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

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 conv=notrunc,nocreat,fsync  0+1 records in

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:

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.
