Sorry, Lon gave me updated info about the MSA500. It isn't a parallel shared scsi bus configuration, so might work with gfs. However, we have never run with it before and not sure about the performance characteristics. Kevin On Wed, 2008-01-09 at 12:56 -0800, Coman ILIUT wrote: > We're using an

We're using an MSA500 actually, so what you're saying is that we're not using the proper hardware for GFS. Can you tell us how bad is this? The reason I'm asking is because we are already at the second version of our product using this solution and we did not have any issues before. So we never

Hi all, I am currently using version 1.0.4 of GFS and the scsi reservation binairies (scsi_reserve, fence_scsi, etc) are not there. Is it suppose to be like this or this is the distro I a using playing games with me (not my choice! It's Gentoo). If it's normal that they are not there, is there
