Create Template on NFS secondary Storage

Hi all,

We are currently using Cloudstack 4.1.0 managing XenServer 6.0.2 servers.


Since recently, I don't know what cause this to appear on our system but
 went we create a template from a Instance the template (.vhd) is upload on
on the secondary storage (NFS) but in a subdirectory  ex:

from the Storage VM:
/mnt/SecStorage/7f6f1f2d-2d6f-3ec6-a25e-fb25f2704167/template/tmpl/3/246
root@s-184-VM:~# ls -l
total 8
drwxr-xr-x 2 4294967294 4294967294 4096 Oct  3 19:35
02ee28f2-0c02-f936-3ca3-099cfe3f3a20
-rw-rw-rw- 1 4294967294 4294967294  314 Oct  3 19:36 template.properties

root@s-184-VM:~# ls 02ee28f2-0c02-f936-3ca3-099cfe3f3a20/
fe2fa941-3030-412d-8c35-b0e80a2e7e09.vhd


So, when we create a new Instance from the template, the Instance creation
fail with the following error in the management-server.log:

2013-10-03 15:48:01,190 WARN  [xen.resource.CitrixResourceBase]
(DirectAgent-255:null) Catch Exception
com.cloud.utils.exception.CloudRuntimeException on

to com.cloud.utils.exception.CloudRuntimeException: can not create vdi
in sr 451078ee-d335-bdb0-c41c-cd86524be3ea

if I move the VHD file in the 246 folder, it works !

Does anyone have this problem too  or have an idea of where it would come
from ?

Thanks !

Hi Kirk and Travis,

Thanks for your fast answer and reply. The problem was the one Kirk
mention, NFFSSR.py have been replace by an hotfix,  we recently apply a
xenserver hotfix and since then  we had problem creating templates. Pretty
much in the same time we add a new zone so I wasn't sure which event cause
the issue which is why I did not say it in the first email.

doe anyone know if there is a doc reference of all scripts replace on
xenserver by cloudstack? if it is not the only script.

That said, the only doc I've found regarding updating hypervisors is
http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.2.0/html/Admin_Guide/maintain-hypervisors-on-hosts.html
which contain an outdated link.

Thanks again !

Re: Create Template on NFS secondary Storage

Posted by Kirk Kosinski <ki...@gmail.com>.
Did you patch the hosts recently?  That is the likely cause.  The
patched NFSSR.py that CloudStack copies to XS hosts can be overwritten
by some patches.  Without the patched NFSSR.py, when secondary storage
is mounted it reverts to the default XenServer behavior of including an
extra directory named after the SR UUID.

One solution is to copy the correct NFSSR.py manually from the
management server to /opt/xensource/sm/NFSSR.py on every XS host.  There
will be several versions of the script in
/usr/share/cloudstack-common/scripts/vm/hypervisor/xenserver/ on the
management server, and you can check the MD5 checksums beforehand to
confirm it is the problem.

Another solution is to force CloudStack to setup the host again, which
includes copying NFSSR.py.  To do this, unmanage the cluster in
Cloudstack, clear the "tags" parameter for every host in the cluster (xe
host-list, xe host-param-clear uuid=<uuid> param-name=tags), re-manage
the cluster, and wait a few minutes.

Best regards,
Kirk

Can you check the permissions on the actual folders, 244 and 246 and see if they differ or have different owners?
