Created attachment 1121017 [details] The log of step2 Description of problem: As summary Version-Release number of selected component (if applicable): libvirt-0.10.2-56.el6.x86_64 qemu-kvm-rhev-0.12.1.2-2.487.el6.x86_64 libvirt-lock-sanlock-0.10.2-56.el6.x86_64 sanlock-2.8-2.el6_5.x86_64 How reproducible: 100% Steps to Reproduce: 1. Setup libvirt sanlock on a host: On host A # setsebool sanlock_use_nfs 1 && setsebool virt_use_nfs 1 && setsebool virt_use_sanlock 1 # cat /etc/libvirt/qemu-sanlock.conf auto_disk_leases = 1 disk_lease_dir = "/var/lib/libvirt/sanlock" host_id = 1 user = "sanlock" group = "sanlock" # cat /etc/libvirt/qemu.conf lock_manager = "sanlock" # cat /etc/sysconfig/sanlock SANLOCKOPTS="-w 0" # service wdmd restart; service sanlock restart; service libvirtd restart 2. Create a guest and do external snapshot # cat guest.xml <domain type='kvm' id='1'> ... <disk type='file' device='disk'> <driver name='qemu' type='qcow2' cache='none'/> <source file='/var/lib/libvirt/images/c2.qcow2'/> <target dev='vda' bus='virtio'/> <alias name='virtio-disk0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </disk> ... </domain> # virsh create guest.xml Domain cc created from guest.xml # virsh list Id Name State ---------------------------------------------------- 6 cc running # virsh snapshot-create-as cc s1 --disk-only --diskspec vda,file=/tmp/cc.s1 error: Failed to acquire lock: File exists Snapshot file created but the snapshot failed. # ll /tmp/cc.s1 -rw-------. 1 qemu qemu 2.2M Feb 4 10:17 /tmp/cc.s1 # virsh snapshot-list cc Name Creation Time State ------------------------------------------------------------ When I rm the file and create it again: # rm /tmp/cc.s1;virsh snapshot-create-as cc s1 --disk-only --diskspec vda,file=/tmp/cc.s1; error: Timed out during operation: cannot acquire state change lock Actual results: As step2 Expected results: No errors and snapshot create success.
