Resized container disk no space released

[tom.b]

Hi There,

I have resized my container disk size following this guide:
https://phil.lavin.me.uk/2017/12/pr...78c426cc671d689d7ef2effecb3417#comment-273170

It al worked well, but i don't see the free disk space on my host machine getting larger, this is still the same.

Someone got an idea?
thanks.

Hi,
Assuming you're using an lvm-thin storage device, shrinking a disk won't affect the storage usage. LVM-thin devices only allocate blocks of storage when they're written [1], so when you create the initial container, whether it's 8Gb or 80Gb, only a couple of hundred megabytes will be reported as used. If proxmox reports more storage usage than the container is using, you could try running pct fstrim <vmid> to discard unused blocks in the container.
