Hello list,
In short: I am experiencing a problem where trying to start a VM which
is allready running on a different libvirt host. Starting it fails,
thanks to sanlock, but the disk dies on the original hypervisor and the
vms filesystem is rendered read-only.
Long version:
i have the following setup:
Two machines (H1 and H2) using CentOS 6.2 with the packages:
qemu-kvm-0.12.1.2-2.209.el6_2.4.x86_64
libvirt-client-0.9.4-23.el6_2.7.x86_64
libvirt-0.9.4-23.el6_2.7.x86_64
libvirt-lock-sanlock-0.9.4-23.el6_2.7.x86_64
They share two NFS folders, one for filesystems ( net set up as a
libvirt storage pool ) and one for sanlock.
sanlock is started without watchdog.
/etc/libvirt/qemu-sanlock.conf:
auto_disk_leases = 1
disk_lease_dir = "/opt/mln/sanlock"
host_id = 51
( host_id is 52 on H2 )
cat /etc/libvirt/qemu.conf | grep sanlock
lock_manager = "sanlock"
A virtual machine is created ( with virsh create ) on H1 using the
following xml:

I can log in to the VM and everything is fine. Next, i try to start the
VM on H2, i get the following error:
error: Failed to create domain from libvirt/rhel1.locktest.xml
error: internal error Failed to acquire lock: error -243
All seems well, but now the VMs filesystem is in read-only state....

qemu: terminating on signal 15 from pid 3138
Back on H1 there are multiple lines in the qemu log for the VM:
block I/O error in device 'drive-ide0-0-0': Input/output error (5)
block I/O error in device 'drive-ide0-0-0': Input/output error (5)
block I/O error in device 'drive-ide0-0-0': Input/output error (5)
block I/O error in device 'drive-ide0-0-0': Input/output error (5)
block I/O error in device 'drive-ide0-0-0': Input/output error (5)
Can someone please help me understand why the filesystem dies on the
original host? Is this an NFS problem? What should I do differently?
Many thanks in advance,
K
