The Root (/) Slice

The root (/) slice on your local disk must have enough space for the various files and directories as well as space for the device inodes in /devices and symbolic links in /dev.

The root slice also must be large enough to hold the following:

• Solaris system software

• Sun Cluster, some components from your volume management software, and any third party software packages

• Data space for symbolic links in /dev for the disk units and for volume manager use

Sun Cluster uses various shell scripts that run as root processes. For this reason, the /.cshrc* and /.profile files for user root should be empty or non-existent on the cluster nodes.

Your cluster might require a larger root file system if it contains large numbers of disk drives.

If you run out of free space, you must reinstall the operating environment on all cluster nodes to obtain additional free space in the root slice. Make sure at least 20 percent of the total space on the root slice is left free.
