linux – pvresize在增加底层块设备的大小后似乎没有调整大小

前端之家收集整理的这篇文章主要介绍了linux – pvresize在增加底层块设备的大小后似乎没有调整大小前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
增加了我用作LVM PV的分区大小,但运行pvresize似乎没有看到额外的空间:
cuttle:~# fdisk -l /dev/vda

Disk /dev/vda: 21.5 GB,21474836480 bytes
255 heads,63 sectors/track,2610 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: 0x00027dbb

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1   *           1          31      248976   83  Linux
/dev/vda2              32        2610    20715817+  8e  Linux LVM

其中说vda2约为20gig

cuttle:~# pvdisplay
  --- Physical volume ---
  PV Name               /dev/vda2
  VG Name               debian
  PV Size               4.76 GiB / not usable 3.08 MiB
  Allocatable           yes (but full)
  PE Size               4.00 MiB
  Total PE              1217
  Free PE               0
  Allocated PE          1217
  PV UUID               tehZic-5vfN-rsrm-B8lN-lpgc-yQT1-ioH1V0

所以目前的pv约为4-5演出

cuttle:~# pvresize -v /dev/vda2
    Using physical volume(s) on command line
    Archiving volume group "debian" Metadata (seqno 12).
    No change to size of physical volume /dev/vda2.
    Resizing volume "/dev/vda2" to 9975981 sectors.
    Updating physical volume "/dev/vda2"
    Creating volume group backup "/etc/lvm/backup/debian" (seqno 13).
  Physical volume "/dev/vda2" changed
  1 physical volume(s) resized / 0 physical volume(s) not resized

pvresize说“物理卷大小/ dev / vda2没有变化”

cuttle:~# pvdisplay
  --- Physical volume ---
  PV Name               /dev/vda2
  VG Name               debian
  PV Size               4.76 GiB / not usable 3.08 MiB
  Allocatable           yes (but full)
  PE Size               4.00 MiB
  Total PE              1217
  Free PE               0
  Allocated PE          1217
  PV UUID               tehZic-5vfN-rsrm-B8lN-lpgc-yQT1-ioH1V0

并且光伏的大小没有改变.

不知道我还可以做些什么来使用额外的空间.我想我可以将分区大小调整为pv的大小,然后添加第二个分区,但在我看来,我在这里尝试做的事情应该可行.

解决方法

partprobe / dev / vda

man partprobe

NAME
partprobe – inform the OS of partition table changes

SYNOPSIS partprobe [-d] [-s] [devices…]
