Hi, Thanks for your question. It looks like it uses bytes. The du command can also give the space consumed. This thread has some more information. [URL]   Lets us know if you have any additional questions.
Hello, Re: PowerScale (Isilon) H500 One FS 9.3.0.4 I'm trying to generate a quotas report by running the following ISI command: The value  16492674416640 would indicate the hard quota, correct? The value 11521920630784 would indicate actual consumed storage, correct? Are these values given in bytes, bits, kibibits? I need to report on consumed converted to TB (not TiB). Thank you.
