I just wanted to thank you for your input, I had the same issue.
Command to relaod udev rules for the next one : udevadm control --reload-rules && udevadm trigger
Long story short, we had to reboot our proxmox cluster (6 machines) after a switch change and everything went south.
We had HA enabled and at some point, each server decided to start every VM...which corrupted their disks on the shared storage.
But this was our fault, here is what we did on the...
If I may add my points:
- add the ClamAV unofficial sigs by default, very easy to install (https://github.com/extremeshok/clamav-unofficial-sigs)
- add the DKIM signature to outgoing email (via the web UI)
- add some options to manage the SSL certificate (with Lets encrypt for example) from the...
Thanks for your reply.
I'd say the box is already here as iptables is running on the physical hosts.
That's not a problem to migrate all the rules, it will take some scripts writing skills but we can do it.
Hello,
Today we have a cluster of ASA5540 behind the production network, which is composed of VM on proxmox hosts. All VM have public IP addresses.
We are in the process of retiring the Cisco ASA and we are evaluating others options available.
The ASA does IPv4/6 allow/deny, rate limiting and...
Hello all,
I'm running proxmox on 8 nodes with a shared SAN on fiber channel exposing an LVM volume.
Today I need to expand the storage for the VM but I doesn't want to shutdown all the VM on the LVM volume.
I've read here: http://www.tldp.org/HOWTO/LVM-HOWTO/sharinglvm1.html and there...
Hello,
I seek advices and examples of network design with virtualised nodes.
I have a brunch of Dell R710 (4 GigE NICs) and 2 Cisco 4948 switchs.
My plan was, for each server, to connect 2 interfaces on one switch and the two remaining on the other switch, then create a LACP trunk on each...
Hello,
I have 6 servers in a cluster and I need to change the subnet of these servers.
Is is possible without breaking all the config of the cluster ?
Is there a particular way to do it ?
Bonus question : is it possible to have vmbr interfaces without addresses ?
Thanks you for your help.
Ok.
I have 2 servers with the same disk configuration :
/ 20 Gb (ISO, Containers, Templates)
VG 900Gb (Images)
When I do an (offline) migration from one to the other, it tries to store the disk image on / and not on the VG.
Why ?
Thanks you
Hi Tom,
Thanks for your fast reply.
Ok now I understand the partition scheme.
My problem with migration in a cluster is that if I migrate a VM to an 2.0 upgraded server, it will try to store disks in /var/lib/vz and not in the LVM.
I unchecked "Images" in the "local" storage and activated it...
Hello,
I installed some servers from scratch on PVE 2.0 and upgraded some others.
On the new installed 2.0, /var/lib/vz is on a dedicated partition and there is no space left on LVM.
On the upgraded 2.0 /var/lib/vz is a directory on the root partition and VM disks are on LVM.
As I read, LVM...

Hi,
Thanks for your reply.
I'm not an expert on kernel modules..so can you explain me how to add the 18xx driver to the current kernel ?
Or give me a how to :)
Thanks again
[SOLVED] - Please update kernel for ARC-18xx cards
Hello,
I have a ARC-1880 RAID card and I can't use it on 2.0 because the kernel is too old (2.6.32 and I need a least 2.6.36).
Is it possible to have a new kernel soon ?
Thanks you
