[Qlustar-General] Can't install

Hi, I have a small collection of Skylake HP desktops I'm deploying Qlustar onto as a lab environment. I cannot get the system to boot correctly. I'm using the Windows utility "Rufus" to image the USB stick. If I use "dd" mode, when I try to boot it skips right over it as though it weren't bootable. If I use "iso" mode, it gets about six seconds into the boot process, loading modules, before it complains it can't load the vfat module. It is indeed not in /lib! I feel like I must be doing something wrong here, but damned if I can figure it out solo. I have also tried this on a Mac and on a Linux machine with BalenaEtcher; same results as "iso" mode on Rufus. Hope everyone is having a good weekend! Jarett

[Qlustar-General] Qlustar Feature Update 12/19
by Roland Fehrenbacher 09 Dec '19

09 Dec '19

A number of new Qlustar features were completed recently and published together with the latest security updates. QluMan has the following new capabilities: * RXEngine command output is searchable now [1], making the analysis of command results a lot easier. * RXEngine Command History management [2] has been improved to allow for fine-grained control during removal of unwanted entries. * Cluster logging as displayed in the QluMan Log Viewer [3] has been vastly enhanced: + New message categories have been added for managing chroots, start/stopping of slurmd and RXEngine executions in general. + Messages originating from node reboots have been merged into single summary entries to hugely reduce the number of messages and better track cluster state changes. * The QluMan GUI now checks for version updates when starting up [4]. If you use QluMan singularity images, make sure you download [5] the latest version. In addition, we have integrated the latest OpenHPC 1.3.9 release, so a big pile of updated packages are available for those of you running CentOS/OpenHPC.

[Qlustar-General] Error: No such user: 'admin'

Dear all, I am trying to setup a new cluster using the current 11.0.0-3-image. I have tried already several times (also with updated image) and usually the setup works fine. However, when trying to create the token, I keep getting the error qluman-cli --gencert ERROR:client.cli.network:client.cli.network.Cluster.__init__(): could not connect to server Error: No such user: 'admin' ERROR:qlunet.Node:Channel[('zmq_version_info', 1)].do_recv(): exception in request generator Traceback (most recent call last): File "/usr/lib/python3/dist-packages/qluman-11/qluman-cli.py", line 1331, in gencert db.users.lookup(field="name", val=user) File "/usr/lib/python3/dist-packages/qluman-11/common/types.py", line 1866, in lookup raise KeyError KeyError During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/qlunet/Node.py", line 141, in do_recv args = next(self._generator) File "/usr/lib/python3/dist-packages/qluman-11/qluman-cli.py", line 1334, in gencert sys.exit(1) SystemExit: 1 ' /var/log/qlustar-initial-config.log ' does not contain any errors or suspiciously-looking parts and everything went through on the first trial. Thus I went out of own ideas about what could cause the problem. Many thanks in advance, Tobias Moehle
