+==== local-lvm on ZFS ====
+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:
+<code bash>
+# create 50GB thin volume:
+zfs create -s -V 50G hddpool/lvm
+readlink /dev/zvol/hddpool/lvm
+../../zd32
+</code>
+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:
+<file ini /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.*|"]
+}
+</file>
+<code bash>
+pvcreate /dev/zvol/hddpool/lvm
+vgcreate pve /dev/zd32
+# Create thin pool data volume
+lvcreate -l 100%FREE --type thin-pool --name data pve
+</code>
+And disable nodes restriction in ''Datacenter'' --> ''Storage'' --> ''local-lvm'' to have ''local-lvm'' visible on all cluster nodes.
+==== growing lvm volume ====
+<code bash>
+zfs set volsize=200GB hddpool/lvm
+pvresize /dev/zd32
+pvs
+lvresize -l 100%PVS pve/data
+lvs
