Overprovisioning or disk space issue

[Vittorio]

Hi all

I'm wondering if I have an overprovisioning or disk space issue

I have two VMs, one with a 50GB disk and one with 32GB disk on an SSD of 250GB.

On the first one I have Home Assistant and trying to upgrade it I get the yellow triangle on the VM name.

This is the result of the command pvesm status

Name Type Status Total Used Available %
local dir active 57278576 4715256 49624032 8.23%
local-lvm lvmthin active 148299776 147676916 622859 99.58%

and this is the result of df -h from the Home Assistant VM that I'm trying to upgrade

Filesystem Size Used Avail Use% Mounted on
udev 1.5G 0 1.5G 0% /dev
tmpfs 301M 1.8M 299M 1% /run
/dev/sda2 49G 20G 27G 43% /
tmpfs 1.5G 0 1.5G 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 1.5G 0 1.5G 0% /sys/fs/cgroup
/dev/loop0 89M 89M 0 100% /snap/core/7270
/dev/loop1 89M 89M 0 100% /snap/core/7169
tmpfs 301M 0 301M 0% /run/user/1000

It seems that from within the VM there is 20GB left and from the local-lvm side it's almost full?

What does it mean and what I can do to solve it?

Thanks
Vittorio

it seems your local-lvm is nearly full (99.58%)

what is the output of

lvs

?

but before this I removed a test VM that I recreate.

So now the local-lvm space is around 69%

My question, I'm not expert about virtualized storage and volume manager, is why happened this while I have free space within the VM where Home Assistant was going to be upgraded?

I also see that my local storage (root) is bigger (55GB) than what I really need (probably 25GB would be enough).
Is there a way to resize local from 55gb to 25gb and resize local-lvm from 141gb adding the 30gb removed from local?

Thanks

it happened because lvmthin is a thin provisioned storage, where you can overcommit

you did make a bunch of snapshots and those are not free (in terms of disk space)

not easy no,...
