Do you have that NFS storage accessible to vdsm user? the folder you are mounting better be owned by vdsm:kvm Best, Fil -- Dmitry Filonov Linux Administrator SBGrid Core | Harvard Medical School 250 Longwood Ave, SGM-114 Boston, MA 02115 On Fri, Jun 28, 2019 at 9:16 AM Andy Michielsen <andy.michielsen(a)gmail.com&gt; wrote:

Hello All, Thank you for the replies. I read the url and I think I did it all as discribed. I did a ssh into the synology and changed the owner and group for the volume I created and the folder I'm sharing with NFS. I did the the mounting test on the engine and also on the node. And I unmounted it afterwards. But I will try and log on with the vdsm user. Have to look for the password and then I will try and mount again. Kind regards.

When you added the permissions on the NFS export did you map the user and group ID to those names? IE the userid is 36? ________________________________ From: Andy Michielsen <andy.michielsen(a)gmail.com&gt; Sent: Tuesday, July 2, 2019 9:29 AM To: Staniforth, Paul Cc: users Subject: [ovirt-users] Re: Using a synology as an nfs storage Hello, I'm still strugling with adding a nfs share from my synology share.

I have done my configuration and I'm able to mount the share manually on the node with a command. Also on the server with the engine on I can mount it manually. But when I want to do it through the webinterface to add a data domain it say the permissions are wrong. Any idea's on how to figure this out ? Kind regards.

Hi, everything look good. I would prefer to hostnames (not asterisk) in /etc/exports my /etc/exports would look like this: /volume1/GETQUADATA001 ovirtnode001.get.be <http://ovirtnode005.get.be/>(rw,async,no_root_squash,no_subtree_check) ovirtnode002.get.be <http://ovirtnode002.get.be/>(rw,async,no_root_squash,no_subtree_check) ovirtnode003.get.be <http://get.be/>(rw,async,no_root_squash,no_subtree_check) ovirtnode004.get.de <http://ovirtnode.004.get.de/>(rw,async,no_root_squash,no_subtree_check) ovirtnode005.get.be(rw,async,no_root_squash,no_subtree_check) Don’t forget to reexport: # exportfs -ra The jumping point here is, could you create directories with (SPM Host) on that location with vdsm user? [root@ovirtnode005 ~]# sudo -u vdsm mkdir /mnt/nfs/xx [root@ovn-elem tmp]# ls -lad /mnt/nfs/xx drwxr-xr-x. 2 vdsm kvm 6 3. Jul 05:19 /mnt/nfs/xx Best Regards, Oliver

I ssh'd to my Synology NAS and created the user and group vdsm/kvm with id 36 and chown'd the share. The permissions on shared folders for oVirt are 0750, no where near as open as 0777... Not had any problems with it over the years, just need to change the ownership of the new shares before using them. On Wed, 3 Jul 2019 at 08:20, Andy Michielsen <andy.michielsen(a)gmail.com&gt; wrote:
