Full Discussion: Query related to Inodes in Solaris
Operating Systems Solaris Query related to Inodes in Solaris Post 302362721 by jp2542a on Saturday 17th of October 2009 06:13:55 AM

There are many resources to explain inodes in detail. Let me try to give you a basic understanding.

First, inodes are on disk descriptions of the storage allocation of a file in a filesystem. It does not contain the filename used to access the storage. It does contain the number of path names that refer to that storage.

Second, when a file is opened, a vnode is created that contains information from the inode. The OS only uses the vnode during file access.

Third, a file is located via it's directory entry. A directory entry basically consists of a file name and inode number. So when you open a file, the system searches for the directory containing the file entry. It then uses the inode entry to create a vnode.

Fourth... This size of the inode is not really useful. It does not determine file size. It only contains information that describes the information necessary to manage the file.

Fifth... the -i option of newfs refers to the density of inodes. That is.. how many inodes will be created. It is actually a mkfs option.

       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.
