It seems that the issue is within the 'dd' command as it stays waiting for

Changing the dd command works and shows that the gluster is working:
[root@ovirt1 mnt]# cat /dev/urandom | /usr/bin/dd of=file
oflag=direct,seek_bytes seek=1048576 bs=256512 count=1

Тема: ovirt 4.3.3.7 cannot create a gluster storage domain
Hey guys,
I have recently updated (yesterday) my platform to latest available (v4.3.3.7)
and upgraded to gluster v6.1 .The setup is hyperconverged 3 node cluster with
ovirt1/gluster1 & ovirt2/gluster2 as replica nodes (glusterX is for gluster
communication) while ovirt3 is the arbiter.
Today I have tried to add new domain storages but they fail with the following:
2019-05-16 10:15:21,296+0300 INFO (jsonrpc/2) [vdsm.api] FINISH

It seems that the 'dd' is having trouble checking the new gluster volume.
The output is from the RC1 , but as you see Darell's situation is maybe the
same.On May 16, 2019 21:41, Nir Soffer <[email protected]> wrote:
