  1. [SOLVED] Proxmox VE 6 - OVH - IP failover

    Sorry guys to enter here to disturb, but that configuration above screams vengeance! It's overly complicated and unnecessary. I'll show an alternative configuration I think is cleaner and makes to easier transition from one ovh server to another. Here it goes: 1. The proxmox server only needs 1...
  2. CPU usage metrics in external metrics server not reported

    I tried with $value = sprintf '%.2g',$value; in hope that if would remove the trailing '.0' from the value when the value is integer, but no go. The problem here is semantic: You should not push a float for uptime. it is an integer. I'm logging many hosts in the system table, not only proxmox...
  3. ZFS issue receving on encrypted data set

    There seems to be an issue with the current ZFS driver. Receiving on encrypted datasets seems to trigger a null pointer dereference and a lockup that requires hard reset of the node. https://github.com/openzfs/zfs/issues/11679 My proxmox servers are affected. It seems there's a data...
  4. Cannot move subvol-based CT(s) from zfs or local storage to ceph rbd or nfs

    after some debugging, I found that the "move" routines in proxmox make use of the refquota parameter in the zfs subvol and not of the size of the disk in the ctx conf file. if the refquota is "none" as in unlimited space, this is interpreted as 0 quota. the rbd device is created with 0 size the...
  5. Cannot move subvol-based CT(s) from zfs or local storage to ceph rbd or nfs

    Update: I can confirm that subvol-based CT either on zfs-native filesystems or local storage (directory) filesystem (backed by zfs in my case) cannot have their rootfs moved to either ceph rbd or nfs backed storage. The issue seems to be that the size of the disk is determined as 0. The...
  6. Cannot move subvol-based CT(s) from zfs or local storage to ceph rbd or nfs

    A small update: So far, the only difference I found between the CT that can migrate and those who can't is that the onces that can are stored as "RAW" images, while those who can't are stored as "subvol". There's also an issue when moving disks from subvol local storage to zfs local storage...
  7. Cannot move subvol-based CT(s) from zfs or local storage to ceph rbd or nfs

    I'm having issues moving CT root fs from local storage (zfs) to ceph rbd. The problem only occurs on existing CT, created some time ago. At that time I was using proxmox 4.x The error does not occur on new CT created with proxmox 6.2, using ubuntu 20.x template. EDIT: It seems the issue is due...
  8. redundant separate 10GBit network

    Thank you. I was under the false assumption that you cannot enslave a vlan interface (as was the case some years ago). I was not able to replicate your setup and confirm it works nicely accross multiple switches for speed and as a failover if a whole switch dies. Further, connecting the...
  9. redundant separate 10GBit network

    Would you share your /etc/network/interfaces configuration ? If I understand exactly, you managed to bond the two links like this: Active-Backup - bond0 Backup-Active - bond1 Then, on a switch failure (say the second switch), they become : Active-Backup - bond0 Active-Backup - bond1 At the...
  10. MFsys25 was nice. What next?

    Hi all, I once used an Intel Modular Server (MFSYS) in one of my deployments of proxmox (1.5!) and that was a nice little blade setup. That system is now 8 years old (running the latest proxmox 5) but needs replacement. Is there a similar blade setup to be bought today ? I fail to find a...
  11. Server DOS (huge load) on container disk full

    Hello, I'm experiencing a problem caused by disk quota exhaustion on a container. Simply put, when the quota is reached inside a container, further writes are be blocked, however, the writing process is not terminated but hangs indefinitely. When this happens, the load average on the physical...
  12. Cluster fails to restart/recover after network disconection

    Hi, I have a few proxmox nodes running in a cluster, with the cluster on a separate network interface. If a cluster node looses connection to this interface temporarily (like when a cable is disconnected and reconnected), the node will never see the other nodes until reboot. I tried issuing...
  13. [LXC Stability] Cached memory leaks (killing processes (wtf!))

    Here's the bug report: https://bugzilla.proxmox.com/show_bug.cgi?id=946
  14. [LXC Stability] Cached memory leaks (killing processes (wtf!))

    Dietmar. I agree, when working properly. However, something is leaking memory with LXC containers and they become memory starved. This never occured on the *SAME* containers when they were running under OpenVZ. They would run for excess of 6 months at a time with some of then not being reboot...
  15. [LXC Stability] Cached memory leaks (killing processes (wtf!))

    I am having stability issues with LXC containers after migration from OpenVZ What happens is that when the memory is all used in a container, the OOM kicks in and kills processes (see attached example). If I try to restart a killed process it will usually fail. A reboot of the container is...
  16. [SOLVED] PVE suddunly stopped working, all CTs unrecheable

    Fabian, you might be interested to know that I've had no issues for some days now. The servers running 4.2.6+lxcfs pve2 are solid (two of them, different hardware). The ones with 4.2.8 + pve2 have been working too. jinjer.
  17. [SOLVED] PVE suddunly stopped working, all CTs unrecheable

    fabian, I think that the lxcfs was upgraded, then the containers restarted. I might be wrong tough. Now a couple of servers were downgraded to kernel 4.2.6 with an upgraded lxfs 2.0.0-pve2. There are a few other servers running 4.2.8 with lxcfs 2.0.0-pve2 so I'm waiting now. I will try to post...
  18. Proxmox 4.1 will not reboot server, kernel 4.2.8-1

    Sorry, the issue seems related to the lockup here: https://forum.proxmox.com/threads/pve-suddunly-stopped-working-all-cts-unrecheable.26458/ trying to reboot a normally working server works. Trying to reboot a server which was locked up (possibly) by lxcfs will fail. I have now reverted to...
  19. Proxmox 4.1 will not reboot server, kernel 4.2.8-1

    I'm attaching the last thing shown on the console (dmesg cannot be captured on this srv, sorry). The server (and other servers) stay on until manually reset. The other server with the same problem is a Supermicro X8DTT-H MB.
