Missing INODEs in an ext3 file system

Your inodes available and used kinda match... all your inodes are used, a few thousand dirs and 11million files is quite a lot and also you reckon... can you find out exactly.

Are they all small ish files?

You can create file systems with more inodes (at least you can on other *nix) if you need them

ASKER

Thanks for picking up the question, jools, but you didn't read it fully.

I know that I've used up the inodes, but I don't understand why 11 million files are using 19 million inodes, when there are only a few thousand directories.

11 million is a lot and yes, they are small. They are using 65% of the diskspace and 100% of inodes.I can mount another file system, but I'd like to understand what's happening with this one.

Would you say that there is a 10% difference in the numbers?

I'm wondering if they are reserved for the root user like the file system space, just checking the technotes to find out

9 milion out of 19 milion is quit big number and I don't think it has to do with reservations.

I've just had a look at one of my systems

There are differences but mine is obviously smaller.
# find /home | wc -l

# df -i /home

/dev/mapper/rootvg-home

still trying to find the technote on it (large database and all that) google just come up with the usual results, one inode per file. It may however have something to do with soft or hard linked files... still looking

ASKER

Apologies, I've moved the goal posts slightly by purging some files (approx 2 million). There are still 17 million inodes used.

Here is the tune2fs:

omarfarid, I'm just checking if there are any issues with unmounting the filesystem. I don't believe there should be, but this is an Amazon EC2 instance, so I'm not on familiar territory.

when I sow that it is mounted over /mnt , I thought your are testing with it, etc

ASKER

I need to apologise for wasting your time. I've just counted the files again and I must have been suffering from a fit of madness. I somehow got my count very wrong. It transpires that the INODE file count correlation is very close, as you'd expect. Thanks for sticking with me, guys. I need to drink more coffee.

Apologies again and thanks for the company!

Crikey, so omarfarid must have had a vision as he posted saying 9 million files before we knew about it....
How about some lottery numbers for tonight omar?

Thx for the question btw, something to get the grey matter working...

oh well, I thought we'd found a quirky ext3 file system for a minute....

I still want those lotto numbers omar :-)
