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 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-mouse: Too many levels of symbolic links 2017/06/08 16:19:38 [15616/21] FS_Scan | openat failed on 23/pci-0000:00:1a.0-usb-0:1.2:1.0-event-mouse: Too many levels of symbolic links 2017/06/08 16:19:38 [15616/21] FS_Scan | openat failed on 23/pci-0000:00:1a.0-usb-0:1.6.1:1.1-mouse: Too many levels of symbolic links 2017/06/08 16:19:38 [15616/21] FS_Scan | openat failed on 23/pci-0000:00:1a.0-usb-0:1.5.1:1.1-event: 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.
