We've run web servers in primary/backup mode for years, but are now
looking to cluster two servers and potentially add a third. I'm looking
at two potential options for redundant data storage:
1) DRDB to mirror data drive from ServerA to ServerB, then use NFS
failover to mount whichever one is acting as primary. Could GFS work here?
2) NDB + RAID to mirror drive from serverA to serverB, then use NFS
failover to mount whichever one is acting as primary. Again, could GFS
work here?
I'm looking for recommendations from anyone who has specifically used
either of these two in terms of ease of management, speed, and
above-all, stability of the platform. Also, we're planning on using ext3
for the underlying filesystem. Any recommendations otherwise?
if I missed anything that might work well in this senario, I'd love a
heads-up. Unfortunately, shared SCSI, etc., is not an option. We're
using local drives with separate data partitions.
Thanks in advance for the help.
