I have an automatic process setup. It's still pretty new and obviously in need of better error handling because now I find myself in a bad state. I run snapshot-create-as across all my vms, then do zfs replication to the target backup system, then blockcommit everything. virsh snapshot-create-as --domain $vm snap --diskspec $DISK,file=$VMPREFIX/"$vm"-snap.qcow2 --disk-only --atomic --no-metadata --quiesce ... virsh blockcommit $vm $DISK --active --pivot Normally this works fine, though something went wrong on the 20th. something happened to make the blockcommit fail, but the -snap file got deleted (note to self - check return code from blockcommit command!) So now I'm in a state. The domain i still running. but it's running off the -snapshot that is in the xml. I googled around for how to recover a blockcommit from a deleted snapshot, but didn't find anything. (pointers welcome) [root@vm1 images]# virsh domblklist serv1r2 Target Source ------------------------------------------------ vda /var/lib/libvirt/images/serv1r2-snap.qcow2 fda - hdb /var/lib/libvirt/images/virtio-win-0.1.126.iso I can see the size increasing on the deleted file in lsof: qemu-kvm 48994 49033 qemu 97u REG 0,44 1855913984 1078 /var/lib/libvirt/images/serv1r2-snap.qcow2 (deleted) ... qemu-kvm 48994 49033 qemu 97u REG 0,44 1856110592 1078 /var/lib/libvirt/images/serv1r2-snap.qcow2 (deleted) -- so, do I need to rollback the zfs snapshot image or is there some other way to recover from this snafu?
