - currently set to     256
  Block device           253:1

我如何恢复这些步骤?也就是说,将物理卷和逻辑卷的大小调整回其原始大小。

答案1

我建议您颠倒一下顺序:

 pvresize
 lvresize
 resize2fs

我这里遗漏了什么吗?
