Question
Which of the following Linux filesystems pre-allocates a fixed number of inodes at filesystems make/creation time, and does NOT generate them as needed?
Options
- Aext3
- Bjfs
- Creiserfs
- Dxfs
Explanation
The ext3 filesystem pre-allocates a fixed number of inodes when it is created, unlike more modern filesystems that allocate them dynamically as needed.
Common mistakes.
- B. JFS (Journaled File System) is a dynamic inode allocation filesystem, meaning it allocates inodes as required rather than pre-allocating a fixed number.
- C. ReiserFS is a dynamic inode allocation filesystem, which allows it to generate inodes on the fly as files are created.
- D. XFS is a dynamic inode allocation filesystem, capable of expanding its inode allocation as the filesystem grows and new files are added.
