I have a cluster of some machines, each having two bonded interfaces (and, luckily, a simple dedicated maintenance interface). After dist-upgrading from 8.0.4 to 8.1.4, which upgrades also ifupdown to ifupdown2, the bonded interface get disabled immediately after enabling bonding, disabling all...

Unsere PVE-Hosts laufen mit Linux 5.15.104-1-pve und 7.4. Demnächst steht der Upgrade an. Natürlicherweise wird dazu jeweils ein Host evakuiert, alle VMs per Live-Migration auf andere Hosts verteilt. Das hatte allerdings beim letzten Upgrade zu allerlei Streß geführt, viele VMs waren nach der...

Meine Server haben RAID6 mit Journal, und haben ab und zu mal "task xxx blocked for more than 120 seconds" Probleme. Der Patch unter [PATCH AUTOSEL 5.15 28/47] md/raid5: Wait for MD_SB_CHANGE_PENDING in raid5d scheint mir genau das Problem zu fixen. Der Patch fließt wohl in alle LTS-Kernel ein...

Seit mein Cluster auf 7.2 ist, passiert es ab und zu daß in VMs Zeitsprünge auftreten, stets in Zusammenhang mit Migrationen aufgetreten (nicht unbedingt der betroffenen Maschine selber). Beim jüngsten Fall ist der Zeitsprung passiert, während eine andere VM neu gestartet wurde, daher denke ich...

Today, I live-migrated several VMs away from a PVE 7.1 to a 7.2 machine (shared storage). Most VMs behaved fine, but two showed a strange issue and needed reboot (all VMs 4.19 kernel, NTP synced using systemd-timesyncd). Migration took place at 11:25, took a few seconds with no problems...

In a cluster of PVE 7.0 machines, I observe that machines have much less free memory than expected. I evacuated one machine, and rebooted. After the reboot, free shows 8GB used of 32GB total. 24h later, the RAM used has increased to 12GB. I can't locate any responsible process for this: htop...

Running pve7 on a Supermicro board with Intel C3758, ECC memory, on-board NIC, 2xSamsung 860 pro. No problems with memory, temperature or SMART status detected, load is constantly low. Two VMS running, one OpnSense firewall, one Debian helper VM. pve has been rebooting 5x in the last 5 days...

I've setup LVM with lvmlockd and sanlock, backed by iscsi storage via multipath. AFAICS multipath can't be configured via GUI, so the actual backing of the volume group is unknown to PVE which should be fine since multipathd will handle everything. storage.cfg looks like this: lvm: santest...
