HA - baby
I recently set up 2 RH8 servers to do High Availability failover for samba and nfs and this looks like the apropriate place to brag about it for a second.
This was f@$#ing awesome to work on specs: dagon: 2.4 GHz P4 1GB RAM 1 60GB IDE - system 4 120 GB IDE RAID 5 (3 disks + 1 hot spare=228GB useable space) kerebos: 2.0 GHz P4 512MB RAM 1 60GB IDE - system 4 120 GB IDE RAID 5 (3 disks + 1 hot spare=228GB useable space) The servers listen on a crossover cable and if it detects a communication problem, the other one will take over. Virtually seamless across the network with a total downtime of about 10 sec.

(- *minus the cost of the hardware) |
Any clue how to failover IP's for 5 different computers so they all have a failover point ?
