Habe sowohl online, als auch von Kunden in letzter Zeit vermehrt die Frage gehört, was man eigentlich mit SDN machen kann, außer zentral vLAN's zu verwalten. Somit ist an einem Freitagabend dieses Setup entstanden, wo ich testen wollte, wie weit kann man die neusten SDN Features ausreizen und...

Hi, thanks a lot :)

Hi everyone, is there a "guide" on howto build/compile proxmox VE yourself? I want to tinker with the code for learning purposes :)

Das wird leider nicht so einfach. Wir haben auf das Cluster keinen durchgehenden Fernzugang und sind quasi nur auf Zuruf tätigt. Das ursprüngliche Fehlerbild sah eigentlich nach einem Storagethema aus, zumal das storage iscsi/datacore ist. Der Kunde konnte mir allerdings bestätigen, das der...

Hi, first of all, we'll need some information about you running hardware. How is the storage configurerd? Do you have a controller or hba?

Hi, wir hatten bei einem Kunden ein ähnliches Problem. Leider wissen wir bis aber heute nicht, ob es 100%tig am sophos lag. Seitdem wir die CPU auf x86-64-v4 gestellt haben, läuft alles.

I would install proxmox from scratch on the new server, would insert the hdd's and import the zfs of the hdds. Then you can copy the config files from /etc/pve/local/qemu-server to the new server. After that, every vm should be there and be able to boot

Hi, can you give us more details about the procedure you did till now?

Hi, can you give us the output of "pvecm status" ?

Technically you can create a pool for each vm and configure a replication of 1 in this pool. Then, you would have a disk per vm, but without any redundancy in the hardware/disks. In this case, it would make more sense to use zfs.

Hi, can you give us more details regarding your networking setup?

Hi, can you please give more details regarding your setup?

Hi, you have to options: You can passthough the whole card or you can create an bridge on every port and attach the bridge to the vm

Can you see an high latency for the osd's? Proxmox UI -> Ceph -> OSD

Hi, when you don't tick "Use LUNs Directly" you need to create an lvm storage on top of the iscsi Storage. This has also the advantage, the you can use it as "shared". When you use the iscsi directly, you can't use it shared

can you find any error regarding networking in the output of dmesg?

Hi, what do you expect from the "backup-Node". Do you want to run a replication or do you want to run a shard scenario where you do HA?

Hi, what is the output if you run a verify job?

Hi, regarding the CPU an RAM sizing it depends on your databases. The Network seems fine, i would size the switch redundant.

Hi, schau mal hier: https://pbs.proxmox.com/docs/notifications.html#notification-events Ich lese darauf, du musst auf dem Host nur eine Mail an root schicken, dann landet das event im Notificationsystem " System Mail Forwarding Certain local system daemons, such as <span>smartd</span>, send...
