This works as expected. From the help output:
-w, --warning=INTEGER
Exit with WARNING status if less than INTEGER units of disk are free
-w, --warning=PERCENT%
Exit with WARNING status if less than PERCENT of disk space is free
-c, --critical=INTEGER
Exit with CRITICAL status if less than INTEGER units of disk are free
-c, --critical=PERCENT%
Exit with CRITICAL status if less than PERCENT of disk space is free
If you want to specify inode limits, you need to specify:
-W, --iwarning=PERCENT%
Exit with WARNING status if less than PERCENT of inode space is free
-K, --icritical=PERCENT%
Exit with CRITICAL status if less than PERCENT of inode space is free
Cheers, Jan.
