Nobody is just an NFS built-in. I think this generally occurs when the UID and GID of the files on the NFS server do not have an analog on the client.

In other words, if on the server the files are 1001 and the client doesn't have a 1001 the client will see 'nobody'. There are also all sorts of NFS server arguments that you can use to force this condition (I beleive).

Neil,

I suspect that you are having the same issue described in [1].


[1] https://bugzilla.redhat.com/show_bug.cgi?id=858880
I unfortunately don't have access to view this bug...

"You are not authorized to access bug #858880."

Is there any progress on repairing it, or do you know if there is a
work round in the meantime?
You can try going into the nfs share manually and

chown 36:36 *

i.e., if your iso domain is at /export/iso:

chown 36:36 /export/iso/<uuid>/images/<uuid>/*

Note that the uuid is different in both cases above, and for each
domain.

Not sure if this will help or not, but it's worth a shot.

Mike

Thanks!

Regards.

Neil Wilson.

The owner 36:36 should be vdsm.kvm and not vdsm.vdsm
Do you have a group kvm with gid = 36?

Alex
Hi Alex,

I only have a group called vdsm with gid 36...no group kvm.

grep 36 /etc/group
vdsm:x:36:

Same as my user..

grep 36 /etc/passwd
vdsm:x:36:36::/home/vdsm:/bin/false

Thanks
After messing around with permissions 640 644, 777 and changing
groups, every time I clicked on the "images" tab my whole storage
would go offline, so I've now destroyed by old ISO domain and
re-created it with these exact steps.

Just tried destroying my ISO domain and added a new one, but still the
images don't show.

mv iso-domain iso-domain-old
mkdir iso-domain
chown -R 36:36 iso-domain
ls -al
drwxr-xr-x.   3 vdsm vdsm  4096 Oct 16 17:37 iso-domain

In ovirt I went to storages --> NEW domain, and added it as NFS ISO,
it added, I then activated it and then uploaded a small ISO image, but
still the image doesn't show.

On my host I ran...
vdsClient -s 0 getIsoList `vdsClient -s 0 getConnectedStoragePoolsList`
------ ISO list with proper permissions only -------

I see that on my host the uid and gid of 36 are vdsm:kvm not sure if
this is somehow related?

This is what I see in my server.log when I click on images now...
(note that my storage stays online now though since re-creating)

Going to your host console, what do you see on the owner and permitions of the ISO domain? I had a similar issue with a ubuntu server that exported the NFS share as nobody.nobody instead of vdsm.kvm on the host. That domain was activated but I couldn't get to the share with a "permeation denied" error"
Strangely enough, I see a similar issue...

drwxr-xr-x. 3 vdsm nobody 4096 Oct 16 17:37 10.251.193.5:_iso-domain

Any ideas how to correct it?
