Robin Hood Installation fail to scan on Lustre IEEL v2.5
by 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
2017/06/08 16:19:38 [15616/21] FS_Scan | openat failed on
23/platform-pcspkr-event-spkr: 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.
