It seems that the issue is within the 'dd' command as it stays waiting for
input:
[root@ovirt1 mnt]# /usr/bin/dd iflag=fullblock of=file oflag=direct,seek_bytes
seek=1048576 bs=256512 count=1 conv=notrunc,nocreat,fsync ^C0+0 records in
0+0 records out
0 bytes (0 B) copied, 19.3282 s, 0.0 kB/s
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
0+1 records out
131072 bytes (131 kB) copied, 0.00705081 s, 18.6 MB/s

Гринуич-4Тема: 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:

Can someone give a hint ? Maybe it's related to gluster v6 ?
Can someone test with older version of Gluster ?
