: 1.0.7 hi, We have a cluster of 20 hosts running ovirt 4.1.7 . And it became unstable. the data is stored on an HP Apllo 4530, with freeNAS and a cahce drive (optene) , a 10G network between hosts the problems we see: HE is jumping between hosts and crashes all the time, and even more when global maintenance is disabled. Another issue is that vms get cpu stuck messages. And hang for 10-20 seconds. looking at freenas/apollo dashboards shows that it is fairly idle. when global maintenance is disabled engine log shows it is restarted by ovirt very often any suggestions as for where / what to look for ? -- ------------------------ בעז ירום 05-2327-2320 boazya[at]gmail.com
