Re: [CentOS] df -h shows system at 100% used, but there is space left

Has anyone seen output like this before? Notice on my /dev/md0 That it reports 100% used, but also 5.3 Gb available. What would cause this?

# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 71G 1.6G 66G 3% / /dev/sda1 99M 22M 73M 23% /boot tmpfs 506M 0 506M 0% /dev/shm /dev/md0 903G 851G 5.3G 100% /home

I've never run into the reserved blocks being an issue (even though it may be the case here). I have run out of inodes (one per file, and if you have a ton of little files...). Run df -i to see what percent inodes your using.

Wikipedia has a good explaination of inodes (http://en.wikipedia.org/wiki/Inode).
