Regarding inode
Hello,
I would like to know regarding inode.
[ENVIRONMENT]
RHEL 3 up5
[QUESTION]
1. When some file is created at ext3 file system, what algorithm is inode created ?
And who does inode assign ? For example, part of kernel's file system module, so on.
2. Could you tell me the inode order ?
For example, we can use inode from 1 to 10, and from 1 to 7 are used, and 8,9,10 is not used.
At above situation, inode's 3 is deleted, and when next file is created, what inode is used ?
Is inode's 3 used ? or are inode's 8 or 9 or 10 used ?
Thank you for advice.
Best Regards.

Re: Regarding inode
Currently ext3 and ext4dev allocate inodes in linear order within each block groups.
A file system contains a variable number of block groups. So, it depends on which block group your file is created.
