[Solved] Undo vgextend

Hi

I had extended one of the FS yesterday as rsync was failing and the temp solution was to extend it to 4GB while we worked on cron script.

Code:

spthrv01:/root# bdf /p05
Filesystem          kbytes    used   avail %used Mounted on
/dev/vg232/lvol1   130940928 82208608 48385792   63% /p05

spthrv01:/root# lvdisplay /dev/vg232/lvol1
--- Logical volumes ---
LV Name                     /dev/vg232/lvol1
VG Name                     /dev/vg232
LV Permission               read/write   
LV Status                   available/syncd           
Mirror copies               0            
Consistency Recovery        MWC                 
Schedule                    parallel     
LV Size (Mbytes)            127872          
Current LE                  3996      
Allocated PE                3996        
Stripes                     0       
Stripe Size (Kbytes)        0                   
Bad block                   NONE         
Allocation                  PVG-strict/distributed
IO Timeout (Seconds)        default             

###As you can see, there no PE left anymore:

spthrv01:/root# vgdisplay /dev/vg232
--- Volume groups ---
VG Name                     /dev/vg232

Open LV                     1      
Max PV                      16

Max PE per PV               16000        
VGDA                        8   
PE Size (Mbytes)            32

this is what I have done yesterday:

Code:

lvextend -L 127872 /dev/vg232/lvol1

fsadm -F vxfs -b 127872M /p05

Please advise as to which command would be best used to undo the vgextend. vgreduce requires to take out the disk but theres tons of data there and i want them there...thanks in advance..

vgextend

VGEXTEND(8)						      System Manager's Manual						       VGEXTEND(8)

NAME
       vgextend - add physical volumes to a volume group

SYNOPSIS
       vgextend  [-A|--autobackup  y|n]  [-d|--debug]  [-h|-?|--help] [--restoremissing] [-f|--force] [-t|--test] [-v|--verbose] [ PHYSICAL DEVICE
       OPTIONS ] VolumeGroupName PhysicalDevicePath [PhysicalDevicePath...]

DESCRIPTION
       vgextend allows you to add one or more initialized physical volumes ( see pvcreate(8) ) to an existing volume group to extend it  in  size.
       Moreover,  it  allows  you to re-add a physical volume that has gone missing previously, due to a transient device failure, without re-ini-
       tialising it. Use vgextend --restoremissing to that effect.

       If PhysicalDevicePath was not previously configured for LVM with pvcreate (8), the device will be initialized with the same default  values
       used  with  pvcreate.  If non-default pvcreate values are are desired, they may be given on the commandline with the same options as pvcre-
       ate.  See PHYSICAL DEVICE OPTIONS for available options.  Note that the restore-related options such as --restorefile, --uuid, and --physi-
       calvolumesize are not available.  If a restore operation is needed, use pvcreate (8) and vgcfgrestore (8).

OPTIONS
       See lvm for common options.

PHYSICAL DEVICE OPTIONS
       The  following  options	are  available	for initializing physical devices in the volume group.	These options are further described in the
       pvcreate man page.

       -f, --force

       -y, --yes

       -Z, --zero y|n

       --labelsector sector

       --metadatasize size

       [--metadataignorey|n]

       --pvmetadatacopies copies

       --dataalignment alignment

       --dataalignmentoffset alignment_offset

Examples
       "vgextend vg00 /dev/sda4 /dev/sdn1" tries to extend the existing volume group "vg00"  by  the  new  physical  volumes  (see  pvcreate(8)  )
       "/dev/sdn1" and /dev/sda4".
