Subject: [ovirt-users] Reclaim/Trim/issue_discards : how to inform my LUNs about disk
space waste?
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).
