Hello.
I'm playing with libgfapi network disks, over IB and all is working
fine, but not disk locking (and true rdma transport).
I use virtlockd, and with fuse mount, locking works as expected.
But when i converted disk definitions to libgfapi, locks are not created
(but qemu starts and works fine). I used direct and indirect locking -
same result : qemu working fine, no locks.
my revelant xml section:
<disk type='network' device='disk'>
<driver name='qemu' type='raw' cache='writethrough' iothread='1'/>
<source protocol='gluster'
name='pool_test/gentoo-virtio-lib1-sys.img'>
<host name='X.X.X.X' port='24007' transport='rdma'/>
</source>
<target dev='vda' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04'
function='0x0'/>
</disk>
I also tried devices <lease> but it also doesn't work:
<lease>
<lockspace>somearea</lockspace>
<key>somekey</key>
<target path='/data/nfs/lockd'/>
</lease>
# virsh start gentoo-virtio-lib1
błąd: Uruchomienie domeny gentoo-virtio-lib1 nie powiodło się
błąd: internal error: Lockspace for path /data/nfs/lockd/somearea does
not exist
well, lockspace exists...
# ls -al /data/nfs/lockd

razem 0K

Are libgfapi based disks supported by virtlockd? Is there a bug. Am I
missing something?
My test system:
# uname -r
3.14.24-gentoo
# libvirtd -V
libvirtd (libvirt) 1.2.10
# virtlockd -V
virtlockd (libvirt) 1.2.10
# qemu-x86_64 -version
qemu-x86_64 version 2.1.2, Copyright (c) 2003-2008 Fabrice Bellard
# glusterfs -V
glusterfs 3.5.20141204.7b160e3 built on Dec 8 2014 19:03:37
(normally 3.5.2, but was curious if 3.5 series nightly buld will enable
true RDMA transfer, not IPOIB. - it did not).
Best regards
