Or would you have to run a shared failover service such as NFS on top of the two node cluster if you need multiple hosts accessing it?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Mainly ask because I assume recovery time from failover would be much quicker with a cluster filesystem (doesn’t have to fsck/remount), and reads (would?) be split over the two hosts instead of just one, so it should be slightly faster with two hosts serving read I/O requests instead of one.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
