The following requirements apply to NSS on NetWare® and Linux:
A server running OES NetWare or OES Linux
At least 10 MB free space on the server storage for each NSS volume you plan to create, up to the combined space you want to allocate to NSS volumes
A physical or logical device up to 2 TB in size and with free space available
The following requirements apply to NSS on Linux, regardless of the volume manager used:
You must select NSS from the Software options on the Installation Settings page in the YaST install; it is not installed by default.
If you did not install NSS during the OES installation, you can install it and its dependencies later from YaST.
OES Linux uses a Linux traditional file system for its system volume, such as ReiserFS.
After installing OES Linux, install only approved updates. If unapproved updates are installed, NSS cannot load. Refer to the OES Linux Installation Guide to install the approved updates.
The server must have a Novell® eDirectory™ Read/Write replica available when you create an NSS pool or volume on Linux; otherwise, NCP™ cannot map to the pool or volume.
The device where you want to create NSS volumes must be managed by EVMS if you plan to use the Storage plug-in to iManager or NSSMU to create and manage NSS partitions, pools, and volumes.
Linux uses Linux Volume Manager (LVM) as its default volume manager. With the Linux 2.6 kernel, any disk managed by the LVM cannot be managed by Enterprise Volume Management System (EVMS). Thus, the disk(s) where the boot partition (such as /boot for Grub) and system partition (such as /root for the swap and system volumes) reside are typically unavailable to NSS.
To be able to create an NSS data volume on the same device as your boot partition or system partition, make sure to configure the device for EVMS during the install. For information, see
Installing Linux with EVMS as the Volume Manager of the System Device
in the
OES Linux Installation Guide
.
When your data volumes are on non-system devices, do not configure devices during the install. Instead, leave the devices as unconfigured free space and do not assign a volume manager for them. After the install, create the volumes with NSSMU or the Storage plug-in to iManager.
If you want to use other volume managers instead of EVMS, you must manage NSS pools and volumes with Linux and NSS commands and utilities. Some capabilities of NSS are unavailable. For more information, see Section 22.0, Using NSS on Devices Managed by Non-EVMS Volume Managers.
