Dear All,
I have installed Gluster FS v. 1.3.12 on 2 server with Debian 4.05,
in AFR with client side replication, explained in this page:
http://www.gluster.org/docs/index.php/Setting_up_AFR_on_two_servers_with_client_side_replication
Tested to work!
:-)
Now, my idea:
Use a Xen Hypervisor with image disk data for DomU machines on GlusterFS
repository
In my Gluster FS client machine (based on Centos 5.2), I have create
a DomU machine with image file stored in local disk
(/var/lib/xen/images/), Called "Debian4"
Start and finish installation without problems!
Now, I have moved image file from /val/lib/xen/images/ to my GlusterFS
directory (/mnt/glusterfs/)
O.k., checked that image file, I'm go to modify DomU configuration with
new image disk path....
First setting:
disk = [ 'file:/mnt/glusterfs/debian40.img,hda1,w' ]
Start DomU, I retry this error:
xend.err 'Device 768 (vbd) could not be connected. losetup /dev/loop0
/mnt/glusterfs/debian40.img failed'
Into log explained error is:
domid: 22
qemu: the number of cpus is 1
Watching /local/domain/22/logdirty/next-active
xs_read(): vncpasswd get error.
/vm/353e360e-bcdd-f237-595e-85013704aad7/vncpasswd.
char device redirected to /dev/pts/4
qemu_map_cache_init nr_buckets = 10000

I/O request not ready: 0, ptr: 0, port: 0, data: 0, count: 0, size: 0
Triggered log-dirty buffer switch
Second setting:
disk = [ 'tap:aio:/mnt/glusterfs/debian40.img,hda1,w' ]
Machine start and stop
Into log explained error is:
qemu: could not open hard disk image
'aio:/mnt/glusterfs/debian40-dnsldap.img'
Watching /local/domain/21/logdirty/next-active
xs_read(): vncpasswd get error.

O.k., people have a solution?
Many Thanks,
Enrico Valsecchi
