Thank my friend very much. TMUX is great. It successfully solves my needs.

Thank my friend very much. This question has been bothering me since debian10. Now I finally have a detailed answer. In fact, my working environment is a little special. The server is in a completely isolated state. It is stipulated that it cannot turn on SSH and has no GUI. It can only work...

It seems that all the secondary development based on Debian system cannot use shift+pageup/pagedown in the TTY interface to turn pages up and down, including the current pve7.2. Who knows why? But all RedHat based products can turn pages, CentOS, Oracle Linux, rockylinux, almalinux reason...

Official help manual My title is to ask two questions, but I mainly described that the first one that cannot be realized is memory, and you taught me how to realize online memory expansion, so I went on to ask CPU questions

Thank you very much. I have finished this, but the CPU hot plug cannot be realized, Follow the official manual.

If it is KVM, the maximum memory is 8GB, and the default memory is 4GB, I can directly use the command: virsh setmem test VM 5120m -- config -- live Set the memory to 5GB To increase memory heat But I can't find this setting on PVE

As you said, it's true that you went through conversion halfway, so it's very slow. However, when writing RBD directly, the rate is normal, and the object storage cephfs. The default parameter you give is that you can't store disk images. It's recommended to allow storage, so the performance can...

Sorry, you may have misunderstood what I mean, I just want to consult whether there is an optimization method.If other IO consumption is considered, there should be a consumption value, and we should be controllable.

In the environment at that time, I have used ceph's command: { systemctl stop ceph-osd@0.service ceph osd out 0 ceph osd crush rm osd.0 ceph osd rm osd.0 ceph auth del osd.0 } I completely deleted the osd, and because I couldn't delete the last mon, I finally had to rebuild the system. Later, I...

Importing virtual machine disks on Proxmox ve Gui is very slow, only 40-150MB/s, but I can directly use the rbd command to import the speed to reach 340MB/s, so is there any need to optimize? Similar to the problem of glance https://bugs.launchpad.net/glance/+bug/1390386

Because we don't know where the configuration path on pve is, otherwise we can find it and delete it, but I recently researched and found that: pve will limit the cluster to at least a few osd and monitors. This problem makes you unable to delete it in the end. It means that the establishment of...

But I modified the ceph.conf, and it still can't be cleared.

yes！

root@p1:~# pveceph mon destroy p3 no such monitor id 'p3'

This command has been tested and cannot be implemented

According to my test, it is actually very simple. It can be achieved by adding 10 lines of code. Copy the snapshot file while copying the disk. When the copy is completed, you only need to modify the vm configuration file, and then refresh it. NFS, ceph and local disk

It is recommended that when migrating disks, migrate the snapshots together, otherwise you will be prompted that the source disk cannot be deleted. (You can add a select button to choose whether to migrate with the snapshot), now I can only modify the virtual machine configuration by command...

Because the old machine has been destroyed, it will be replaced by a new machine, the name will still be P3
