Hi Rolandas,
thanks for your notes.
Points 1 & 2 were addressed in the latest security release. Point 4 is also changed.
Point 5: Hard to say without inspection why mariaDB wouldn't start automatically.
Concerning point 6: We will eventually improve on the Grafana Home dashboard.
Best,
Roland

Hi,
I did upgrade from Qlustar 13 to 14 successfully, but there are some notes, probably important for others.
- Before upgrade I removed HA components on Head node, we didn't use
them and they created problems with "apt dist-upgrade" on test cluster.
- LDAP server warning
olcPasswordHash: value #0: setting password scheme in the global entry is deprecated. The server may refuse to start if it is provided by a loadable module, please move it to the frontend database instead
could be solved with
ldapmodify -c -H ldapi:/// <<EOF dn: cn=config changetype: modify delete: olcPasswordHash
dn: olcDatabase={-1}frontend,cn=config changetype: modify add: olcPasswordHash olcPasswordHash: {CRYPT}
EOF
- Missing backup-qlustar-db
/bin/sh: 1: /usr/share/qlustar/exec/backup-qlustar-db: not found
could be solved by commenting line in /etc/cron.d/qluman-server
- Prometheus/grafana works OK after suggestion to add boot config
implicitly (for e.g. default).
- In docs at
https://docs.qlustar.com/Qlustar/14/ClusterOS/release-notes.html#_update_ins... it is suggested to run
cp -a /etc /var/backups/etc-qlustar-14
when it is better to name backups on version it was run so
cp -a /etc /var/backups/etc-qlustar-13
I had to change /etc/default/slurmdbd and other old config files to silent some warnings in new version.
- When running step 9. of update I found mariaDB not running, so I
had it start manually (in qlustar-post-update.sh I let remove old qlustar 13 components).
- In grafana I still missing the way to see all compute nodes in one
page as in ganglia, of cause it doesn't scale to bigger number of nodes and probably could be made with custom grafana configuration. Also I didn't yet find the way to allow browsing of data without authentication, but with restriction by IP addresses.
