One workaround that comes to my mind is to power up the VM, write a large file and delete it and run fstrim -av.Another approach is to create an additional LV inside the guest, use dd to fill it in and then blkdiscard and delete the LV . It will force the fisk to be fully allocated Best Regards,Strahil Nikolov Thanks Arik, Is there a fix that can be applied to current versions as 4.5 release and subsequent testing/approval is some way off/ _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/HXTHUA5QFBBCLM...
