UdoB reacted to Kosh's post in the thread Problems after upgrading the cluster from 8 to 9 with
Like.
Thanks, everything was resolved by updating to pve-manager/9.0.10 my nerves are saved :) -
Hallo @bertige_berti, @Falk R. hat dir bereits die entscheidenden Hinweise gegeben. Das Problem ist, dass du versuchst, ein Verzeichnis, das bereits vzdump-Backups (.tar.zst-Dateien) enthält, als PBS-Datastore zu verwenden. Ein PBS-Datastore...

In the case of power loss there is no way to live migrate the VM's RAM to a new host. In the case of fence that host has lost communication to the cluster so there is no way to migrate the VM's RAM to a new host. The question left is if one...

UdoB replied to the thread HA starts VM after proper shutdown.There is no state it can inherited. It can only start; it can only boot to then be running again. If a host is dead the VM is too ;-)

UdoB replied to the thread HA starts VM after proper shutdown.That question makes no sense. When a host is powered off a live migration is simply not possible. Live migration requires the source VM to be running! ;-)

UdoB replied to the thread [SOLVED] QDevice Deployment.I believe this is a myth :-) Let's take a look. I've added a QDev to a four node virtual test-cluster. Normal operation: ~# pvecm status Cluster information ------------------- Name: pn2 Config Version: 5 Transport: knet...

UdoB replied to the thread ZFS Config Help for Proxmox Backup Server (PBS) - 22x 16TB HDDs (RAIDZ2 vs. dRAID2).The SLOG will only help with SYNC writes. As far as I know PBS .chunks are written "normal". (Can someone prove me wrong?) And that SLOG will accept incoming data of one single 5 seconds interval while a second TXG (transaction group) is being...

Running in VM will work, but on the Host itself will see conflicts and complications.

UdoB reacted to Johannes S's post in the thread Security: recommendations for going prod with pve with Like.
There are also now Proxmox Partners who offer PBS as a managed cloud service, e.G. tuxis.nl in the netherlands or Inett in Germany. I would expect that other partners (like the ones in North America) would offer something similiar. Their pricing...

UdoB replied to the thread Set up ZPool, Replication, and HA - no snapshots. Grand total of less than 10TB worth of data. 32TB STZ reporting full, io-fault on a VM???.I'm not sure what this is. Maybe RaidZ3? You may show zpool status to show topology information. (Preferable in text form and in ...-tags.) RaidZ/Z2/Z3 can be tricky and may seem to waste a large amount of space. Example...

UdoB replied to the thread Node being offline out of a sudden - how to investigate.There are too many options without additional information. Feel free to add some more technical details regarding your system. (Cluster? Server hardware? Mini-PC? Amount of Ram? ECC Ram? HDD? SSD? ZFS? Number of VMs? PCI-passthrough? ... ... ...

Wofür willst du denn die HDDs verwenden? Als Datengrab (auch für VMs und lxcs)? Dann ist RAIDZ ok. Wenn du dagegen VMs (also deren Betriebssystem und Serverdienste) darüber laufen willst, solltest du dir das noch mal überlegen, RAIDZ ist schon...

Und bei der Schätzung des Speicherbedarf auch an 2 GByte für Proxmox VE selbst denken. Ich setze rund 1 GByte Ram für 1TB an Datenspeicher an. Mehr geht immer. Und je nach Speichertyp bitte ein zfs quota von ca. 80 % auf den gesamten Pool...

UdoB replied to the thread Wie viel RAM für Proxmox ZFS RAID.Ja, bei weitem. https://pve.proxmox.com/wiki/ZFS_on_Linux#sysadmin_zfs_limit_memory_usage : " ... will be set to 10 % of the installed physical memory," - also vielleicht etwas über 3 GiB.

I wouldn't trust any production data on something, some guy on youtube claimed to work. I also wouldn't trust anything somebody on a forum said who doesn't have his own experience but just repeat something from youtube. I wasn't talking about...

Hi! What exact error message do you get for the failed backups? Anything of interest in the PVE task log or the corresponding PBS backup task log? We discovered an issue leading to possible deadlocks. A fix is work in progress, please subscribe...

Did you consider to setup replication/clustering on the database Level?

An import consideration is the needed capacity ( rule of thumb is 0.02-0.03 of HDD storage capacity ) and amount of ssds since the redundant of the special device should match the redundancy of the pool: See also...
