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

Andrew and Chris,

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


Here is a Successful Example:
[root@ovirt ~]# vim keith.iso <-- Create a junk file.
[root@ovirt ~]# chmod 400 keith.iso <-- Set restrictive perms on it.
[root@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@ovirt ~]# mount <ip scrubbed>:/data/ovirt/iso1 /mnt/isodomain/ <--mount the iso export domain

[root@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 canyou reply with the line in /etc/exports that does the exporting. Itlooks something like mine below...

[root@inductor ~]# cat /etc/exports
/export *(rw,sync,no_root_squash)

2. Send me the output of "tree -pug" from the iso domain:
[root@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

Cheers,
Keith

It would appear that the problem was the permissions on the files.
after I did a chmod 0755 to the .iso it appeared almost immediately in
the web admin.
Should the iso-uploader script not have changed the permissions of the
file? It appears to have set the correct owner.

Easiest way to go about this, at least the way I go about it...Manually

place your iso images on the NFS ISO share.
This can be accomplished two ways:

Example 1: If you have direct access to your fileserver EG: NAS/etc and
it is linux based.
Simply login and sftp/scp/NFS/CIFS retrieve and/or copy the images into

/export/path/to/iso/domain/<domUUID/images/11111111-1111-1111-1111-11111

1111111
Then chown 36:36

/export/path/to/iso/domain/<domUUID/images/11111111-1111-1111-1111-11111

1111111/*

Example 2: Mount said NFS mount point on another client and copy the
images into it.
Export on NFS server is for example /rhev/iso --> mount
<servername_or_ip>:/rhev/iso /mnt
Copy the images into
/mnt/<domUUID/images/11111111-1111-1111-1111-111111111111/
Then chown 36:36
/mnt/<domUUID/images/11111111-1111-1111-1111-111111111111/*

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

I have been trying to upload ISOs onto my ISO Storage Domain, set up
when I ran engine-setup.
I can run the command and the .iso file is correctly put in place,
however this never appears in the available images for this domain on
the web-admin.
I notice that there are no file entries in

https://xxxx.xxxx.co.uk:8443/api/storagedomains/a677acff-601b-4b6d-86ce-

0798f3833629/files/
just what is given in the verbose output from the uploader.
Any ideas what the problem might be? I have tried a couple of ISOs and
have also done a cleanup and setup.

Below is the verbose output from the uploader:

[admin@xxxx ~]$ sudo engine-iso-uploader -v -f -i ISOs upload
Downloads/TinyCore-current.iso [sudo] password for admin:
