determine number of inodes and max number of inodes

[Donald Thaler]

How does one determine the max number of inodes available and the number of inodes currently being used. Also I have 8 30gb (240)drives and when i add up the total number of space allocated to the logical devices I come up with 222gb out of 240 gb. Is this 18 gb available to be allocated?

Hi,

"sar -v 3 33" will give this info.

I think you may get that information by looking at:
kmtune |grep inode

Then to see how many are in use, go to glance, enter "M" for Mem Rpt, enter "t", then enter the plus symbol, i.e "+"

Hope that helps
Andy

bdf -i will show on a per filesystem basis the number of inodes.

What type of enclosure are the disks part of? For instance, an autoraid will reserve space for a hot spare which will consume disk space. If just jbod, what is the max pe per pv value in vgdisplay output? Does vgdisplay show any 'free pe' in the vg?
