[Lustre-discuss] Lustre problem

[Hans-Juergen Schnitzer]

Hi,

Occasionally, operations on a file or directory like "ls -l" fails with 
"permission denied". When this happens I see the following error 
messages in the client logs:

LustreError: 23545:0:(mdc_locks.c:420:mdc_enqueue()) ldlm_cli_enqueue: -2

The lustre version is 1.6.2, the OS Scientific Linux 5.0.
Any help would be appreciated.
