Hello:
I am trying to set up user quotas on my /var partition to enforce limits on user's mailbox sizes. The machine is running CentOS 5.
When I do this: /sbin/dumpe2fs /dev/md2 | grep 'Block size' Block size: 4096
That tells me the block size is 4k.
But, if I do: repquota /var
It is telling me that one of my users is currently using 10264 blocks. But, if I look at their mail file, it is 10493792 bytes, which means they should be using 2562 blocks or so.
Also, if I do: df /var
I get this Filesystem 1K-blocks Used Available Use% Mounted on /dev/md2 39674140 20401792 17224468 55% /var
Which tells me the blocks are 1K in size. The repquota result makes much more sense with a 1K block size.
Any idea why dumpe2fs is giving a 4K block size?
Thanks, Neil

the filesystem block size is basically the minimal used size for any allocated object.
But, if I do: repquota /var
It is telling me that one of my users is currently using 10264 blocks. But, if I look at their mail file, it is 10493792 bytes,
10493792/1024=10247 kilo bytes used
which means they should be using 2562 blocks or so.
no, the quota are expressed in kB units, not filesystem block unit.

Because they don't serve the same purpose.

Thanks for the information.
I assumed that because the quota reports in blocks, that meant file system blocks.
I read the man pages to try to find some documentation of the block size for quota but did not see anything specific.
Is the block size always 1K or can it change? If it can change, how do I find the current block size?
Thanks, Neil

No, this is just telling you how many 1k blocks are used, available, etc. It is a report on disk space usage, not file system allocation units or their sizes.
The man pages are a good source of information in this regard....
