# This script should be run prior to running executing the filesystem tests.
# valid devices need to be passed for Device Mapper to work correctly
# 03/14/03 mridge@us.ibm.com added instance and time command line options
# 05/16/03 changed script paths
# 05/20/03 Added instructions on setup and warnings
# 05/03/2004 hien1@us.ibm.com  Added resize2fs and resize_reiserfs after extend and reduce LVs
# 05/03/2004 Moved the mount after resizing
# 05/03/2004 Modified /dev/ram to /dev/ram0

        fdisk needs to be run and the 4 HD partitions marked as 0x8e -- Linux LVM

        - If this is run on a 2.4 kernel system then LVM must be configured and the kernel rebuilt. In a 2.5 environment
        you must configure Device Mapper and install LVM2 from www.systina.com for the testcase to run correctly.

        - These operations are destructive so do NOT point the tests to partitions where the data shouldn't be overwritten.
        Once these tests are started all data in the partitions you point to will be destroyed.
