Details

This tool creates a Linux NSS pool Snapshot on a specified device.

It uses the Virtual File Services (Originally called Virtual File Services for NetWare) which were ported over to Linux. The SDK for this API set can be downloaded from http://developer.novell.com/wiki/index.php/Virtual_File_Services_for_NetWare. The objective of the tool is to creat a Linux NSS Pool Snapshot on a specified drive using XML as specified in the VFS for NetWare specification. It is intended to be used as a sample script for developers that may want to use the VFS API set to view and manage storage.

How to Use the file:

linuxAddPool.pl is a Perl script. So Perl must be installed and running on the NetWare server that this file is being loaded on. NSS must be installed to get the VFS support.

To run the perl script type:

perl linuxAddPoolSnapshot.pl POOL_NAME FREE_SPACE_DRIVE_ID NUMBER_OF_SECTORS SNAP_NAME

Where POOL_NAME is the name of the pool to create a snapshot of.
Where FREE_SPACE_DRIVE_ID is the name of the linux drive that will store the snapshot data.
Where NUMBER_OF_SECTORS is the number of sectors on the drive to allocate for the sanpshot.
And where SNAP_NAME is the name of the new snapshot pool.

Example:

perl linuxAddPoolSnapshot.pl NSSPOOL sdb 61440 NSSPOOL_SNAP

Sample output:

ran:/a # perl linuxAddPoolSnapshot.pl /dev/evms/NSS1 sdb 61440 snap
