I have a clean install with openmediavault as backend NFS and cannot get it to work. Keep getting permission errors even though I created a vdsm user and kvm group; and they are the owners of the directory on OMV with full permissions.
The directory gets created on the NFS side for the host, but then get the permission error and is removed form the host but the directory structure is left on the NFS server.
Logs:
From the engine:
Error while executing action New NFS Storage Domain: Unexpected exception
From the oVirt node log:
2019-11-29 10:03:02 136998 [30025]: open error -13 EACCES: no permission to open /rhev/data-center/mnt/192.168.1.56:_export_Datastore-oVirt/f38b19e4-8060-4467-860b-09cf606ccc15/dom_md/ids
2019-11-29 10:03:02 136998 [30025]: check that daemon user sanlock 179 group sanlock 179 has access to disk or file.
Make sure sanlock user is a member of vdsm and kvm groups
id -a sanlock
should list also kvm and vdsm.
This is something that
vdsm-tool configure --force
systemctl restart libvirtd
systemctl restart vdsm
should set if not set already.
