--- Comment #10 from Strahil Nikolov <hunter86_bg at yahoo.com> ---
All nodes are up and running. Everything is healed - issue is valid for gluster
v7.3.

VMs using "data_fast" , "data_fast2" , "data_fast3" & "data_fast4" (striped LV
in linux) fails to power up.

Brick log contains:

As you can see the issue is with a shard and not with the shard directory.

Previously (v6.5,v7.2) , when using dd with vdsm user - access is denied when
the first shard is accessed (aprox 65MB). When user root reads the file and
immediately vdsm user reads it - everything is fine (temporarily).
