Re: how to resize a partition of a disk define as a physical volume

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I should have added the output of pvs:

[root ~]# pvs
  PV         VG          Fmt  Attr PSize PFree
  /dev/xvda2 cl_vm731611 lvm2 a--  9.00g    0

PFree still show 0. It should show 5g.

Also:
[root ~]# pvdisplay /dev/xvda2
  --- Physical volume ---
  PV Name               /dev/xvda2
  VG Name               cl_vm731611
  PV Size               9.00 GiB / not usable 2.00 MiB
  Allocatable           yes (but full)
  PE Size               4.00 MiB
  Total PE              2303
  Free PE               0
  Allocated PE          2303
  PV UUID               RtXa0c-07RP-RJ0V-kSjC-Tuo0-5QQv-sQIKlr


With fdisk, we can see the additional space has is there as it shows 16GB.
The original disk had 10GB.
[root ~]# fdisk  -l /dev/xvda

Disk /dev/xvda: 16.1 GB, 16106127360 bytes, 31457280 sectors
[snip]

    Device Boot      Start         End      Blocks   Id  System
/dev/xvda1   *        2048     2099199     1048576   83  Linux
/dev/xvda2         2099200    20971519     9436160   8e  Linux LVM


vgs also shows 0 Free PE:
[root@CTSSVN01 ~]# vgs
  VG          #PV #LV #SN Attr   VSize VFree
  cl_vm731611   1   2   0 wz--n- 9.00g    0


Thanks,
