Description

The CEA Bull customer reported two crashes when doing I/O benchmarks on a Lustre FS with quota activated.
After a quotaoff, the crash didn't happen anymore. Here's the signature :

LustreError: 29856:0:(osd_handler.c:1967:osd_object_ref_del())
ASSERTION(inode->i_nlink > 0) failed
Pid: 29856, comm: mdt_24

As they provided a system dump, I have analysed it with crash and provided the trace in attachement (stack and content of inode structure).
