[LU-1101] ncorrect permission handling when creating existing directories

• Type: Bug
• Resolution: Duplicate
• Priority: Critical
• Affects Version/s: Lustre 2.1.0
• Environment: Lustre 2.1 on clients and servers, Scientific Linux 5
• Severity: 3
• Bugzilla ID: 23,459
• Assignee: WC Triage
• Reporter: Marek Magrys

Description

Lustre seems to handle permissions on mkdir incorectlly in some cases. This issue makes it hard (or impossible) to use Torque scheduler directly on top of a Lustre filesystem. This is in fact copy of bugzilla bug #23459, which was reported by us some time ago for 1.8 branch, however it looks like the bug is still there even in 2.1. All the symptoms described in bugzilla are identical and the reproducer code provided by Lukasz Flis still works for this issue.
