This is a known issue when you remove the last snapshot with a running VM. If you stop the VM before deleting the snapshot, this will not happen. The only way to reclaim the space now is: 1. Stop the VM 2. Create snapshot 3. Delete the created snapshot This will merge the new empty snapshot into the old top volume, which has 1G extra space for every snapshot you created in the past. Since the VM is not running, we can safely shrink the top volume to the optimal size after the merge. A little better way is to call the Disk.reduce() API - this can be scripted: 1. Stop the VM 2. Reduce the disk to optimal size 3. Start the VM Use the API: http://ovirt.github.io/ovirt-engine-api-model/4.4/#services/disk/methods/reduce Or the SDK: http://ovirt.github.io/ovirt-engine-sdk/4.4/services.m.html#ovirtsdk4.services.DiskService It is possible to fix this in libvirt 6.0, and may also solve other problems with snapshots, but this is a very delicate change. If you think this is important to fix, please file a vdsm bug: https://bugzilla.redhat.com/enter_bug.cgi?product=vdsm Nir _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@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/6LBI2PT6K62VEQQCBQHHJC3DQSF4N2WX/
