Question on inodes

Hi Guys,

I bought a new disk the other day and when I formatted it with mke2fs I had to
specify the "bytes per inode" for the partition.

What I am in need of is a clarification as to what this actually means.

For example if I specify the "bytes-per-inode" value as 2048 then what happens
is that for every 2048 bytes on the disk an inode will be created.

The disk was bought to be a news partition and if there are heaps and heaps of
small files on the disk, then if there are not enough inodes on the partition
there will reach a stage where no more files can be created.

For each file created on the disk one inode is used, regardless of the size of
the actual file.

For example, using the above hypothetical situation. If I set the "bytes-per-inode"
value to 2048, and then I filled the partition with millions of 1024 byte files,
then I would actually run out of inodes first before I ran out of disk space.

Can someone please clarify this for me.

Many Thanks
Graham
