6:49 p.m.
A quick update, the storage directory is created with root.root so vdsmd is
not able to write, I managed to change the ownership to 36:36 and every
thing worked fine "after the directory has been created".
I think this is what happens behind the scene:
- check if directory exits or not.
- if not creates it with 755 , root.root
- sudo and mount file systems
- try to write __DIRECT_IO_TEST__ fails
- sudo umount
- directory gets deleted
Can someone confirm ?
Regards,
Sherif

HI,
I have centos 7.1 latest update for hosts and VM that hosts the hosted
engine, the hosted engine uses iSCSI storage and so far it is working
correctly *as expected* , I have 1 shared DC, 1 Cluster and trying to add
GFS2 storage as a master data domain, I am using corosync , pacemaker , pcs
to manage the DLM and cLVM that is also working as expected, however
whenever I try to add the GFS2 storage I get the following error message
from VDSM.log
