Just to be sure I hadn't altered something, I renamed "mnt" in something else and it was indeed recreated.

I tried to make a cleaner install : after cleanup, I recreated "/rhev/data-center/mnt/" and ran the installer again.
It should be automatically created by vdsm, can you please avoid that?
As you can see, it crashed again with the same access denied error on this file : [ INFO ] TASK [Copy configuration archive to storage]

[ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook
But the file permissions look ok to me : -rw-rw----. 1 vdsm kvm 1,0G 20 mars 2018 /rhev/data-center/mnt/10.100.2.132:_volume3_ovirt__engine__self__hosted/015d9546-af01-4fb2-891e-e28683db3387/images/589d0768-c935-4495-aa57-45b9b2a18526/b1884198-69e6-4096-939d-03c87112de10
So I decided to test something : I set a shell for "vdsm", so I could login : su - vdsm -c "touch /rhev/data-center/mnt/10.100.2.132:_volume3_ovirt__engine__self__hosted/015d9546-af01-4fb2-891e-e28683db3387/images/589d0768-c935-4495-aa57-45b9b2a18526/b1884198-69e6-4096-939d-03c87112de10" && echo "OK"
OK As far as I can see,still no permission problem
But if I try the same as "root" :
touch /rhev/data-center/mnt/10.100.2.132:_volume3_ovirt__engine__self__hosted/015d9546-af01-4fb2-891e-e28683db3387/images/589d0768-c935-4495-aa57-45b9b2a18526/b1884198-69e6-4096-939d-03c87112de10 && echo "OK"
touch: impossible de faire un touch /rhev/data-center/mnt/10.100.2.132:_volume3_ovirt__engine__self__hosted/015d9546-af01-4fb2-891e-e28683db3387/images/589d0768-c935-4495-aa57-45b9b2a18526/b1884198-69e6-4096-939d-03c87112de10 : Permission non accorde
Of course, "root" and "vdsm" can create, touch and delete other files flawlessly in this share.
It looks like some kind of immutable file, but is is not suppose to exist on NFS, does it ?

Hi,
In fact it is a workaround coming from you I found in the bugtrack that helped me :
chmod 644 /var/cache/vdsm/schema/*
As the only thing looking like a weird error I have found was :

So I can go one step futher, but the installation still fails in the end, with file permission problems in datastore files (i chose NFS 4.1). I can't indeed touch or get informations even logged in root. But I can create and delete files in the same directory. Is there a workaround for this too ? Everything should get wrote and read on the NFS export as vdsm:kvm (36:36); can you please ensure that everything is fine with that?

Hi,
I wanted to rebuild a new hosted engine setup, as the old was corrupted (too much violent poweroff !) So the server was not reinstalled, I just runned "ovirt-hosted-engine-cleanup". The network setup generated by vdsm seems to be still in place, so I haven't changed anything there. Then I decided to update the packages to the latest versions avaible, rebooted the server and run "ovirt-hosted-engine-setup". But the process never succeeds, as I get an error after a long time spent in "[ INFO ] TASK [Wait for the host to be up]" [ ERROR ] fatal: [localhost]: FAILED! => {"ansible_facts": {"ovirt_hosts": [{"address": "pfm-srv-virt-1.pfm-ad.pfm.loc", "affinity_labels": [], "auto_numa_status": "unknown", "certificate": {"organization": "pfm.loc", "subject": "O=pfm.loc,CN=pfm-srv-virt-1.pfm-ad.pfm.loc"}, "cluster": {"href": "/ovirt-engine/api/clusters/d6c9358e-2b8b-11e8-bc86-00163e152701", "id": "d6c9358e-2b8b-11e8-bc86-00163e152701"}, "comment": "", "cpu": {"speed": 0.0, "topology": {}}, "device_passthrough": {"enabled": false}, "devices": [], "external_network_provider_configurations": [], "external_status": "ok", "hardware_information": {"supported_rng_sources": []}, "hooks": [], "href": "/ovirt-engine/api/hosts/542566c4-fc85-4398-9402-10c8adaa9554", "id": "542566c4-fc85-4398-9402-10c8adaa9554", "katello_errata": [], "kdump_status": "unknown", "ksm": {"enabled": false}, "max_scheduling_memory": 0, "memory": 0, "name": "pfm-srv-virt-1.pfm-ad.pfm.loc", "network_attachments": [], "nics": [], "numa_nodes": [], "numa_supported": false, "os": {"custom_kernel_cmdline": ""}, "permissions": [], "port": 54321, "power_management": {"automatic_pm_enabled": true, "enabled": false, "kdump_detection": true, "pm_proxies": []}, "protocol": "stomp", "se_linux": {}, "spm": {"priority": 5, "status": "none"}, "ssh": {"fingerprint": "SHA256:J75BVLFnmGBGFosXzaxCRnuIYcOc75HUBQZ4pOKpDg8", "port": 22}, "statistics": [], "status": "non_responsive", "storage_connection_extensions": [], "summary": {"total": 0}, "tags": [], "transparent_huge_pages": {"enabled": false}, "type": "rhel", "unmanaged_networks": [], "update_available": false}]}, "attempts": 120, "changed": false}

Am I doing something wrong or is there a bug ? I suppose that your host was condifured with DHCP, if so it's this one: https://bugzilla.redhat.com/1549642 The fix will come with 4.2.2.
