Robert Bailey asks
Besides using quota report and adding up the "File Used" for all the qtrees, is there a simpler way to get a summary file usage on a volume?
Adam Fox replies:
df -i will tell you how many inodes are being used in a volume. However, that isn't just files, it's directories, symlinks, etc.
That last is also true of the "Files Used" value in "quota report" output. For that matter "maxfiles" (with no arguments, another way of getting the "df -i" information) also refers to inodes as "files" without qualification.
