Can you find these entries in your filesystem and see what are their
type: symlink, char/block device, ...?
As you host crashes, maybe some syscall made by robinhood to the lustre
client wouldn't properly handle this kind of entry.

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

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.
