Directories that Reside on CFS
The following table shows a recommended example on how to design
SAP file systems for CFS shared access.
The table can be used to document used volume or disk groups across all
cluster nodes.
The /usr/sap/tmp might or might not be part of the local root file
system. This is the working directory of the operating system collector
process saposcol. The size of this directory will rarely be beyond a few
Megabytes.
