I show free space in my pve volume group, but I can not use all free space in storage "local-lvm".

How I configure it to get 3,28 TB disk free space ?
Thank you
 
I already run this command:

lvresize --poolmetadatasize +3GB /dev/pve/data

I get error message in my proxmox host:
Oct 31 15:25:07 siginjai lvm[948]: No longer monitoring thin pool pve-data-tpool. Oct 31 15:25:07 siginjai lvm[948]: Monitoring thin pool pve-data-tpool.

and Now filesystem in VM goes into readonly mode
 
I am sorry that I am very panic..

I only repeat this command several times
# lvresize --poolmetadatasize +10M /dev/pve/data

this command solve my problem
# lvextend -L+100G pve/data

Okay, everything alright now? The first command only extends the metadata pool of the LV by 10 MB so this might cause the problems with the metadatapool being full since 10M is not very much. Did you manage to extend the data volume to 3.28 TiB?
 
Everything is fine. I already extend the lvm pool to 3.5 TB. The underlying disk is 2.4 TB RAID 10 + 2.4TB RAID1 disk. The raw capacity is about 4.8 TB.
