Sun Cluster Software Installation Guide for Solaris OS

Example—Sample File-System Allocations

Table 1–2 shows a partitioning scheme for a cluster node that has less than 750 Mbytes of physical memory. This scheme is to be installed with the End User Solaris Software Group, Sun Cluster software, and the Sun Cluster HA for NFS data service. The last slice on the disk, slice 7, is allocated with a small amount of space for volume-manager use.

This layout allows for the use of either Solstice DiskSuite or Solaris Volume Manager software or VxVM software. If you use Solstice DiskSuite or Solaris Volume Manager software, you use slice 7 for the state database replica. If you use VxVM, you later free slice 7 by assigning the slice a zero length. This layout provides the necessary two free slices, 4 and 7, as well as provides for unused space at the end of the disk.

Table 1–2 Example File-System Allocation



Allocation (in Mbytes) 




Remaining free space on the disk after allocating space to slices 1 through 7. Used for the Solaris OS, Sun Cluster software, data-services software, volume-manager software, Sun Management Center agent and Sun Cluster module agent packages, root file systems, and database and application software. 



512 Mbytes for the Solaris OS. 

512 Mbytes for Sun Cluster software. 



The entire disk. 



The Sun Cluster software later assigns this slice a different mount point and mounts the slice as a cluster file system. 


Available as a free slice for encapsulating the root disk under VxVM. 





volume manager 


Used by Solstice DiskSuite or Solaris Volume Manager software for the state database replica, or used by VxVM for installation after you free the slice.
