Hi all,

New to Sanlock, I try to make it work on Ubuntu 12.04 (using the following ppa : https://launchpad.net/~wb-munzinger/+archive/ppa-sanlock)

Libvirt-bin and libvirt-sanlock are both version 0.9.11-2.2.ubuntu.1

Sanlock is version 2.1-4.ubuntu.1

I just cannot make it work :

Here is my conf :

My NFS storage is mounted in fstab on both hosts :

MYIP:/SANLOCK              /var/lib/libvirt/sanlock  nfs         hard,nointr,_netdev     0             0

First I don’t want to reboot my hosts in case of concurrent access, I just don’t want libvirt to be able to launch my qcow2, so as far as I understood, no need to modprode softdog (tell me if I’m wrong).

Cat /etc/default/sanlock

Enabled=1

Sanlock_opts=”-w 0”

Must I use wdmd ? It’s enabled=0 for now…

In my /etc/libvirt/qemu-sanlock.conf

Auto_disk_lease = 1

Disk_lease_dir = “/var/lib/libvirt/sanlock”

And I do have different host_id (1 and 2) !

In qemu.conf :

Lock_manager = “sanlock”

So I’ve got two .qcow2 on /var/lib/libvirt/sanlock and a __LIBVIRT__DISKS__:0 created :

Sanlock status :

P -1 listener

P -1 status

S __LIBVIRT__DISKS__:1:/var/lib/libvirt/sanlock/__LIBVIRT_DISKS__:0

(And S __LIBVIRT__DISKS__:2:/var/lib/libvirt/sanlock/__LIBVIRT_DISKS__:0 on the second host)

Now when I virsh start myvm1 on my 1^st kvm, then a sanlock direct dump a __LIBVIRT__DISKS__ shows nothing except offset lockspace etc but no value (on both hosts).

I can start the same vm1 on the second KVM without warning/error (!)

Nevertheless, it seems that a lock is created on disks because a lock file is created (md5sum I guess).

When now I stop my VM, this md5 lock file is never removed. I must virt-sanlock-cleanup to remove it…

If you could help me, that would be really great.

Thank you.
