I have a bond binding two nics connected to two switch ports each with an untagged and multiple tagged vlans (802.1q). On top of the bond is a bridge (linux ifupdown2 not ovs). Now I add some VMs. VMs which receive a vlan tag see only the vlan tagged traffic, all good. VMs without a vlan tag see...

I am currently testing integration of AD with PVE including syncing and found the documentation and wiki somewhat incomplete. Especially there were two points can I use bind_dn and similar with AD as well (yes) how to filter a set of users and/or groups. Luckily there are options documented in...

Since I needed to document the process anyway I thought I share my experience of migrating a domain controller from a hyper-v cluster to a proxmox cluster with ceph storage. I wrote this with these 2 wiki articles as background information...

On our nodes interfaces got renamed from predictable to old naming scheme, i.e. eno1 -> eth0, eno33p0 -> eth3 … But why? No /dev/null links in /etc/systemd/network. No net.ifnames=0 in /proc/cmdline. No … wait, why is there a /etc/systemd/network/99-default.link file. That is new. Contents: #...

Just discovered the PBS Prune Simulator while looking at the pve documentation, really nice. Maybe add the option to create not only scheduled backups but also adhoc backups? That would help to visualize the scenario mentioned in the pve-docu:

Maybe hardware specific, with kernel pve-5.11 some Mellanox ConnectX-5 cards (onboard and pci) changed their names, which obviously caused havoc on our network config. What does it say on Predictable Network Interface Names again? > Stable interface names when kernels or drivers are...

I noticed something strange recently. If I bring a slave interface of a bond with mode 802.3ad down, the bond loses network connectivity for about 70-80s. If I unplug the cable I lose connectivity for less than one second (2 lost pings when intervalis 0.1s) which is what I would expect. I can...

I have a cifs storage configured in storage.cfg that points to a dfs path. I just noticed that this stopped working. Going back in /var/log/messages* it correlates to the upgrade to pve-kernel-5.4.101-1-pve on 2021-03-02. The same dfs mount still works on my client machine which is still on...

Hi, I am running a proxmox 5.3 cluster with ceph storage (5 x Dell 720xd, each with 12 x 4 TB spinners, 2 DC S3700 for WAL and DB, 2 x 10 Gb ovs-slb-balance) and experience poor read performance in the vms (~50 MB/s sequential read), write performance is fine (1xx-2xx MB/s). I see similar...

Hi, when changing the ceph monitors via the web gui in our proxmox cluster I noticed that the settings in /etc/pve/storage.cfg did not update, while the ones in /etc/pve/ceph.cfg did. This led to the situation that VMs could not be started (and migrated online) anymore, as the -drive parameter...

Hi, I ran into a problem yesterday when adding osds to a ceph cluster using pveceph createosd. pveceph reported success, but running ceph-deploy disk list listed the osds as unprepared, ceph-osd services were not running and /var/lib/ceph/osd was empty. ceph-disk zap, a simple wipefs, zeroing...
