How to convert KB to "Blocks and Inodes" or quota

Hi! I have set up quota on my system but now I need to know how to convert say 5MB to blocks. And what are inodes? I know they are "pointers" but how much should one generally give a user?

For example, here is a setup of one user on the machine:

Code:

*** Report for user quotas on device /dev/sdax
Block grace time: 7days; Inode grace time: 7days
                        Block limits                File limits
User            used    soft    hard  grace    used  soft  hard  grace
----------------------------------------------------------------------
user1     --      44       0    1500             11     0  1500

To me, that looks like user1 has about 1.5MB of HD space and 1.5MB of inode space (which I really don't know what that's for.)

Does anyone know what I am talking about? Thanks!

Ok, another thing.

So what seems to be the case is that

1000 blocks = 1M; so my initial presumption was correct. Now, does anyone know how many inodes I should set up for my user? Say I want him to have 5MB of HD space. If I gave him 5MB of inode space, does that mean the MAX space he could take up is 10MB?

Also, an inode is a "file pointer," yes? So if I set the inode size very small, he could only upload a few files before his inode space was maxed out. But if I changed the inode size to be large, he could store much more files until he exceeded the block space or inode space, which ever comes first.

Is that correct? Thanks again!

you're very welcome...

by the way, i just noticed that howto is from '97...
