inode on 11.31

[Joao Rei]

Hi,

This is a 11.31 ia64 system.

I've create a 550000 MB filesystem:

newfs -F vxfs -o largefiles /dev/eva01/rpsapd

Now I see from the bdf output that the (used + avail) space is 35000 MB less than Total kbytes.

I suppose this is because of the huge number of inodes created (256 bytes each, millions of them).

The question is:

How can I limit the number of inodes on this filesystem. I just need a few hundreds.

I'm "loosing" 35GB of disk space.

Thanks,

Best Regards,

Joao Rei

Hi,

/dev/eva4r0v1/psapd
563200000 155127 527854576 0% /oracle/psapd

527854576/1024 = 515482,984375 -> 50GB

This quit normal, veritas filesystem(vxfs) will use about 8 % for administration.

Best regards,

If you are using that filesystem for a database you won't be needing millions of inodes, just a few hundred. 35GB seems to be a lot of wasted space!!

In previous versions of hpux, I have an ideia that it was possible to limit the number of inodes using newfs. But on 11.31 it seems to be now an invalid option. Perhaps some guru on this forum can help you ...
