[Users] Unable to add ISOs to default ISO storage domain

sorry to jump on the bandwagon here - ive also uploaded an iso to the ISO domain - which i said yes to create it locally on the engine-management host.
default exported as /mnt/iso - i didnt have to manually do anything to add it to the domain, only activate it.

cat /etc/exports
/mnt/iso        0.0.0.0/0.0.0.0(rw)     #rhev installer


i uploaded my iso like so:

 /usr/bin/engine-iso-uploader -i ISO -u admin at internal -r ovirtmgr.foo.com:8443 upload os_2.0-784729f4-19.iso

It finished successfully, the iso is owned vdsm.kvm and has the default 640 permissions.
I tried setting them to 755 as mentioned in one of these threads - but that didnt help..

$ tree -pug /mnt/iso

/mnt/iso
    └── [drwxr-xr-x vdsm     kvm     ]  23340f35-95ca-4b46-90ec-0c8b83a82786

        └── [drwxr-xr-x vdsm     kvm     ]  images
            └── [drwxr-xr-x vdsm     kvm     ]  11111111-1111-1111-1111-111111111111
                └── [-rw-r----- vdsm     kvm     ]  os_2.0-784729f4-19.iso

I havent rebooted the ovirtmgr host yet incase that "fixes" it

Any ideas?

Andrew and Chris,

You shouldn't need to manually place images on the NFS share and 
subsequently chmod them. The ISO uploader should be doing both the 
uploading and the chmod-ing for you, and if it is not doing this then 
it's a bug.

Here is a Successful Example:
[root at ovirt ~]# vim keith.iso <-- Create a junk file.
[root at ovirt ~]# chmod 400 keith.iso <-- Set restrictive perms on it.
[root at ovirt ~]# ovirt-iso-uploader -i iso1 upload keith.iso
Please provide the REST API password for RHEV-M (CTRL+D to abort):

// Let's check our work...
[root at ovirt ~]# mount <ip scrubbed>:/data/ovirt/iso1 /mnt/isodomain/ <-- 
mount the iso export domain
[root at ovirt ~]# su - vdsm
-bash-4.1$ ll 
/mnt/isodomain/92cf90c2-3698-48b5-84fd-d8e4f8684547/images/11111111-1111-1111-1111-111111111111/keith.iso
-rw-r-----. 1 vdsm kvm 10 Feb 3 07:45 
/mnt/isodomain/92cf90c2-3698-48b5-84fd-d8e4f8684547/images/11111111-1111-1111-1111-111111111111/keith.iso 
<-- w00t!


Andrew, to help me debug, could you...
1. Is your ISO export domain being exported by a *nix system? If so can 
you reply with the line in /etc/exports that does the exporting. It 
looks something like mine below...
[root at inductor ~]# cat /etc/exports
/export *(rw,sync,no_root_squash)

2. Send me the output of "tree -pug" from the iso domain:
[root at ovirt ~]# su - vdsm
-bash-4.1$ cd /mnt/isodomain/92cf90c2-3698-48b5-84fd-d8e4f8684547/
-bash-4.1$ tree -pug
dom_md/ images/
-bash-4.1$ tree -pug images
images
└── [drwxr-xr-x vdsm kvm ] 11111111-1111-1111-1111-111111111111
<snip>

Cheers,
Keith
