I have this setup (please check attached picture).
WAN link has dedicated 2048 Kbps (with average 14
miliseconds between nodes )
LB 1, 2, 3 Servers are Load Balancers
Node 1, 2, 3, 4 are Redhat Enterprise linux ES v4 +
MSA1000 storage has 30 Gig of Data right now, and can
grow beyond 100Gigs.
Can someone help me out to figure the best GFS
configuration to have:
1- Mirrored storage over the Wan Link ?
2- What options can be setup for asynchroneous
replication of the storrage if the WAN link is
becomes too thin for synchronous replication ?
3- Nodes 3 & 4 fail over Nodes 1 & 2, supposing that
Node 1 and 2 are unavailable ?
4- Does GFS over DRBD work at this time ? and have
someone implement it ?
Thanks for your help,
