  2. Add/Rescan undisplayed disk
  3. Passthrough sata drivers
  4. Delete PVE cluster
  5. Reinstall ceph
  6. Pin older kernel
  7. Delete snapshot forcedly
  8. Unlock virtual machine
  9. Unlock lxc container

Transfer .img disc image file to Virtual Machine(vm) disk.

  • The example is to transfer openWRT image file to VM disk.

bash

qm importdisk [VM id] [image path] [storage id]

Example:

bash

qm importdisk 100 ./openwrt.img local-lvm

It would be rescan all disk which belongs to a specific virtual machine. If find undisplayed disk, it’ll add to virtual machine’s configuration

bash

qm rescan --vmid [VM id]

Example:

bash

qm rescan --vmid 100

bash

# list all sata drivers
ls -l /dev/disk/by-id/

# add sata to virtual machine, where sataX is sata0, sata1 ...
qm set 100 -sataX /dev/disk/by-id/xxxxx
# Example:
# DO NOT add disk with part1, part2 ..., like /dev/disk/by-id/xxxxx-part1
qm set 100 -sata0 /dev/disk/by-id/xxxxx

bash

# list nodes and information
pvecm nodes
# delete the node
pvecm delnode [NodeName]
# list all nodes' configuration directory
ls -l /etc/pve/nodes/
# delete or move to another location
mv /etc/pve/nodes/[NodeName] /root/[NodeName]

Examples:

bash

# remove this pve-node3 cluster
pvecm nodes
pvecm delnode pve-node3
ls -l /etc/pve/nodes/
mv /etc/pve/nodes/pve-node3 /root/pve-node3

bash

rm -rf /etc/systemd/system/ceph*
killall -9 ceph-mon ceph-mgr ceph-mds
rm -rf /var/lib/ceph/mon/  /var/lib/ceph/mgr/  /var/lib/ceph/mds/
pveceph purge
apt purge ceph-mon ceph-osd ceph-mgr ceph-mds
rm /etc/init.d/ceph
for i in $(apt search ceph | grep installed | awk -F/ '{print $1}'); do apt reinstall $i; done
dpkg-reconfigure ceph-base
dpkg-reconfigure ceph-mds
dpkg-reconfigure ceph-common
dpkg-reconfigure ceph-fuse
for i in $(apt search ceph | grep installed | awk -F/ '{print $1}'); do apt reinstall $i; done
pveceph install

Latest kernel may not be supported to a old hardware, requires fix the kernel version

bash

proxmox-boot-tool kernel pin [KernelVersion]

Examples:

bash

proxmox-boot-tool kernel pin 5.13.19-6-pve

bash

qm delsnapshot [VMID] [SnapshotName] --force

Examples:

bash

qm delsnapshot 100 update00 --force

bash

qm unlock [vmid]

Examples:

bash

qm unlock 100

bash

lct unlock [lxc-id]

Examples:

bash

lct unlock 100
