Purpose

 This note is describing how a Siebel filesystem directory structure can be changed when using multiple file system paths ( partitions ).

Reason for a reorganization of the Siebel Filesystem could be, among others: 

- The move from a single folder architecture  to a partitioned folder architecture ( Multiple File system paths )

- For systems already partitioned , need to repartition as current configuration exceeding disk space

- The need to transform systems using the pre-8.1 imbalanced multiple folder structure to the supported partition scheme 

(Note: this pre-8.1 multiple folder structure refers to a setup where first filesystem folder adds new files, and all subsequent folders contain older files in read-only mode. This workaround has been used in 7.8 deployments when there was a need to split the filesystem into different folders. Although this is still working in 8.1 for most areas, this is not supported anymore and can cause issues, for example in the BIP area. See note 1497801.1 - SBL-GEN-0000x error after configuring Siebel Reports 8.1.1.7FP. When such setup has been chosen historically, the suggestion is to reorganize using sfspartition to be fully supported in version 8.1) 

There might be other reasons not mentioned here which require partitioning or re-partitioning of large production file systems. 

With Siebel 8.1 this task  requires the use of the sfspartition tool.

 The execution of sfspartition on large Terrabyte  file systems with millions of files in it can be time consuming.

It can happen that this utility needs to run many hours in order to copy files from one shared drive to another for example. 

This note is describing how such a reorganization can be achieved with minimal downtime for production. 

Scope

This document is offered to Siebel system administrators looking for mitigating the Siebel file system reorganization execution time.

Applicable to latest Siebel CRM releases as well.
