- The literature on file systems (4.2 BSD) says that the cylinder block in
- every cylinder group contains a bit map of the available data blocks in that
- cylinder group. Every cylinder group also contains superblock information
- for reliability.The superblock already contains the list of all free data
- blocks for that file system. Is it not redundant to have free data blocks bit
- map in the cylinder blocks when it is already there in the superblocks ?
- Kindly correct me.
