[lustre-discuss] RobinHood fail on Lustre IEEL v2.5

[Langton]

I am trying to install Robin Hood to manage a 4PB lustre filesystem.
The environment is as follows
IEEL Lustre 2.5
Robinhood 2.5.5-2
CentOS release 6.7
kernel - 2.6.32-573.8.1.el6.x86_64
4PB Lustre Filesystem
Robin Hood Host has 2TB RAM and 390GB Disk capacity
FDR Infiniband fabric network
A Failover setup on all lustre servers

  After installing robinhood , I have faced a challenge when I kickstart 
a scan. For some reason the RBH host reboots just a few seconds after 
issuing the scan command. I have traced the robinhood logs but they give 
the following:

2017/06/08 16:19:38 [15616/21] FS_Scan | openat failed on 
23/pci-0000:00:1a.0-usb-0:1.6.1:1.2-event-mouse: Too many levels of 
symbolic links

As a test i started the robinhood-lhsm service and it started fine 
without the initial scan.
The command - rbh-lhsm-report --fs-info gives you some info but not much 
detailed.
The command - rbh-lhsm-report -a says file storage has never been 
checked which means a scan is needed.
Currently the filesystem is in production. Can this the main reason why 
it crashes.
The filesystem is sitting at 2.6PB of used capacity.
