    [SOLVED] proxmox-pve uninstall right after ISO install

    I installed PVE 7.4 directly from ISO. Added an enterprise license to it and did an update/upgrade through the interface. Now I need to install vlan & ifenslave. Both end up in: root@pve03:~# apt install vlan Reading package lists... Done Building dependency tree... Done Reading state...

    ZFS over iSCSI

    We're researching a storage solution to replace current solution. Few commercials vendors in play, but since we're huge fans of ZFS, using ZFS over iscsi might be an option as well. Is anyone here on the forum using it in production? Any issues you ran into?

    Speccing PBS server

    Hi all, We're currently thinking about moving one cluster to proxmox. Storage used will be about 130 TB. I read about and tested PBS, works like a charm. But not on spinning rust. First question: what compression / dedup rate can I realisticly expect? The 130 TB storage in use are 90% Ubuntu...

    New cluster - storage solution

    For a new cluster we are investigating storage solutions. Cluster(s) will be 20 nodes in size, so nothing local and had to do failover and such. Current clusters running on ultra-low-latency nvme, so ceph, NFS and zfs over iscsi ruled out. Been speaking to various suppliers this week. Some of...

    Add to existing cluster

    Hi, Question: we're disassembling a proxmox cluster and moving to a new one. What we have left is one node with local storage in this cluster running 5 VM's. We like to physically move this server to a new location and add it to another existing proxmox cluster. Is this possible? What...

    Disks not migrated and can't start

    Hi, I had a server in our proxmox cluster that gave some weird warnings. I decided to reboot it. It had 3 VM's on it. While rebooting it, proxmox decided it was going to live on another host in the cluster. But... it had about 1 TB of local LVM storage on the rebooted server. So .. the old...

    Communication failure to storage in GUI

    Hey all, When I look in the interface at the storage (any of the available storage options on this node), I get a "communication failure (0)". VM's running on these storage arrays are fine, it's only a GUI thing. The same storage arrays do show up on other nodes just fine. See attachment. How...

    Can't do anything with container

    Hi, I've had an issue where a LXC CT locks for the 2nd day in a row when the backup process starts (snapshot). The backup actually never starts, it just hangs. Killing the backup job brings the CT back online. So I thought that maybe stop/start the CT would help. However.. the stop process...

    node semi onlin

    Hi all, I'm having a weird issue with a node. It's online, pingable, but it's half in the proxmox cluster. Proxmox does see it as online, but communication fails. When I reboot it, proxmox does tell me it's offline and it comes back online when the reboot is finished. Output from the node...

    IOPS limit

    Hey all, I have a weird issue. I setup IOPS limit to 500 on a KVM VM. It seems to work, from within the VM, see this graph from zabbix: http://imgur.com/a/ZhMO0 So far so good. This VM is the only VM living on the storage platform. If I look at the IO activity on the storage platform, it's...

    Storage migration failing

    Hi all, I'm trying to migrate disks between 2 storage endpoints. Both are NFS, but on different storage arrays. Both storage arrays are almost idle. This is the error, after 100% migration flow: TASK ERROR: storage migration failed: mirroring error: VM 255 qmp command 'query-block-jobs' failed...

    Add node - reboot all vm's

    Hi, I have a proxmox cluster running with 13 nodes. I wanted to add a node to it. Somehow it then decided to restart all running VM's. All 200-something VM's were restarted. Finally all VM's come back online, I see the 14th node in the cluster, but it appears offline, as is one other node. The...

    Destroy cluster configuration

    Hi, Due to some failures we have a non working cluster. How can I completely destroy the cluster configuration on all 3 members to I can recreate the cluster? The machines have containers running, so I can't reinstall the machines alltogether.

    Disable firewall from command line

    Hi, What is the easiest way to completely disable the firewall from command line, the "proxmox way" ? Someone f*cked up the firewall config and we don't have access to the web interface any more and cluster config is broken.

    Affinity groups

    Hi, In oVirt we're used to configuring affinity groups, i.e. web1 & web2 can never run on the same node. Is such a thing possible in Proxmox? Thanks!

    KSM

    Hi all, On my currently 7 node cluster I see on all nodes that KSM sharing is 0. Is there a setting I have to make to enable KSM sharing? 90% of my VM's are the same OS, on the old platform (oVirt) we did see KSM sharing active.

    Migrating VM "no such cluster node"

    Hi, I just added the 5th node to my proxmox cluster. All seems well. It's shown as online in the interface, I can interact with it from the interface (create VM's). However .. I'm not able to migrate VM's onto it. It tells me "no such cluster" node after picking it from the drop down menu...

    Destroy entire cluster

    Hi all, In my efforts to break Proxmox before taking it into production I guess I succeeded :) Now I'd like to remove the entire cluster configuration from all nodes, but can't seem to find a howto for proxmox 4.2. Any ideas?

    Advice on storage

    Hi all, We're going do deploy a proxmox cluster soon. I'd like to get some advice from the people who are using it on what storage method is best. We have a ZFS cluster on the netwerk, so I can use both NFS & iSCSI. What would be the configuration to use so that I'm able to use most of the...

    Filesystem snapshots

    Hi, I've been a long time happy user of Proxmox, untill we decided to move to ovirt. Now that Proxmox is able to work with LXC, we're considering adding a Proxmox cluster. One of the questions I have, can't find the answer: if using containers and requesting a backup, will proxmox create a tar...
