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 resolved the boot issue. I missed bootdisk: in the conf file. Also, had to add discard=on too scsi0 line. I have a guest centos 7 KVM using LVM. How do I get TRIM to work with LVM?

https://pve.proxmox.com/wiki/Qemu_trim/discard_and_virtio_scsi I managed to make fstrim work by changing: This line: virtio0: local-zfs:vm-101-disk-1,size=1000G To: scsi0: local-zfs:vm-101-disk-1,size=1000G In: /etc/pve/nodes/prx10/qemu-server/101.conf Now it wont boot unless I select the...

How do I make fstrim work? This is a proxmox install with 2 sata drives in zfs RAID1 like array. Thin Provision is enabled on the Image storage drives. I used VirtIO SCSI when creating the VMs. I have one Centos7 install that is XFS filesystem and another that is EXT4. The compressed...

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?

Will it automatically email me if there is any sort of issue?

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?

So I shutdown the proxmox server and replace sdd with a new 3TB drive. How do I rebuild my ZFS RAID 10 array?

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?

Is there a way to just stop the KVM and just move needed files from from one proxmox box to another then start it on other machine?

I have proxmox 4.x server with two sata drives formated with zfs in a raid1 like setup. Simple install. I have one Centos 7 VM on it that is very large and busy. Takes days too do a snapshot backup. Is there anyway to move it to another proxmox server running 5.x without doing the backup...

I have a couple simple Proxmox 4.x servers with internal SATA drives for storage configured for raid1 on ZFS. I need to update to Proxmox 5.x as I understand. What is an easy low down time way to transfer these KVM machines to a temp Proxmox 5.x server so that I can update this server from...

What is: "Target storage ID"?

I have an .OVA file I want to load into Proxmox. Is there an up to date how to on doing this?

Didn't seem to find any packages that failed to install or failed dependencies. Reboot went fine. screen is my new friend though.

apt-get install screen Very good advice. ;<)

This won't accidentally update me too proxmox 5.x will it? Thanks.

On proxmox 4.x I did a "apt-get update" followed by a "apt-get dist-upgrade". My wifi router I was connected to the internet with rebooted when "apt-get dist-upgrade" was almost complete. The proxmox 4.4.x server never lost power or rebooted or even lost Internet access. It was just the Putty...
