Hi Niu, I've enabled quota during formatting, do I still need to enable it by lctl?

You can check this in the "quota_slave/info" of each osd proc dir. (for instance, proc/fs/lustre/osd-ldiskfs/lustre-OST0000/quota_slave/info)-----Original Message----- From: lustre-discuss-boun...@lists.lustre.org [mailto:lustre-discuss-boun...@lists.lustre.org] On Behalf Of Chan Ching Yu Patrick Sent: Wednesday, March 05, 2014 11:25 AM To: lustre-discuss@lists.lustre.org Subject: [Lustre-discuss] Lustre Quota over Hard Limit Hi, I'm testing quota with latest maintenance release (Lustre 2.4.2). I found that Lustre still allow the users to write the file over hard limit. Let's see the example below. I've set 500MB soft limit and 530MB hard limit. But I can write a 700MB file.
