Re: [Linux-cluster] Please correct me if I'm wrong, but...



We have ISCSI based storage and are using GFS during a demo period, but I don't think we can afford it after the demo period is over.

The fencing is another issue for us.  I need to learn more about that.  I'm not sure I'm fully grasping all I need to there.  I'm still trying to get nfs file systems mounted on a remote host. :)

Thanks,
Randy

Right.  That's the way I understood it to be.  Using ext3 would require 
us to have to umount and remount the file systems to the each host after 
the failure, though, correct?  In other words, would require 
administrator interaction.  GFS would do this automatically without 
impacting the users.
      
One would hope that the failover process handles mounting and
unmounting.  You do, however, need shared storage and suitable fencing
mechanisms in place.
    

... that is, with ext3.

With GFS, you just mount it on both nodes and the recovery occurs in the
background.  Again, shared storage + fencing are required.
