Although it is not officially supported by proxmox, I would suggest you to try ZFS, installed on local PVE node. Just install PVE on a single ssd disk and build a ZFS pool with the rest HDDs.You can "partition" this ZFS pool in as many slices (datasets) you want and use it for vms,isos etc...

ZFS cannot do that. I mean it cannot do real time syncing of data like DRBD does. You can use zfs send/receive to backup your primary server to a secondary server but you cannot work in dual primary mode like in DRBD, so no live migration is possible. DRBD works fine for me (no HA), no issues...

Your packages seem outdated, e.g pve-qemu-kvm 1.4-17 where it should be 2.1-10 whith latest pve. Have you also tried with 3.10 kernel?

Re: Can there be such configuration: 6 machines in the one cluster, but the HA uses o As long as the cluster configuration is unique to the entire cluster I don't believe you can do that. You need to have 2 separate clusters for that. But wait for a confirmation from somebody else to be sure.

Re: Can there be such configuration: 6 machines in the one cluster, but the HA uses o Yes, you can. You can enable HA just for vms you need for.Just go to Datacenter -> HA and enable HA for vms you need HA.The remaining vms will be handled manually by you.

* vzprocps: not correctly installed * ksm-control-daemon: not correctly installed Try to re-install above packages by using "apt-get", maybe it is related to them.

Also try to disable ballooning if it is already enabled.

Hello It looks like something related with your storage subsystem. What kind of vm disk are you using? (qcow2,raw,lvm)

Check this link: https://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-networkscripts-interfaces.html Don't forget option: ONBOOT=yes

You are confusing Debian with CentOS.The correct path for that is: /etc/sysconfig/network-scripts/ifcfg-eth0

Actually I have done the opposite.ZFS has control over disks and DRBD sits on top of each ZVOL.So, each VM lives on separate DRBD resource -> ZVOL.Each ZVOL is snapshotted automatically by using zfs-autosnapshot. If something goes wrong I have to bring DRBD resource down.Do ZFS rollback on...

Hello Wasim, I have tested both Ceph and GlusterFS.Ceph on two node cluster does not perform well and it is not recommended anyway.For 3+ nodes setup with a lot OSDs, Ceph will be my first choice.I don't believe that this cluster will grow at least in the near future, so I would prefer to use a...

hello and happy new year! I have two nodes with latest proxmox installed, without HA enabled. As vm storage I currently use ZoL(zfs on linux) on both nodes. Each vm reside on separate ZVOL which is replicated with DRBD on both nodes.Thus DRBD sits on top of each zvol and each vm is a separate...

I suggest you to not use HA on two node cluster.It is better to use manual mode in such setup.

If you cannot create a file on / then you must have some problem with filesystem on that or it's backing storage(corruption?).Do you have free space on / ? Also /etc/pve is read-only.Do you have cluster? What is the quorum status? (pvecm n , pvecm s) Can you post some lines from dmesg and...

hello Maybe this can help: https://access.redhat.com/solutions/442193 Also have you tried pve-kernel 3.10 instead?

hello I'm testing latest PVE with kernel 3.10.0-5-pve on two nodes with DRBD without HA. It was working fine until yesterday when I did apt-get update/upgrade/dist-upgrade. On updates list, it showed a new version for kernel 3.10.0-5-pve and a new version of PVE (3.3-140), so I decided to move...

Is this ssd the only disk drive on your server? If not, try to disconnect all other disk drives during the installation and connect them back after the installation. Proxmox needs to install grub on the first drive.Failure detecting it so can lead in such problem. Or you can try with an older...

Have you tried disabling UEFI in BIOS during installation and enabling Legacy mode?

Yes, that applies to 3.3 too. Follow that guide for two node cluster.
