Hi,
I have node with 4 LXC Containers
one container about 85GB
one is about 10GB
one about 105GB
and last is 8GB
total of about: 210GB
now. the LVM-Thin Volume show me this details:
Usage: 97.76% (974.18 GiB of 996.50 GiB)
local no any backups / images.

any suggestion how can I "rescan" the volume usage and show the right usage?

Did you trim your disks?
 
You have to enable discard on the vm disk and then run fstrim in the VM or set discard as mount option in the VM.
 
With container there is no need to set this parameter.
 
all of
vm-2161-disk-1
vm-319-disk-1
vm-321-disk-1
vm-324-disk-1
are containers
how can I solve that size issue?

Thanks for that option:
1. is is SAS Disks and not SSD, Guess it does not matter
2. how can I enable discard mount for XLC Containers?
3. trim your fs with fstrim, mean on container level or on main filesystem level?

Thanks again,
as fo #2
This is enabled by default.
so if it's enabled, why I have this issue?
