You should not be running trim in a container/virtual machine
Why not? That's, in my case, basically saying "you should not be running trim on a drive exported via iscsi" Perhaps I shouldn't be but I'd like to understand why. Enabling thin_provisioning and fstrim works and gets mapped to the underlying layers all the way down to the SSD. My underlying VG is less than 50% occupied, so I can trim the free space by creating a LV and then removing it again (I have issue_discards set) FWIW, I did issue fstrim in the VMs with no visible issues at all. Perhaps I got lucky?
Here is some info: https://wiki.archlinux.org/title/Solid_state_drive
I don't see VM or virtual machine anywhere on that page.
