Hi,

In my hosts, I see that /etc/lvm/lvm.conf shows :

issue_discards = 0

Can I enable it to 1 ?

Thank you?

You can change it but it's not going to affect the lvm behavior in VDSM since we don't use the host lvm config file. This will be probably addressed as part of bz1017284 as we're considering to extend discard also to vdsm images (and not direct luns only). https://bugzilla.redhat.com/show_bug.cgi?id=1017284 -- Federico
