If you have gnu df, (it's in /opt/sfw/bin/gdf if you've installed the companion
CD), then that supports the -i flag.
Alternatively parse the output from df -g. I have a horrid script that does
something like that, fragment here:
echo "Filesystem iused ifree %iused Mounted on"
for ZF in ${FSLIST}
do
OUT=`/usr/sbin/df -g ${ZF} | awk -F: '{print $NF}'`
NFILES=`echo $OUT | awk '{print $15}'`
NFREE=`echo $OUT | awk '{print $18}'`
NUSED=$(($NFILES-$NFREE))
NPERC=$(((100*NUSED)/NFILES))
SPACE=`/usr/sbin/df -k ${ZF} | nawk '/%/{print $3}'`
echo "${ZF} $NUSED $NFREE ${NPERC}% ${ZF}"
echo " average $(($SPACE/$NUSED))k"
done
ZFS goes up to ridiculous number of files. Here's one of ours
which has a fair number:
Filesystem iused ifree %iused Mounted on
/images/fred 140738056 36000718887 0% /images/fred
average 11k
I've never seen ZFS run out of inodes, though.
