[Qlustar-General] Unable to generate one-time token
by Ansgar Esztermann-Kirchner 24 May '18

Hello List, after installing Qlustar 10, I've tried to connect to the cluster via the GUI. However, I am unable to generate the necessary token: # qluman-cli --gencert -o cert ERROR:client.cli.network:client.cli.network.Cluster.__init__(): could not connect to server Error: No such user: 'admin' ERROR:qlunet4.Node:Channel[('zmq_version_info', 1)].do_recv(): exception in request generator Traceback (most recent call last): File "/usr/lib/python3/dist-packages/qluman-10/qluman-cli.py", line 1274, in gencert db.users.lookup(field="name", val=user) File "/usr/lib/python3/dist-packages/qluman-10/common/types.py", line 1678, in lookup raise KeyError KeyError Checking the logs, there seems to be something wrong with qlumand and/or its database (see below). Any ideas? Thanks a lot, A. syslog excerpt: May 9 15:03:52 cl-head systemd[1]: qluman-server.service: Service hold-off time over, scheduling restart.

[Qlustar-General] PXE boot
by Bob Johnson 02 May '18

02 May '18

The nodes will not PXE boot. I see the standard install loads the Realtek r8169 driver. Based on past experience, my hardware requires the r8168 driver. Can the NIC driver be changed in qlustar? Do I execute the following commands at the root@cl-head~# prompt. Or from a different location? apt-get install r8168 -dkms rmmod r8169 lspci -s 3:00.0 -vv (verifies the r8168 driver is loaded) reboot thanks

by Bob Johnson 23 Apr '18

Reviewing my notes from a few years ago, it appears that I am having some of the same issues with loading Slurm and creating a chroot file during the FAI install Do I need to preload anything before the Qlustar install? Thanks

[Qlustar-General] Qlustar 10.0 install issues
by Bob Johnson 23 Apr '18

23 Apr '18

Having a few issues during the initial install of Qlustar. - Started with a clean install of Qlustar. - All was going well and then the error "failed to start rng-tools.service." - The installed continued on its own to the "Welcome to Qlustar 10..... " screen. - At the root@cl-head~# prompt I entered /usr/sbin/qlustar-inital-config command. - Next error message encountered was during the gluman bootstrap - couldn't determine IP address.... Install continued to the configure slurmbd section - Entered my slurm password twice and and I receive this error after several minutes of waiting - "sacctmgr: Can't connect do slurmbd - exiting" Any thoughts?
