[pve-devel] use ext4 discard option for containers?

[Alexandre DERUMIER]

fstrim is still better.

discard mount option has too much overhead

Objet: [pve-devel] use ext4 discard option for containers?

Hi all, 

I wonder if we can/should use the ext4 "discard" option 
for container mounts by default? Is this stable enough? 

Or should users run fstrim inside the container periodically? 

any opinions on that?
