LVM

• pvs
• vgs
• lvs
• use cfdisk to resize partition where PV is located
• pvresize /dev/sda3
• check with pvdisplay that new size is correct
• lvextend -l 100%FREE pve/data or lvextend -L +20G pve/data

When Proxmox cluster is used it is good to have the same storages on all nodes. It is needed for migration of LXC.

To add local-lvm storage to ZFS based node:

# create 50GB thin volume:
zfs create -s -V 50G hddpool/lvm
 
readlink /dev/zvol/hddpool/lvm
../../zd32

By default Proxmox adds global filter rule to lvm.conf to exclude all zvol and rbd devices So add our /dev/zd32 to accept list:

/etc/lvm/lvm.conf

devices {
     # added by pve-manager to avoid scanning ZFS zvols and Ceph rbds
     global_filter=["a|/dev/zd32|","r|/dev/zd.*|","r|/dev/rbd.*|"]
}

pvcreate /dev/zvol/hddpool/lvm
 
vgcreate pve /dev/zd32
 
# Create thin pool data volume
lvcreate -l 100%FREE --type thin-pool --name data pve

And disable nodes restriction in Datacenter –> Storage –> local-lvm to have local-lvm visible on all cluster nodes.

zfs set volsize=200GB hddpool/lvm
pvresize /dev/zd32
pvs
lvresize -l 100%PVS pve/data
lvs
