    inodes are used for file entries.  Each file/directory uses an inode.
When you run out of inodes, you can't create any more files, no matter
how much space you have left.

            
      "df -i" will show inode usage.

root@server# fstyp /dev/dsk/c0t0s0
ufs
root@server# df -o i /
Filesystem             iused   ifree  %iused    Mounted on
/dev/dsk/c0t0s0       1258550      0     100%   /



   The only way to free up inodes is to delete some files/directories.
You must have a lot of files or directories somewhere to be using up
all your inodes when you have 50% of the disk left.  Once you find
out where all the files are, you can delete some, or possible tar
them up so they only take up a single inode.
