Hi, i have debian 11 VM as golden image. I have boot disk set as /dev/sda. VM shutdown, cloud-init disk regenerated. Disk /dev/sda: Disk /dev/sda: 10 GiB, 10737418240 bytes, 20971520 sectors Disk model: QEMU HARDDISK Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512...

Yep, the pve classic and special "flush browser cache after pve upgrade" problem as usually... Console works.

Restored VM backup from pve-manager/7.3-3/c3928077 (running kernel: 5.15.74-1-pve) to pve-manager/7.4-3/9002ab8a (running kernel: 5.15.102-1-pve) noVNC console doesn't work. VM is debian 11, VM is up and pingable. Mar 31 10:40:04 proxmox-mon-01 pvedaemon[158819]: starting vnc proxy...

Doesn't help. It's even more crazy. Old 17" monitors are "Out of range", "No input supported", full HD same. Everything stops working after grub selection and before EULA screen. PVE 7.1-2 iso works without hiccup.

Nope, doesn't help.

Mounted proxmox-ve_7.4-1.iso as image file via ILO Integrated Remote Console on HP DL360 G7. Impossible to use installer: The first screen with boot menu selection is 1024x768, but in initializaton phase screen switch to 640x480. Any way to stay in 1024x768 at least? Or the only way is...

Service networking was set disabled dunno why, when PVE updated. Solved

Second Q: both links are DAC 10G sfp+ cables. One is up, second is still down even after 30m. It was hours after last reboot (month ago), before down link changed to up. I reconnectedboth cables on server side yesterday (forgot on the switch side). Bad cable? Some dwarf?

Hi, server has ens1f* interfaces down after PVE reboot. Both interfaces are bonded and used via openvswitch-switch. The first half shows ens1f* down and one VM starting (tap10110). The second half shows both links still down and VM failed to start, so tap iface is removed. All bond/OVS...

osd_pool_default_min_size = 2 osd_pool_default_size = 3 Calculate. You have 4 nodes with osds and for example 1 pool. Host replication (i think it's default). You have 3 copies and need 2 copies to have cluster working. What will happen, when you shutdown specific nodes holding those 2...

Isn't tls1/1.1 disabled anyway? Because PVE7.2 is based on Deb11 and it's openssl.conf has set MinProtocol = TLSv1.2 Hmm, it looks, postfix doesn't honor openssl configuration. SOMEHOST:~$ openssl s_client -connect PMG:25 -tls1 CONNECTED(00000003) 140408873498256:error:1408F10B:SSL...

What? Any link? Doesn't pvesm depends on v3?

Ah, so email = recipient, Adddress = blacklisted sender. So, just not much helpful UI.

Hi, we added email to Administration->User Blacklist: But email is still delivered: Sep 29 12:52:34 pmg-01 pmg-smtp-filter[1815039]: 401A7633578ECED94F: SA score=1/5 time=5.279 bayes=0.00 autolearn=no autolearn_force=no...

Hm, 100GBit/s switch...show me please switch with almost 1Tbps ports.

FYI - this problem is not only PVE side, because last night maintenance it hit (semirandomly) about 5% VMs.

Opteron 6276 is very old and slow performant. Use better HW. Problem solved.

Hypervisor with 1 disk is nonsense if you don't have multiple such hypervisors with network storage. Solution: 2x ssd raid (pve+vm/cs) + hdd raid as data/backup storage only or 2x ssd raid (pve) + 2x ssd raid (vm/ct) etc.
