Hi, when using multipath-tools we have for example 8 paths to same disk - dorado_{site}_{path} (4 onsite, 4 offsite). Disks are mapped under VG vg-dorado-{somename}. It's possible to disable ability to even select iscsi disk for example when migrating from storage to storage? Just to harden...

libssl3 is used in debian 12. PVE 7.4 is debian 11. Configure your zabbix repository correctly https://www.zabbix.com/download .

You can. But same version is better sometimes. If you use HA, you will have problem with quorum with 4 nodes.

Multiple virtual network interfaces, every with own tag. https://pve.proxmox.com/wiki/Network_Configuration

Hi, i followed pve documentation on upgrading ceph pacific to quincy, so, full upgrade to last pve 7, reboot, change to quincy, upgrade, restart mons/mgrs/osds, all went ok. But after this i rebooted one upgraded host and osds doesn't come up: Jul 11 02:31:03 proxmox-03 systemd[1]: Starting...

It depends. Everytime you will need something from slower node, your faster node will wait. On smaller cluster it will be more visible than on bigger. Anyway, using 15k 600GBs disks is performance hit anyway for ceph no matter if they are old or new - performance is the same usually if on the...

https://pve.proxmox.com/wiki/Open_vSwitch Create OVSIntPort for PVE and connect it to bridge.

You can read and try https://grok.lsu.edu/article.aspx?articleid=16716 or google more around it.

Debian 10 is old, so documentation is probably little outdated in that section.

Local storage can be per the node no matter if the node is part of cluster or standalone. For pve it's just right configuration in datastore->storage.

What you want? Block or file storage on such raid?

After tests with dedicated network card i am able to get multipath only with dedicated subnets no matter if via openvswitch/lacp or dedicated card without any lacp. Marking as solved for now.

I can disable it so i will look into it.

We don't have experience with iscsi, so we don't know some things yet. So: 1] is LACP problem? We don't have dedicated 10G cards for iscsi on PVE hosts now 2] if we switch from single to multiple subnets, will be 1] ok or will we need to be without LACP? 3] will multiple subnets require...

Hi, we are testing our new iscsi storage. Based on proxmox iscsi documentation we have now: root@proxmox-mon-01:/etc/network# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 279.4G 0 disk |-sda1...

Ansible is calling apt modules (https://docs.ansible.com/ansible/latest/collections/ansible/builtin/apt_module.html ) for update installed packages. The problem isn't tied to ansible, it shows even on manual update.
