Looking to purchase a refurbished economical desktop to run Proxmox at home for testing. Was looking on amazon. Anyone have suggestions?

Say I have 3 drive slots. For random I/O would I be better off with ZFS RAID1 over 2 drives or ZFS RAID5 over 3 drives? Last time I tried to setup RAID1 over 3 drives on Proxmox it would not work.

I need to move a large VM from one server to a newer one in different location. Is there a way to stop the VM and move it to new server and restart on new server? The backup process seems to take a very long time so I was looking for a faster method.

I installed Proxmox 6.0-1 on an older Supermicro server using ISO image. Used ZFS and several drives in ZFS raid array configured from the proxmox install GUI. On boot I get this every time. Command: /sbin/zpool import -N 'rpool' Message: cannot import 'rpool' : no such pool available Error...

I have Proxmox 5.3 installed on 4 drives configured in a raid6 like array. Say one drive is throwing errors. How do I remove and replace just that single drive? When I installed proxmox were all drives in array configured to be bootable? How can I insure the replacement is also?

I have an OVA image file. How do I go about loading that into Proxmox?

I have a simple install of Proxmox on four SATA drives in a raid z2 array. As I understand adding an SSD based ZIL device will greatly improve write speeds? How do I add the device? Is this correct assuming default ZFS setup was used when installed? zpool add rpool log /dev/sde If I...

Installed proxmox on four new enterprise sata drives in ZFS raid 10 like array using the proxmox-ve_5.3-1.iso installer. I updated to latest version using apt-get and rebooted. Then I added a few test VMs to it. It ran for a week perfectly. Rebooted it yesterday then received this error and...

I installed proxmox from latest 5.2 ISO image onto 6 sata drives using ZFS-Z-3. Upon reboot I get this error: "error: compression algorithm inherit not supported" "Entering rescue mode..." Any idea what is wrong?

I am trying to install latest proxmox 5.2 on a Supermicro system with 12x hot swap 3.5 bays and a SAS 9210-8I SATA/SAS controller connected to them. https://www.broadcom.com/products/storage/host-bus-adapters/sas-9210-8i I am not trying to use the controller for raid just as a sata controller...

I have a Proxmox host machine with one large Centos KVM image running. The proxmox host has two drives in a ZFS raid1 like array. It has a single second drive used for backups. I want to backup this image and move it too new machine as fast as possible. This is the only KVM running on this...

I want to create a backup of a stopped VM as fast as possible. There will be no other VM's running at time I am creating this. Is there a way to speed up the process at price of system load etc?

Is it possible to move a KVM from a proxmox 4.x host to a proxmox 5.x host without doing the backup and restore? Wondered if it would be faster to somehow shut it down then move it with ssh?

I currently have several KVMs running inside a simple proxmox host that do a lot of random disk io. The proxmox host is using two sata drives in a RAID 1 type array. I was thinking of moving to 6 drives in a RAID 6 type array. Would that improve disk io speed significantly or not? I found...

I have some older servers I use for internal testing. What is the process under proxmox to update the microcode without a bios update?

I have a Supermicro X10SLH-F motherboard with a Xeon E3-1230 CPU. The CPU is 4 core and 8 thead. Before updating bios I saw 8 cores under top. After updating bios too R 3.1 now I only see two cores. I did load optimized defaults and looked at advanced cpu settings and have found nothing. Any...

Have basic proxmox server using two drives in ZFS RAID1 like format. What would be better or more efficient for KVM clients to run on top of this XFS or EXT4?

I have a number of Centos 7 KVM virtual machines running under Proxmox. They are mixture of XFS and EXT4 file systems. Is there anyway to zero out the unused disk space so the backups of the entire KVM done with Proxmox are not so large?

I had one drive in a ZFS raid 10 type array of 4 SATA dries start emailing errors: "Currently unreadable (pending) sectors". I replaced it and reinstalled proxmox. How do I tell if there are any issues with the other drives?

I am seeing this error: smartd[2918]: Device: /dev/sdd [SAT], 24 Currently unreadable (pending) sectors smartd[2918]: Device: /dev/sdd [SAT], 24 Offline uncorrectable sectors This proxmox server has four 3TB drives setup as ZFS RAID 10 type setup. Does this mean sdd is simply bad?
