Denied permission when restoring a database in qluman-qt
by ldettmann＠web.de 25 Feb '25

25 Feb '25

Qlustar version: 13.2 Qluman version: 13.7.2 I am trying to restore a qluman database from another server using "Manage Cluster" > "Global Configs" > "Restore database" and encountered an error: Permission denied. However, I also tried it with a backup, which I created within the current session, and encountered the same error. What can I do? Best regards, Lorenz

QluMan configuration for single sign on
by João Manuel Rodrigues 19 Feb '25

19 Feb '25

Documentation says: "b) QluMan may be configured to allow for a single sign-on setup where users can be imported from and authenticated against an Active Directory (AD) server." <https://docs.qlustar.com/Qlustar/13/ClusterOS/qluman-guide/components/ldap.…> How can I configure QluMan this way? I have configured sssd on the head node to connect to our AD (ldap + kerberos), but in QluMan, "Components > LDAP > Import Users > From AD" is disabled (gray). Thanks, João

BeeFGS setup help
by aninramesh＠gmail.com 25 Jan '25

25 Jan '25

Hello, I'm currently attempting to establish a BeeFGS file system on qlustar. Thus far, I've been following the qlustar documentation to assist with the setup process. However, I've encountered a problem following the step "+ Their beegfs role is assigned to the nodes in /etc/qlustar/common/image-files/softgroups. Change the node names there according to your naming scheme," that is found in the [BeeGFS on Qlustar - Quick Start] https://docs.qlustar.com/Qlustar/13/DataStack/quick-start-guide.html. Despite integrating the client and server name in accordance with my qlustar setup, the mount point does not appear on the client side. I attempted to restart the nodes, but this was unsuccessful. Is it possible for you to provide some guidance on this issue? I also want to point out that an error occurs when I input the `beegfs-ctl` command on the storage node. Even though the configuration file indicates that connDisableAuthentication is set to true, the error message states, "Unrecoverable error: No connAuthFile configured. Using BeeGFS without connection authentication is considered insecure and is not recommended. If you really want or need to run BeeGFS without connection authentication, please set connDisableAuthentication to true." I have also made an attempt to mount a drive via the 'Network FS Mounts' dialogue box in Qluman, but to no avail. I followed the instructions provided in section 7.5 - Network Filesystem Exports/Mounts. I welcome any suggestions or thoughts you may have on this issue. Additionally, I believe I have identified an error in the `https://docs.qlustar.com/Qlustar/13/DataStack/quick-start-guide.html`. Within section 1.2.1 (Create storage server instance), isn’t the command `beegfs-setup-storage -p /beegfs/stor -s ${HOSTNAME##-} -i ${HOSTNAME##*-}01 -m beosrv-c` as opposed to `beegfs-setup-storage -p /beegfs/stor -s ${HOSTNAME##*-} -i ${HOSTNAME##*-}01 -m beosrv-c`?

MD5 and SHA256 hashes for the QluMan 12.0.7.5 Singularity image don't match those shown in the Download page
by Beethoven Santos 30 Nov '24

30 Nov '24

Hi, Whenever I download the file `qluman-12.0.7.5-singularity.sqsh` and use the `md5sum` and `sha256sum` commands to check its MD5 and SHA256 hashes, I find that they do not match the hash values shown on the [Download page](https://qlustar.com/download/) for this version (all others are ok). For this reason, I believe that using this file is not safe and I should avoid it. Is this something on Qlustar's side? Could anyone confirm this issue? Best B. Santos
