Backup Issue think its lvm PE?

[sahostking]

Hi

Getting this error when backing up:
INFO: Volume group "pve" has insufficient free space (4095 extents): 20000 required.

Have a VM of 800GB that can't seem to backup. Is it due to PE size?

This is my current setup:

root@vz-cpt-1:~# vgdisplay
--- Volume group ---
VG Name pve
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 292
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 5.45 TiB
PE Size 4.00 MiB
Total PE 1429763
Alloc PE / Size 1425668 / 5.44 TiB
Free PE / Size 4095 / 16.00 GiB
VG UUID CqWVYc-G8Qp-9sEa-fnat-fNz2-6zrf-xb7SZw

root@vz-cpt-1:~# pvdisplay
--- Physical volume ---
PV Name /dev/sda3
VG Name pve
PV Size 5.45 TiB / not usable 1.98 MiB
Allocatable yes
PE Size 4.00 MiB
Total PE 1429763
Free PE 4095
Allocated PE 1425668
PV UUID tIjDZg-tXeB-6I2M-Vzn5-HYGF-hj1W-gNvbjI

Also if I lvreduce will it break proxmox?
What is the best way to do this? Anyone come across this yet?

Diy you set the 'size' parameter somehow (maybe in /etc/vzdump.conf)? If so, remove it and try again.

I only added it earlier today in hopes it would fix this error.

I get these errors now which is new after removing it:

Read error at byte 0, while reading 4096 bytes: Input/output error

Seems to only happen with very large VMs over 100GB or so. Anything smaller seems to backup just fine as per below:

Anything larger than 100GB gets this which is only happening to 2 of our VMs as the rest are all small:


Are you sure you want to remove VM 101? This will permanently erase all VM data.

Figured this out by the way. Seems when we installed Proxmox we did not give it enough space for Snapshots. We busy fixing that using a new server for testing first but so far seems to be the issue.
