Possible workarounds for these problems are:
(Recommended) Use Additional Disks for NSS Pools and Volumes: Use multiple devices
on the server, and reserve the system device for system partitions and Linux POSIX file
systems. Create NSS pools and volumes on the non-system disks only.
This solution does not require that the system device be managed by EVMS. During the install,
use LVM2 as the volume manager for the system device. Do not partition or configure the non-
system devices during the install. Otherwise, follow the install procedures described elsewhere
in this guide. Any free space on the LVM2-managed system device is not seen by NSS
management tools and is not available for creating NSS pools.
After the install, you can create NSS pools or Linux POSIX file systems on other EVMS-
managed devices.
(Supported) Modify the Partitioning Scheme During Install: At install time, modify the
partitioning scheme for the system device to use EVMS and to leave unpartitioned free space
available on the device that can be used later for NSS pools.
NOTE: This option applies to physical machines. With virtual machines, you can easily add a
second virtual disk to use for NSS pools and volumes.
Beginning in OES 2 SP2, the Partitioner in the YaST Install offers the Create EVMS Based
Proposal option. Follow the procedure in
EVMS," on page
After the install, you can create NSS pools or Linux POSIX file systems on the system device
and on any additional disks. For information about creating NSS and Linux POSIX file systems
on EVMS-managed devices, see
page 217.
A.2 Configuring the System Device to Use EVMS
Beginning in OES 2 SP2, the Partitioner in the YaST
Proposal option. For unpartitioned devices over 20 GB in size, this option creates a boot partition
and a system partition for the container that holds the swap and / (root) volumes.

A.2.1 Understanding the EVMS–Based Partitioning Scheme
Using EVMS to manage the system device allows you to later add NSS pools and volumes on any
unpartitioned free space on it. You must modify the partitioning scheme to use EVMS during the
install. It is not possible to change the volume manager for the system device after the install.
Beginning in OES 2 SP2, the Partitioner in the YaST Install offers the Create EVMS Based Proposal
option to automatically create an EVMS solution for the system device. For unpartitioned devices
over 20 GB in size, this option creates a boot partition and a container for the swap and / (root)
volumes in up to the first 20 GB, and leaves the remainder of the space on the device as
unpartitioned free space.
