  6. [SOLVED] Can VM hard disk size be bigger than single SSD in Ceph Storage?

    I have a 3 node ceph proxmox cluster for storage with node1 7*143GB ssds, node2 7*143 ssds, node3 7*218 ssds. Now I have read through the http://docs.ceph.com/docs/jewel/architecture/#mapping-pgs-to-osds however it is not 100% clear to me if I can create a VM with hard disk size 300GB using Ceph...
  7. Adding new Ceph node to existing cluster

    I have a Ceph and Proxmox running without any problems. Now considering future scenarios such as running out of space on current Ceph cluster. 1. Creating a new node with drives, adding to the already existing cluster makes sense. However, how do we add the new drives in the new node to the...
  8. [SOLVED] 4 Nic Bond Doesn't Work

    Thanks for the reply Ashley, It was indeed the switch which was not tagged for all the vlans. Once they were tagged and vlans were defined in the interfaces file, it all worked well with vmbr from those vlans. Best,

  10. Proxmox uses full swap and uses much more memory than allocated for VMs

    This is excellent Tom, thanks a lot. I m sure it will be helpful to many of us experiencing similar problem. However, I have already upgraded the server to the latest 3.3 and I have not experienced the same issue since the upgrade. It has been 4 days since upgrade and memory usage and allocation...
  11. Proxmox uses full swap and uses much more memory than allocated for VMs

    Here is the give ram amount to each kvm. I have several of them so i dont think it is only one server's fault. None of them run at 100%, three of them usually average at 90 - 95 percent, and others are usually around %70. After restarting the whole server, the problem doesnt happen for weeks or...
  12. Proxmox uses full swap and uses much more memory than allocated for VMs

    There is no additional software running on the server. Clean installation of 3.2 proxmox. Below is the output of "top". And I am certain that memory allocated by me for those 9 servers are not higher than 5GB. However, as I can see from "top" command they consume more Ram than allocated for...
  13. Proxmox uses full swap and uses much more memory than allocated for VMs

    I have 9 KVMs running on Proxmox 3.2 and total of 5G of ram given to 9 KVMs. Proxmox server has 8GB of ram and 7GB of SWAP. For most of the time when i check summary of the server i see that it uses all 7.50Gb of ram and all 7GB of full SWAP. Well that is bad for multiple reasons. I can not run...
  14. [SOLVED] kernel: vmbr0: port 4(tap107i0) entering disabled state

    I dont think my problem on the original post is the same problem as we see here. I dont have any bounded interfaces and it was working without any problems before. So as for http://forum.proxmox.com/threads/17598-vmbr0-port-10(tap109i0)-entering-disabled-state problem, then what is the...
  15. vmbr0: port 10(tap109i0) entering disabled state

    This can not be good. I have too many disconnects from ssh clients. Below started happening in kernel log recently ~~ 2weeks. The system was at 3.0. when the first time it started happening. Updated to 3.1 no change. It was working beautifully for over a year :( Any idea how to solve this issue...
  16. ProxmoxVE will change LICENCE?

    Very simple question... Without enterprise subscription, now running 3.0. They will roll out 3.2. Can't I simply upgrade to 3.2? Also assume 3.2 got to be stable when they put on their site for Download, yes?
  17. ProxmoxVE will change LICENCE?

    What i understand is the following: pve-enterprise will get bug fix updates and such. Then what happens when I am running 3.0-20 version and I want to upgrade lets say 3.2 when it is out? Technically I can download it for free but I can not upgrade from 3.0 to 3.2 for example? "Beginning...
  18. ProxmoxVE will change LICENCE?

    "We are just afraid of possibility, that the next new versions and bugfixes are going to be only for pve-enterprise subscribers." is that the case?
  19. KVM Centos Hdd almost empty, but backup 35G

    Good Day, I m seeing a wierd pattern when i take a backup of one of my KVMs. I used to have over 40G of data in that kvm centos, then removed all those files/folders not there is only 1G of data in that server. I took a backup of that kvm on proxmox and it took forever and i see that the...
