Hey all, I'm sure a few of you have seen the plugin we are developing over Reddit, but I wanted to make a formal post on the forum here to hopefully get more testers and feedback.
The plugin, source code, and documentation is all available here...
Sorry for resurrecting a very old post, but it took me forever to find the solution to my problem, which was very similar, and this one keeps coming up in search results.
I had two interfaces in my host on the same network, and apparently, in...
Hi,
Du hast als Directory den Pfad /dev/sda eingetragen. Das ist zwar der Pfad zum Gerät, aber so funktioniert der Zugriff nicht.
Du musst die Partition auf dem Gerät erst einbinden. Das geht in der Shell, in etwa so:
mkdir /mnt/sda1
mount...
Ceph on only three nodes may have some disadvantages. My own journey to Ceph ended here: https://forum.proxmox.com/threads/fabu-can-i-use-ceph-in-a-_very_-small-cluster.159671/
How fast is your network? Did you use "good" SSDs for the OSDs?
Hi highliter,
wie oben gesagt, für Details sind eigentlich mehr Infos nötig.
Aber zu 95% würde ich schätzen das Falk dir scho ndie passende Lösung geschrieben hat.
Wenn die ISO unten drunter aus dem Filesystem gelöscht wurde, kann der Qemu...
Dann editiere die VM Hardware und werfe das iso aus dem virtuellen CD Laufwerk.
Da brauchen wir mehr Infos, eventuell schreibst du Backups auf local? Aber das ist Glaskugel lesen.
That's not "reinstalling", that is expanding an existing cluster and then upgrading some old nodes. For me this looks like the way I would go.
For the upgrade read https://pve.proxmox.com/wiki/Upgrade_from_8_to_9 in beforehand and consult...
Hello,
Thanks for the suggestion. I was thinking of reinstalling the cluster, that is, adding the two new servers with pve9 to the cluster and moving the machines so that I could then update the four nodes of the cluster. I'm not sure if this is...
Notwendig ist es nicht, aber wenn du 100% sicher sein willst, so wie im Unternehmensumfeld nimmt man natürlich einen richtigen Server.
Ohne ECC ist jederzeit ein Bitflip möglich, sollte aber eigentlich spätestens beim Verify wieder auffallen...
Guckst du: https://de.wikipedia.org/wiki/Speichermodul#Fehlererkennung_(ECC)
ZFS treibt ziemlich viel Aufwand, um Verfälschungen in den Daten zu erkennen - mit Erfolg! Aber falls der RAM fehlerhaft arbeitet, nützt das möglicherweise nix. Darum...
Ich fahre zweigleisig, für VMs und LXCs nehme ich den ProxmoxBackupServer, für Rohdaten ein anderes Backuptool (restic in meinen Fall, aber es gibt ja viele Möglichkeiten (duplicati, rsnapshot, zfs send/receive, borg...)
VMs/LXCs:
Ich habe...
I actually found the answer myself..
So in short you need an External vote whenever you have an even number of nodes.
so i will not be setting up multiple corosyns (i. don't even think it is possible now that I have seen the configure command)
Ahem... thank you, though I need to go back and study to fully understand the retention concepts.
At least I figured out that removing keep-hourly solved the problem (what matters to me is keeping the one-off jobs I run manually during critical...
You last job is not nightly at midnight (should show 00:00 for midnight)
24:00 is same as just 24, meaning once per hour at 24 minutes after the hour (triggers 24 times per day !)
Always use the schedule simulator to verify scheduling.
You can do this: https://pve.proxmox.com/wiki/Root_Password_Reset
You can also undo anything related to SDN in /etc/network/ location.
Any locale should have a colon , you can just try all on-screen keys in user field first, so you can see what...
It may be possible that the corosync connection had a hard time to do its job on a possibly congested wire.
Please search for it, the recommendations/requirements for corosync are clear: low latency at all times + if possible have a second...
Hello,
do you happen to have your OpenE-JovianDSS on dedicated storage hardware? I have no experience with the plattform but from what I could google it supports NFS, iscsi and CIFS, they even have a doc file on it...
First question: is High Availability enabled? (Assuming you are running a cluster, which you did not tell us.)
If yes: has corosync a separate ethernet connection? How many rings are established?
If not: there are more possible reasons than I...
