Hi Dag, I tested the write in NFS and its working normally , and for the SMLog I didn't found such log file Please note that I'm using xenserver 6.5 Best Regards Ghaith Bannoura -----Original Message----- From: Dag Sonstebo [mailto:Dag.Sonstebo@shapeblue.com] Sent: Tuesday, October 4, 2016 4:31 PM To: users@cloudstack.apache.org Subject: Re: Error in creating new instances Hi Ghait, When you mounted the NFS share in XenCentre did you check if you could write to it? (you can test this from command line on the XenServer)? One other thing to check is the /var/log/SMLog file on the XenServer in question.

First of all check network connectivity between the two. If this is OK check the permissions / ACLs set on your NFS share – chances are the XenServer IP is not permitted. You can also try to just temporarily mount the NFS share directly from the XenServer / XenCentre (remember to unmount it later before putting it back into production) and see if you can access the share.
