Hi,
Thanks I just edited the export file as following.
/srv/cloud 192.168.1.6(rw,no_root_squash,,sync) .
Then I restarted the system .
Now its working fine
But I'm facing the onemore problem that when I try to save the VM using the
following command .
onevm saveas <vm-id> <disk-id> <imagename>
onevm shutdown <vm-id>
Here I can see the new Image details when I do oneimage show <imagename>
but when I try to deploy the the new VM using the above image I get the
following error .
Tue Sep 13 16:16:57 2011 [TM][D]: Message received: LOG - 59 tm_clone.sh:

such file or directory
Here is the output of oneimage show 32
ID : 32
NAME : alliswell
TYPE : OS
REGISTER TIME : 09/13 16:12:13
PUBLIC : No
PERSISTENT : No
SOURCE :
/srv/cloud/one/var/images/def71f75ceab7d2fa444927b8e1588633c547422
STATE : rdy
RUNNING_VMS : 1
IMAGE
TEMPLATE
DEV_PREFIX=hd
NAME=alliswell
TYPE=OS
Since I'm able to save/ clone the VM , I guess there is no problem with user
rights access to the nfs shared folder .
what else may be the problem ..? why it could not save the image .
regards
Bala
