Looks like one of the disks has bad sectors. Are you using the hardware card to do the raid? With ZFS, that is a bad idea. If not, check this link: https://www.forwardingplane.net/2014/03/replace-zfs-raidz1-disk/

I suggest trying the steps here. https://forums.freebsd.org/threads/54541/ They should shed light on what is accessing your dataset.

Thank you! This issue caused me quite a headache in the past.

I hope you are backing up your containers and vm's. Just because it is on ZFS et al, doesn't mean it is safe from all disasters.

Is there any particular reason why you need to use DRBD9 vs CEPH? CEPH is integrated pretty well into Proxmox.

Are you sure you have the permissions set correctly on that NFS share?

Are you running Proxmox in a virtual environment (Oracle's Virtualbox for example)? You will have trouble getting Win 2008 to work under those setups. Use an actual physical box.

That was the only suggestion I could find from scouring the other forums on this problem, but I didn't find it very helpful advice.

What error gets logged when you try to restart pveproxy on px1? Make sure these daemons are running on it also. https://pve.proxmox.com/wiki/Service_daemons

I never tried it on a spanned volume, but why not install the converter application and test? Of course, make a backup of your data on that spanned volume first and make a snapshot of the VM. You could also create a fourth disk, copy the data from D to it, and then remap that fourth disk to D...

I agree with fireon. For migrating from VMWare, I just install VMWare Converter on the VM to migrate and send the resulting VMDK file to my Proxmox shared storage or whatever. You then create a new "hardware matching" VM within Proxmox and map its hard drive to the VMDK file (edit the...

Guys, check the docs here: http://pve.proxmox.com/wiki/User_Management

Of course, I simply wanted to make sure the drives/controller themselves were not faulty in some way. I was not suggesting you use something other than Proxmox.

Just wondering, have you tried installing VMWare ESXi 6.5 on that box to see if the drives are detected correctly? At least you can verify that they are okay using another Linux variant.

Did you see this post? https://forum.proxmox.com/threads/pve-3-4-cluster-failed-node-recovery.23720/

What type of shared storage are you using? Some types only allow RAW. Try an NFS share, etc.

Is your backup in RAW format? I believe that ISCSI supports RAW only and you may be attempting a recovery of qcow2, etc.

I would recommend just getting some disks and using the ZFS option during Proxmox instllation. You can choose up to 8 drives I believe. Just go with zraid mirror. Do not worry about configuring anything on your controller.

You are playing with fire using just 2 nodes. Perhaps this still applies: http://zeldor.biz/2011/03/drbd-set-sync-speed/
