--- Begin Message --- FWIW, depending on how the sum is used it might actually make even more sense to use PSS, i.e., the proportional set size which better accounts for shared memory by dividing that part between all its users, as if e.g. 10 QEMU processes have 100 MB of shared code and what not

2023-05-10 Thread Roland via pve-devel
--- Begin Message --- what about adding zfs datasets as a general type of storage? currently, you need to create a dataset manually and add that as type "dir" to proxmox, to be able to use file backed instead of zvol backed VMs that feels ugly. Am 10.05.23 um 02:08 schrieb Konstantin Filippov:
