Hi all,
Need your support for figuring out the problem, this issue has hijacked our
work.
The issue is , when starting the system VM, management server tries to
initialize templates, in which it fails.
As a result, I am not able to see the default templates in the list of
templates.
Cloudstack has a local copy of the ova file and tries to copy this into the
mounted secondary storage under a folder with a unique id.
Then it tries to change the permissions on the file using "sudo chmod 777" -
but this command fails.
If I try and execute this command from the shell directly as root, it also
fails with the same error.
There should be a setting on the mounted file system that allows the root
userid to do super user operations on the files in the mounted file system.
"no_root_squash". We have checked and this setting is defined for the exported
file system. I guess the question is now, why is the "no_root_squash" not
working. It should allow the root user to do root operations on the files, but
it is still giving us an error message for the chmod command. It seems that our
secondary storage is implemented with ZFS instead of NFS as documented in the
Cloudstack install. I don't know if there are issues with no_root_squash and
ZFS, might be worth investigating that.
Perhaps there are other settings on the ZFS configuration that we need to set?
All we should need is to be able to set the permissions on these files to
allow the local file to be accessible to the cloudstack user.
Please let me know your thoughts on this.
