thank you it's work now. All my host 8.2/8.3 are up and running. During reactivation of 8.2 host i saw the log line "updating cluster CPU..."

I tried to move guest from 8.2 host to 8.3 one but it failed.

Engine.log :

vdsm.log (target host) :

Another think i've noticed on event log of 8.3 host :

VDSM bombur-adm.cines.fr command SpmStatusVDS failed: Cannot inquire Lease(name='SDM', path='/dev/7586152d-338c-415d-93f4-74efd09c02fa/leases', offset=1048576): (2, 'Sanlock get hosts failure', 'No such file or directory')

But file seems to exist on host :

ls -l /dev/7586152d-338c-415d-93f4-74efd09c02fa/leases
lrwxrwxrwx. 1 root root 7 Dec 15 14:14 /dev/7586152d-338c-415d-93f4-74efd09c02fa/leases -> ../dm-7

I tried to reboot host & restart engine, set my 8.3 host as SPM ... same error.

Hi Lionel,

if you managed to remove the host (or move it to a different cluster) so that all hosts in your cluster are UP - you could try to put one of your running hosts to the maintenance and then back to active - the cluster settings should be updated on the host activation. You can look for the log "Updating cluster CPU flags and verb according to the configuration of the [cluster name]".

If that does not help, you can try to restart the engine.

Please let me know if that helps.
