When I upgraded remaining nodes to Jewel, the issue disappeared. Prior to this, I had one node upgraded, the remaining nodes on Hammer. I don't recall reading on the WIKI that all nodes must be at the same ceph release to create new RBD images.

Bump.. Anyone resolve this issue w/ Jewel 10.2.5?

After upgrading one of my cluster nodes to Jewel and latest / greatest apt update / distupgrade I get the following when trying to create a new VM: error writing header: (38) Function not implemented TASK ERROR: create failed - rbd create vm-7890-disk-1' error: error writing header: (38)...

Hello, recently upgraded to the latest release (4.4-5/c43015a5) + Jewel on one of my PVE notes -- still getting this error. Is there a timeline in getting this supported? "TASK ERROR: create failed - rbd create vm-100-disk-1' error: error writing header: (38) Function not implemented"

@spirit - yes I'm able to start VMs on other nodes without issues. @debi@n - I'm running identical versions across 3 nodes.. @spirit -- I just checked and I'm UNABLE to start on other nodes (offline migration successful). Had a closer look and noticed that KRBD was disabled. I enabled...

Hello, Ever since my upgrade to 4.1 and migrating my VMs to my ceph cluster, I'm noticing issues with live migration. My ceph cluster is nominal, available and operational, all nodes are able to see the rbd pool without issues. However VMs fail to migration with the following log entires...

Re: Ceph - Bad performance with small IO I was having a similar issue until recently running a PoC on Hammer. I suspect it's the SSDs not being able to keep up with direct I/O requirements Ceph has. I haven't been able to figure out how to disable direct I/O in ceph, but taking SSDs out of...

Is it possible today to present a vlan trunk interface to a KVM VM natively in ProxMox without using Openvswitch? I would like to be able to tag interfaces within the VM itself vs at the proxmox level. Thank you.

Does Proxmox 2.2 have nested KVM support? I see the KVM Hardware Virtualization under the VM options however can't see it in the KVM_Intel module: # modinfo kvm_intel filename: /lib/modules/2.6.32-16-pve/kernel/arch/x86/kvm/kvm-intel.ko license: GPL author: Qumranet...

Pretty cool script. Thanks. I filed a bug (enhancement request) already: https://bugzilla.proxmox.com/show_bug.cgi?id=262.

HI Everyone, Is there a way to invoke maintenance mode on a Proxmox cluster node? I'm looking for the semi-automated functionality of Proxmox being able to: 1. Live Migrate all running machines on a node; 2. Place this node into maintenance mode such that no new VMs can be started on that...

I'm trying eliminate the need for any hard disk storage in my Proxmox deployment (compute nodes only). Based on this URL, it appears possible to install Proxmox on a USB key and boot off it. (http://c-nergy.be/blog/?p=1159). Are there any performance impacting draw backs in doing so...

I know there are two options (type 2 = built in locking, type 3 = external locking shared library) -- any suggestions which one would work best in a Proxmox environment? For some reason when I tried to simply set the locking type (to 2) in an attempt I did last week CLVM would not start...

There's a shared option to select when specifying a volume group. Volume group curated with vgcreate (vg name) (device). I'm hoping there's a little more code behind that checkbox. Wondering I anyone can advise the best practice for lvm based shared storage in v2.0. Thanks.

Good Day, We are building a few clusters using Proxmox 2.0 RC1 (non prod evaluation / development) and are wondering what the best (and Proxmox recommended) approach is to configure SAN-storage. Based on what I've seen in Proxmox we really have a few options: 1. use LVM2 storage on shared...

What would the potential roadmap for something like OpenVswitch? Is there a preferred method of committing network changes without reboots in the interim?

The reason behind my original question is apparmor capability. I've post a separate topic on this (http://forum.proxmox.com/threads/8548-Proxmox-2-0-Apparmor-support), but if Ubuntu is not supported, is apparmor possible or supported on Proxmox?

We would be adding network bridges tagged on different VLANs. Our model would involve network isolation using VLANs (assume 1 VLAN = 1 customer). So as a new client is brought on board, we need to provision a new VLAN (bridge). Understandibly we could pre-populate some of these, however...

Good day, Understanding that it’s possible to install Proxmox on top an existing Debian Squeeze installation, is it possible / has it been attempted to install Proxmox on top an existing Ubuntu OS? Steaming from previous posts, we are dealing with several compliance restrictions. Several...

Good day, Are there any plans / methods currently available that enable apparmor functionality on the Proxmox host itself. We are dealing with several compliance restrictions in our environment and apparmor would be desirable in our circumstance. I understand that apparmor can be installed...
