Dear all,

I have the following volume group and I am reading this guide (my cluster is on Proxmox 4.4 so I installed the tools mentions on Linbit website):

--- Volume group ---
VG Name pve
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 12
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 3
Open LV 3
Max PV 0
Cur PV 1
Act PV 1
VG Size 3.64 TiB
PE Size 4.00 MiB
Total PE 953164
Alloc PE / Size 543565 / 2.07 TiB
Free PE / Size 409599 / 1.56 TiB
VG UUID FAGgtH-slrq-XNGB-OVLj-UTkA-dpFd-lT6tid


My question is the following: can I just replace lvcreate -L 511G -n drbdthinpool -T drbdpool by lvcreate -L 511G -n drbdthinpool -T pve so that it can use the my pve volume group?

Is it safe for my current logical volumes?

Thanks for your reply.
