[Users] which file system for shared disk?

2013-07-10 Thread Piotr Szubiakowski
Hi, we are developing an application where would be great if multiple host could have access to the same disk. I think that we can use features like shared disk or direct LUN to attach the same storage to multiple VM's. However to provide concurrent access to the resource, there should be a

Hi Piotr! I've used OCFS2 out of oVirt, so I can't tell you specifically about VM environment, but I suggest you use OCFS2 in place of GFS2. It is simpler to implement, so less components to configure and it care about fencing for you. On 07/10/2013 08:15 AM, Piotr Szubiakowski wrote: Hi,
