[ovirt-users] Host in kdumping state

Hello I've got a faulty host that keeps rebooting itself from time to time (due to HW issues), that is/was part of the 3 hosts group hosting the HostedEngine, and now it always appears as "Kdumping" in the web administration panel. All my hosts are oVirt 4.1 on Centos 7.3 with glusterfs 3.7 but this one that was updated by mistake to Centos 7.4 with glusterfs 3.8. Is this due to the different OS/gluster version? How can I "reset" it? I want to remove it permanently and assign the HostedEngine to another host? Moreover, the main glusterfs volume, the one which holds the HE image, has some bricks on this failing machine (vm03): #  gluster volume status data_ssd Status of volume: data_ssd Gluster process                             TCP Port RDMA Port  Online  Pid ------------------------------------------------------------------------------ Brick vm01.storage.billy:/gluster/ssd/data/ brick                                       49156 0          Y       6039 Brick vm02.storage.billy:/gluster/ssd/data/ brick                                       49153 0          Y       99097 Brick vm03.storage.billy:/gluster/ssd/data/ arbiter_brick                               49159 0          Y       5325 Brick vm03.storage.billy:/gluster/ssd/data/ brick                                       N/A N/A        N       N/A Brick vm04.storage.billy:/gluster/ssd/data/ brick                                       49152 0          Y       14811 Brick vm02.storage.billy:/gluster/ssd/data/ arbiter_brick                               49154 0          Y       99104 Self-heal Daemon on localhost               N/A N/A        Y       6753 Self-heal Daemon on vm01.storage.billy      N/A N/A        Y       79317 Self-heal Daemon on vm02.storage.billy      N/A N/A        Y       41778 Self-heal Daemon on vm04.storage.billy      N/A N/A        Y       125116 What's the best way to replace them?
