Introduction

In the past, Lustre quotas frequently caused problems. One reason are numerous implementation changes, e.g. due to adaptions to underlying file systems.

Recently, the bug explained in https://jira.hpdd.intel.com/browse/LU-4345 ( fix for b2_5 branch at http://review.whamcloud.com/11435 ) caused quotas to be forged. If you have been running file systems with version Lustre 2.4 your quotas are probably still (slightly) incorrect.

During the first part of his talk at LAD'15 Roland Laifer explained tools for wrong quota investigation. Below you can find links to the tools and further information.
