I have a very similar situation and I'm interested to find out how people are doing to use DAS in these types of environments.

Hi,

Have a VRTX Chassis enclosure populated with two Dell PowerEdge M620 Blades and has a built-in DAS storage. Created a 1 TB Virtual Disk from the DAS storage using the Dell iDRAC interface. This block device is accessible from the two blades (CentOS 7 OS) like shown below,

=C2=A0[root(a)node1 ~]# lsblk /dev/sdc

=C2=A0NAME MAJ:MIN RM=C2=A0 SIZE RO TYPE MOUNTPOINT

=C2=A0oVirt rpms has been installed on both the blades with the aim of configuring them as oVirt nodes with Live Migration feature. But other than the DAS we don't have any storage which can be used as shared storage. So can some one please tell me whether the above block disk can be used as a shared storage (i.e mounted on the two nodes at the same time) and if it is possible how can this be done. Thank you.
