Re: df -k confusion

Hi Rajesh,

The reason they don't match could be :

1. Some blocks are reserved while creating the FILE SYSTEM so that they can be utilized when you scan your disk for the bad block... and bad blocks are discovered. When bad blocks are discovered these reserved are used in place of those blocks.
2. There are some bad blocks already present in the file system.

Hope this clarifies your doubt to some extent.. Your SYS ADM.. will be the best person to explain you the same.

Thanks

Nikunj
