<P><FONT SIZE=2>Hello Javier.<BR>
<BR>
<BR>
The destination node "v" uses a shared storage (via nfs) to access /srv/cloud and "disk.0" can be accessed from both machines ("v" and "b"). A symlink seems not no be used for the image(s):<BR>
<BR>
<BR>
id=36:<BR>
<BR>
oneadmin@v:~/var/36/images$ ls -la /srv/cloud/one/var/36/images/disk.0<BR>
-rw--w--w- 1 oneadmin cloud 41943040 2010-06-11 14:13 /srv/cloud/one/var/36/images/disk.0<BR>
<BR>
<BR>
<BR>
id=38:<BR>
<BR>
oneadmin@v:~/var/36/images$ ls -la /srv/cloud/one/var/38/images/disk.0<BR>
-rw-rw-rw- 1 oneadmin cloud 41943040 2010-06-11 14:55 /srv/cloud/one/var/38/images/disk.0<BR>
<BR>
oneadmin@v:~/var/36/images$ ls -la /srv/cloud/images/2<BR>
-rw------- 1 oneadmin cloud 41943040 2010-06-09 10:36 /srv/cloud/images/2<BR>
<BR>
oneadmin@v:~/var/36/images$ ls -la /srv/cloud/images/ttylinux.img<BR>
-rw-r--r-- 1 oneadmin cloud 41943040 2010-03-30 13:57 /srv/cloud/images/ttylinux.img<BR>
<BR>
<BR>
<BR>
The file-permissions seems to be different. Could that be a potential problem?<BR>
<BR>
<BR>
<BR>
<BR>
thanks<BR>
Marco<BR>

<BR>
Hello,<BR>
<BR>
Can you check that /srv/cloud/one/var//36/images/disk.0 is accessible<BR>
from destination node (I suppose "v")? Also check if that it is a<BR>
symlink the target file is readable there.<BR>
<BR>
Bye<BR>
