I need to run the storage as local and and converted lvm-thin to ext4 by newfs /dev/mapper/pve-data then mounted it as /var/lib/vz in fstab
I have added the entry
/dev/mapper/pve-data /var/lib/vz/ ext4 defaults 0 1

also tried
/dev/mapper/pve-data /var/lib/vz/ ext4 defaults 0 0

systemd gives me a timeout error at boot up.
dev-mapper-pve\x2ddata.device: Job dev-mapper-pve\xddata.device/start time out.
Timed out waiting for device /dev/mapper/pve-data

fsck is clean.
After I go into recovery mode and do a mount -a it works fine...

I can't run zfs as my raid controller won't allow it (HP Proliant)

Please don't format a thin-pool with a filesystem directly! This only causes confusion (both for people in this forum like myself, and for the system when it tries to boot up):
* a thinpool is a logical volume inside which you create thinly provisioned logical volumes (in that respect it acts more as a volume group)
* if you want to remove the thinpool and use it as ext4 directory storage - remove it with `lvremove` and create a regular ('thick') LV - which you can then format

Keep in mind that all those operations may destroy data (some definitely will) - so make sure you have a working backup!

Else the concepts of LVM are quite well explained in the wiki-entry of ArchLinux: https://wiki.archlinux.org/index.php/LVM

I hope this helps!

Glad that explained things! please mark the thread as 'SOLVED' - it helps others in similar situations.
Thanks!
 
I solved by by deleting and creating the LVM.... You have to get to total storage available when you create the thick LVM.
