ood-appsrole that stays output-compatible across OSes and airgap. - A new Rack GUI application (aligned with the AlertX GUI) and SSL certificate-key support for OOD.
Airgapped installations
Covering TRIX-1625, TRIX-1772, TRIX-1773, TRIX-1877, TRIX-838
- End-to-end airgap support: per-distribution local repository handling (ELRepo, RHEL, EPEL, pacemaker, pip), and airgap-ready OOD core, OOD apps and Rack.
- Luna and DHCP coexistence under airgap (letting luna2-daemon own DHCP to avoid race conditions) and a dedicated cv-slurm repository configuration for airgapped installs.
TrinityX Slurm & OpenHPC deprecation
Covering TRIX-1609, TRIX-1608, TRIX-1644, TRIX-1613, TRIX-1645
- Introduction of TrinityX Slurm (cv-slurm / trx-slurm) with its own repositories, slimmed package sets for images, relocated
pdsh(cv-pdsh) role, and a systemd drop-in for theslurmdoverride. - Slurm resource constraints by default:
pam_slurm_adopt(cgroup/ssh-session confinement) and memory constraints. OpenHPC is deprecated in general.
Monitoring & AlertX
Covering TRIX-1287, TRIX-1284, TRIX-1721, TRIX-1692, TRIX-1889
- New
alertx_historydaemon persisting alert state changes to MariaDB, surfaced through a dedicated Grafana "Alert History" dashboard, with HA-aware history handling. - New ECC alert rules and optimised scrape intervals. Prometheus, Alertmanager, OOD and Grafana service ports are now closed by default (manual override to open).
Distribution support: EL10, DS389 & OOD 4.1
Covering TRIX-1518, TRIX-1561, TRIX-1822, TRIX-1861, TRIX-983, TRIX-1859, TRIX-1604
- OOD bumped to 4.1.1 (reverted to 4.0 on EL8, which 4.1 does not support), EasyBuild EL10 workarounds, and

resolv.confand corrected BIND paths.
Install hardening, migration & credential safety
Covering TRIX-1681, TRIX-1580, TRIX-1581, TRIX-1623, TRIX-1657, TRIX-1658, TRIX-1663, TRIX-1809, TRIX-1865, TRIX-1839, TRIX-1872, TRIX-1884, TRIX-1890, TRIX-1870
- Migration utility for
all.yml, configurable temp directory, newer ansible-core compatibility, faster repeat package installs, and a controller auto-upgrade block. - Safety gates that halt installs on default Luna or BMC passwords, an unusual umask, or unexpected controller hostnames (all overridable). A Luna secrets-at-rest encryption flag and the broad Luna security audit (TRIX-1872) landed here, along with capability-based selection of the MySQL Ansible module.
Luna 2.x — networking, DHCP & iPXE
Covering TRIX-1769, TRIX-1841, TRIX-1587, TRIX-1678, TRIX-1802, TRIX-1832, TRIX-1859, TRIX-1768
- Kea DHCP(v4+v6) maturity: a
dhcp_nodes_onlymode, fixed/shared-network and pool-in-zone handling, and boolean-normalised network updates, plus group/node interface-name change support. - Configurable iPXE kernel selection (TRIX-1841): an easy per-target toggle between iPXE kernels, backed by a dedicated Kea iPXE-kernel boot class.
- DNSSEC and modern-vs-legacy BIND handling, and improved Ubuntu bonding so a
bootifinterface can safely be used as a bond member (TRIX-1832).
Luna 2.x — plugins, images, BMC & queue
Covering TRIX-1784, TRIX-1003, TRIX-1695, TRIX-1252, TRIX-1813, TRIX-1882, TRIX-1814, TRIX-1864, TRIX-1603, TRIX-1872, TRIX-1030
- Automatic plugin and template reloading and synchronisation: plugins auto-invalidate on file changes and boot plugins sync between HA controllers. Startup overhaul, with the work queue draining and requeuing on restart and workers scaled to available cores.
- Diskfull and Raid1 boot plugins extended beyond EL to Ubuntu and openSUSE (TRIX-1252): proper GRUB/shim and EFI bootloader installation (including for non-Ubuntu images), an arm64 removable-boot fallback, a fallback second EFI disk, and clean handling of pre-existing/foreign RAID members.
- BMC improvements including Dell racadm plugins and controller renumbering on HA network changes; safer remote image clone/rollback; and the TRIX-1872 daemon security audit (JWT expiry, credential redaction, optional secret encryption). luna2-cli gains
lrack/discoverbash completions (TRIX-1030).
Bug fixes & hardening

Previous 15.3u1 release
TrinityX 15.3u1 bug-fix release was published on February 20 2026. In principle no features were added but the following bugs were resolved:
- Compute and K3s image building fix for HA setups
- 389-DS installation time mismatched package for EL9
- Enhancements for RHEL based installations image creation and subscriptions
- Enhancements for playbook runs for workload manager based settings
Details
Image building
Covering TRIX-1592, TRIX-1340, TRIX-1460
- Reworked the Kubernetes/K3s playbooks so the image role is driven from the main
image-createrole, fixing compute and K3s image building on HA setups, with more robust openSUSE bootstrap and kernel-version detection.
RHEL / EL installations
Covering TRIX-1591, TRIX-1611
- Improvements to the RHEL "extend" tasks for image creation and subscriptions, and a fix so the 389-DS install completes on EL9 (mismatched package).
Playbook runs & workload manager
Covering TRIX-1593
- Logrotate handling is now delegated to each individual role rather than centralized, and a
whenconstraint was added so the Slurm parts only run where applicable.
Luna 2.x
Covering TRIX-1104
- luna2-daemon: database calls now correctly handle non-epoch date strings, and
lexportdata import was aligned with the current database tables.
Bug fixes & hardening
- Ubuntu package-mirror changes: switched the ARM mirror to
ports.ubuntu.com, and replaced the NLUUG mirror with the U-Twente mirror for more reliable package retrieval.
15.3 release
TrinityX 15.3 was released on February 4 2026. A Brief list of included enhancements and features:
- BETA EL10 support, including RedHat Enterprise 10, Rocky Linux 10 and Alma Linux 10
- Adding Kea DHCP(v4+v6) support, introducing a slow transition from depcrecated ISC dhcpd
- Adding 389-DS support to replace deprecated openldap
- Open OnDemand version 4 for images/nodes
- OpenHPC version 4 for EL10
- Any-Image to support luna osgrabbed images
- Override to restore components to defaults
- Bug fixes for HA Easybuild paths, bcrypt and others
Details
EL10 beta & distribution convergence
Covering TRIX-1453, TRIX-1340, TRIX-1338, TRIX-1009, TRIX-1155
- Introduced BETA support for the EL10 family (RHEL/Rocky/Alma 10), with dedicated EL10 variable files, OpenHPC 4, EL10-aware DRBD/shared-FS handling and an EL10-aware OOD stack.
- Converged the per-distribution logic so images build the same way across EL, Ubuntu and openSUSE: image creation was made controller-independent, and the package layer (
dnf/apt/zypper) was merged behind a singlepackageabstraction with shared, cross-distribution roles. The module environment switched to Lmod, and password hashing moved offbcryptto a passlib-based approach.
Kea DHCP (v4 + v6)
Covering TRIX-1394, TRIX-1424
- Added a Kea role as a Luna dependency, selectable via a single
luna2_use_keaflag, preferred on RL10+. Luna gained Kea DHCPv4 and DHCPv6 templates, TSIG-key support (for both Kea and bind), DHCP-DDNS logging and interface discovery for Kea DHCPv6, paving the road for alternative DHCP back-ends alongside the existing bind/named path.
389 Directory Server backend
Covering TRIX-1435
- Added a 389-DS role with full backup and HA support, a directory back-end selector, SELinux contexts, and obol scripting for DS389. The sssd, ssl-cert/CA-certificate and authselect paths were overhauled so authentication works consistently across all supported distributions, and images were taught which directory back-end is in use.
Open OnDemand 4 & native image import
Covering TRIX-1281, TRIX-1453, TRIX-1338, TRIX-1249
- Open OnDemand updated to version 4 for images and nodes, with configurable Shell-app inactivity and maximum-duration timeouts and DS389 awareness. Added native TrinityX import of osgrabbed ("Any-Image") images, with a distribution fallback (EL only for now) when the image distribution is not supplied.
Override / restore-to-defaults
Covering TRIX-1109
- Added an override mechanism to reinitialise components back to a known-good default state, covering Slurm, openldap/Luna re-init and SSL-cert regeneration.
Luna 2.x
Covering TRIX-1424, TRIX-1426, TRIX-1523, TRIX-1524, TRIX-1425, TRIX-1467, TRIX-905, TRIX-1419, TRIX-1478, TRIX-1477
- luna2-daemon: Kea DHCPv4/v6 templating and TSIG support (TRIX-1424); full by-UUID
fstabsupport for the diskfull and raid1 boot scripts (TRIX-1426); reduced startup overhead by trimming unnecessary named/DHCP config rewrites and network-plugin loads (TRIX-1523, TRIX-1524); correct IPv4/IPv6 handling when switching node-interface networks and VLAN-on-bond templates (TRIX-1425, TRIX-1467); input validation for provisioning method, scripts and roles (TRIX-905); a bulk hook plugin that reconfigures Slurm (TRIX-1419); and a fix for clearing VLAN/bond settings (TRIX-1478). - luna2-cli: fixes to correctly clear bond mode/slaves and VLAN/parent on nodes and groups (TRIX-1477).
Bug fixes & hardening
Covering TRIX-1448, TRIX-1513, TRIX-1401, TRIX-1259, TRIX-680, TRIX-1358, TRIX-1357, TRIX-1337
- Fixed the EasyBuild mountpoint/install on passive HA controllers and the OHPC/EasyBuild mount order (TRIX-1448, TRIX-1513); renamed
slurm-gres.conftogres.conf(TRIX-1401); scoped the InfiniBand exporter to controllers/IB-connected servers only and added drain/undrain sudoers for the IB analyzer (TRIX-1259, TRIX-680); fixedtrix_rootandslurm.confparameters (TRIX-1358, TRIX-1357) and a PJS GPU-usage panel bug (TRIX-1337). Numerous fixes were folded in across iPXE downloads (now using a CV-hosted location), elrepo base URLs, MOTD/logo refreshes and Ansible boolean-compatibility cleanups.

- Luna daemon HA journal/replication and a substantially extended luna2-cli
Details
High Availability
Covering TRIX-393

- Introduced an NVIDIA exporter role and fixed several existing exporters, added an
allowed_exportersdirective, and improved the Prometheusfile_sdrole and target discovery (by IP, all controllers). - A broad Grafana refresh — reworked home dashboard, navigation bar across dashboards, and consistent refresh intervals — with Slurm updated to match the new monitoring.
Open OnDemand
Covering TRIX-148, TRIX-253, TRIX-265, TRIX-282, TRIX-285, TRIX-295

Identity, authentication & security
Covering TRIX-175, TRIX-230, TRIX-249, TRIX-398, TRIX-407, TRIX-412, TRIX-413, TRIX-260, TRIX-390
obolfeature updates with added logging, relocation to/usr/local/sbin, and authentication-tag fixes (including external-auth admin-group handling).- Install-time hardening:
luna.dbset to0600, and installation halts if SELinux is disabled (requiring a reboot).
Image building & provisioning
Covering TRIX-247, TRIX-315, TRIX-336, TRIX-338, TRIX-378, TRIX-395, TRIX-439
