Hi. In order to use drbd you must have a block device below it, so in zfs case you can use only zvols for that purpose.Datasets cannot be used with drbd.

Yes, it can. Follow this guide: http://docs.oracle.com/cd/E19253-01/819-5461/gamnq/index.html

Yes, if you have selected zfs as fs on installation.It is the native zfs file system.But except from the default datasets thay pve creates during installation,you can create other datasets if you want.

What about trying the native zfs dataset instead of zvol for that purpose?

No, only kvm.

You could have a third proxmox node offsite,with similar configuration as main site, which will receive zvols(an their snapshots) via zfs send/recv.Not sure about this since I haven't tried it. The main thing is that you won't loose your data since your zvols will be intact.

I use zfs autosnapshot script (https://github.com/zfsonlinux/zfs-auto-snapshot) which takes automatic hourly,daily,weekly,monthly snapshots on each host. I use also zfs send/recv manually to copy this zvols on a external storage over network.The only drawback is that in case of snapshot rollback...

Actually I have created zvols before zfs gui integration in proxmox, so I created them manually by using zfs commands to create zvols.Each zvol same size on both nodes.After creating zvols use drbd config to attach those zvols to separate resources(which corresponds to each vm disk).After doing...

Primary/Primary in order to have live migration working.I'm also doing auto snapshots on zfs level to protect each drbd resource(vm).

Hi Yes, I'm using drbd ontop of zfs (zvols) on a two node cluster without issues.I had zfs installed before proxmox integrated it in the latest versions.I've updated proxmox to latest version and I'm using that zfs version now.I'm using separate drbd resources per vm (zvol).

For two nodes, DRBD is the way to go.The problem is that it cannot scale up.You can just use "pairs" of DRBD nodes.HA with just two nodes and DRBD will be an issue(you have to use qdisc). Otherwise start with 3 nodes and use Ceph.

Then something must be wrong with your setup. Check how "local" storage appears in the following screenshot (marked with red circl).

Hello again, After carefully reading your previous posts I think I've managed to understand what you are talking about. :) I have also 2 PVE nodes. On each PVE I have a local storage configured with the same path (/var/lib/vz).Now, If I navigate through the web interface to Datastore ->...

Hi Local storage cannot be mounted on two proxmox nodes at the same time.To do so, you need a clustered filesystem (like GFS for example).Ext3,Ext4,XFS etc are not clustered filesystems so they should be mounted on just one node. In your scenario I would go with DRBD in dual Primary or...

hi Have you tried to boot from rescue cd (windows cd, if vm is win) and try to repair bootloader? Can you verify that you see the contents of hdd from there(data)? Use ide drive instead of virtio for this procedure for simplicity. Finally if you manage to boot correctly you can install virtio...

hi Try booting in Sysrescuecd,chroot and finally repair grub-loader. Then try to boot again...

Congrats to PVE team! Great work (as usual).ZFS integration in pve-kernel is a dream come true...

Can you try with win7 32bit? This link suggests a bug on virtio drivers but I don't know if it's related to your problem: https://bugzilla.redhat.com/show_bug.cgi?id=1135824 Have you updated proxmox to latest version? What's the underlying storage type on /var/lib/vz?How it is formatted...

hello all, I have a windows 2003 machine which is not properly aligned (4K block),so disk performance is not optimal. I would like to know if there is a tool (preferably free) to properly align NTFS partition to 4K block sector inside windows VM. I can do both offline/online conversion but I...

I've managed to have a stable win2000 vm by giving the following options: - 1 cpu core - Inside vm, on device manager -> computer -> update driver -> ACPI PC
