Query related to Inodes in Solaris
Hi friends,
1.From the information I gathered, an inode is an object which has a number associated with it... and when a slice is partitioned, inodes with their numbers are created.
When a file is created, an inode number is assigned to it. This could be viewed through ls -i <dir/file> command. Each inode has 2 pointers, 1 pointer pointing to block containing properties of a file/dir and other pointer points to data blocks for the file.
2.Now, please clarify my doubts:
1.What is the basic size of an inode in Solaris ? (for eg, in linux its 128 bytes). So, if it is 128 bytes, does it mean that the size of a file can only be 128 bytes..?.
2.What is the need for increasing the number of bytes per inode by means of
newfs -i <raw device> command?
thank u.
