I originally setup a cluster with pve and pve2 and have zfs pool, I then wanted to add my r630 cluster to it, since it is using RAID I did not configure zfs. After doing that it seems I am losing space?

This is my current setup:

I had a backup I wanted to restore and see that I only have 49.7 G available on local, the lvm-hdd-01(dev/sdb) is HHD where as local, I thought was mapped to /dev/sda is SSD.

In your screenshot of the LVM overview you have 3 LVs running on it.

What is the output of vgs, pvs and lvs?

Code:

  lvm-hdd-01   1   0   0 wz--n-   <1.82t <1.82t
  pve          1   3   0 wz--n- <892.25g 16.00g

Code: 
root@pve-630:~# pvs

  /dev/sdb   lvm-hdd-01 lvm2 a--    <1.82t <1.82t

Code: 
root@pve-630:~# lvs
  LV   VG  Attr       LSize   Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  data pve twi-aotz-- 756.80g             0.00   0.25
  root pve -wi-ao----  96.00g
  swap pve -wi-ao----   8.00g
 
As you can see, there is another LV called "data". Simply add this as storage under "Datacenter -> Storage". But limit this to the R630, since the others have a ZFS.
 
It's already there I thought. ok I see now, that did it! Thanks

Here is another question, "lvm-2" is made up of RAID SSD's and lvm-hdd-01 are RAID HDD, can I make one LVM with both (all) of them together ? I have a few more virtual disks (HDD) I am adding as well.

Am I correct that Virtual Disks configured via RAID should not be configured in ZFS pool?
