Re: [PVE-User] pve-kernel-4.13.13-5-pve hang with high IO

As long as you microcode is older than June 2017 there is no way that there are mitigations for Meltdown and Spectre as Intel was only made aware of the flaws back in June 2017. Same goes for the BIOS as the vendors require the microcode from Intel to include into their updates. Regarding the

[PVE-User] Quick question regarding node removal

Hi, in the documentation to pvecm [1] it says: At this point you must power off hp4 and make sure that it will not power on again (in the network) as it is. Important: As said above, it is critical to power off the node before removal, and make sure that it will never power on again (in the

Re: [PVE-User] Local interface on Promox server

You could use qm terminal to connect to the serial console. Ctrl + o will quit the session. You need to configure your VMs to provide a serial console, e.g. by adding "console=tty0 console=ttyS0,115200n8" to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and running "grub-mkconfig -o

Re: [PVE-User] PVE Firewall Port forwarding...

And how would you handle the situation where you want to use dport 10200 on several VMs on the same host? I don't think that this will work reliably in a cluster, where VMs migrate between hosts. Am 06.04.19 um 16:25 schrieb Gilberto Nunes: Hi there... Is there any way to use port forward

Re: [PVE-User] Proxmox Ceph Cluster and osd_target_memory

No in-place way to convert between but you can set one drive at a time to "out" to migrate data away, then to "off" and destroy. Then remove the OSD and recreate with filestore. Let it sync and once finished, do the next drive. Am 19.02.19 um 12:16 schrieb Gilberto Nunes: > Hi > > I have 15

Re: [PVE-User] Cluster mixed hardware behavior (CPUs)

To be most flexible in a HA setup you would take the minimal denominator on the CPU architecture / feature side. E.g. if you have 5 hosts with SandyBridge CPUs and 5 Hosts with Skylake CPUs you would limit the CPU type to SandyBridge. This enables you to migrate VMs back from a Skylake node to

Hi all, is it possible to move a VM's disks from one Ceph cluster to another, including all snapshots that those disks have? The GUI doesn't let me do it but is there some commandline magic that will move the disks and all I have to do is edit the VM's config file? Background: I have two PVE
