Summary
An advance client installation on Linux is successful, but the following message displays during the installation and is added to the client installation log: Requirements for space in volume groups are not satisfied. The minimum recommended free space is 10% (10% of used space of all the logical volumes in a volume group) Free Space is not available on the following volume groups Please increase space on these volumes after Installation: Volumes: VolGroup00Press Enter to continue:
Symptoms
An advance client installation on Linux displays a warning message during the installation when the logical volume groups do not have 10% free extent.
The block level backup also fails when the logical volume groups have less than 10% free extent.
Command "/sbin/lvcreate --snapshot --size 921M --name bex_snapshot.812241318 /dev/VolGroup00/LogVol00" failed, exit code = 5: (Insufficient free extents (1) in volume group VolGroup00: 29 required)
Resolution
- LVM with ext2, ext3, Reiser
- Linux distribution - Redhat, Suse (not OES), CentOS
- To determine your Linux distribution, run the following command: cat /etc/*release* and uname -a
- Logical groups should have at least 10% free extent
- iSCSI package is required. (For IA map)
Run the command Vgdisplay through a Putty session to the Linux client.

Vgdisplay Output Details
PE is a physical extent, which is a small piece in a partition. Volume groups are made up of several PEs.
In the preceding output, there are 2,380 PEs in the volume group. Each PE size is 32 MB. The total volume group size is 2380 x 32 MB.
The first zero in the Free PE / Size 0/0 line in the output represents the number of free PEs and the second zero represents the size of each PE. In the preceding output, there are zero free PEs, so you must add PEs.
To Add PEs:
- Locate a free partition with free space in a disk. Create a new partition labeled as Linux LVM and then run pvcreate.
- Or, add a new disk to the Linux node and then create a partition for Linux LVM.
