Hi, I have another spooky issue. CentOS 8.2, oVirt 4.4.1.10-1 I am trying to create vm on my HCI cluster (which in fact has only two nodes now, the third will be added later). I have created new 10GB disk on gluster storage (it behaves the same way when I chose prealocated or thin provision disk). Everything looks good (I was surprised how fast was this disk created) but when I run the vm then disk has only 4096 bytes. see http://mirror.slu.cz/tmp/ovirt_small_disk.png disk creation part of engine.log is here https://paste.slu.cz/?0e33e800609898d8#CEC2maoe7zk9b1zmnHaAENjaAnpiyzzGzPFSe... the same part in vdsm.log on SPM host https://paste.slu.cz/?e89fdce800c39b28#3UWw7dXxQAmZysMSKp5NbeTWMNDghZVh2NLEm... where could be problem? Did anybody experience this behavior? Cheers, Jiri
