When a file system is created during installation, one of the following warning messages might be displayed:
Warning: inode blocks/cyl group (87) >= data blocks (63) in last cylinder group. This implies 1008 sector(s) cannot be allocated.
Warning: 1 sector(s) in last cylinder unallocated
The warning occurs when the size of the file system that you created does not equal the space on the disk that is being used. This discrepancy can result in unused space on the disk that is not incorporated into the indicated file system. This unused space is not available for use by other file systems.
Workaround: Ignore the warning message.
